5 Key Places To Install Metal Enclosures

Metal enclosures are an essential piece of equipment that helps to protect you from electrical hazards in your property. Simple yet effective, a metal enclosure surrounds a circuit, switch or display to provide a barrier between yourself and electrical equipment and thus to prevent electric shocks.

Steel enclosures (as well as enclosures made from other materials such as plastic, aluminium and carbon steel) are very common fixtures throughout the home. Some enclosures have viewing panels so that property owners and electrical professionals can read electrical displays or just check at a glance that everything is working smoothly.

Here are 5 key places to install electrical enclosures.

1. Around telecommunications equipment

Broadband cables and computer servers are just two examples of telecommunications equipment that needs to be protected by electrical enclosures. This equipment is typically very sensitive and so needs a sturdy casing that can keep it safe, whilst also providing adequate ventilation so that it does not overheat. This latter requirement is very important for high powered equipment such as computer servers, as these can slow down and cause disrupted or even totally interrupted data processing if they overheat.

Floor standing enclosures for telecommunications equipment can be located either outdoors or inside a property, and they can be either publicly maintained or private property. The enclosure around telecommunications equipment can also be mounted on a pole or on a wall. Many telecommunications companies make a particular type of high quality enclosure a key part of any installation that they perform. 

2. Fuse boxes

Fuse boxes are a great example of steel enclosures that are used by ordinary homeowners all the time. The outer metal casing of a fuse box protects the switches on your fuse board and also provides you with an additional layer of protection from the live wires that lie just beneath the fuse board. Fuse boxes are usually situated either within a lockable cupboard or high up on the wall to keep them out of the reach of children.

Many fuse box enclosures have viewing windows. That means that if a switch trips within your home, all that you need to do is to take a look through the viewing window of the enclosure around your fuse box and you will instantly be able to pinpoint where the problem lies. 

3. Floor standing enclosures for utilities

Vial pieces of equipment such as the control panels for utilities such as wind farms or industrial freezer systems very often benefit from being enclosed in a specialised metal framework. The metal enclosures used for utilities can have a number of benefits, including reducing condensation around a control panel, ventilation (or other forms of heat management), filtering signals and shielding the control panel from electromagnetic currents that might interfere with their working.

Floor standing enclosures are the most popular choice for utilities, and these cabinets can come in very large sizes to accommodate the larger control panels associated with utilities such as wind farms. Swing doors, shelves and additional ventilation units are all common additions to the enclosure in this context.

4. Warehouses

Condensation and electromagnetic signals are not the only contaminants that electrical equipment needs to be protected from. Electrics also need to be protected from dust, and this is found in abundance in warehouses. Any warehouse or other dusty building or space that uses electrical equipment should thus also have an electrical enclosure installed to protect that equipment. The main way in which dust adversely affects electrical equipment is by impeding electrical conduction.

A layer of dust can also have an insulating effect on a circuit and cause it to overheat. Finally, dust often attracts and absorbs moisture, which can lead to short circuiting. Protect your warehouse’s electrics from all of these ill effects with one simple step: installing a metal enclosure around them. 

5. Single sockets in high risk areas

When we have young children or animals around the house, even a single everyday socket can become a safety hazard. Child proof electrical enclosures are a simple yet very effective way of keeping your children safe from electrical hazards. Though they are the smallest type of enclosure discussed here, these casings for single sockets are widely available and widely used.

They can be installed very quickly with just a couple of screws and they can be fitted with child proof locks so that adults can open and use them when necessary. These casings for sockets are also very useful if you have a socket in need of repair (for instance, if a socket has begun to come away from the wall or if it has live wires showing) and want to protect tenants or householders from it until you can get an electrician in to repair it. Purchasing a few sockets sized casings is thus a very good idea as you never know when you might need them.

The importance of steel enclosures

A metal enclosure can be used to protect your electrical kit from all kinds of contaminants, including dust, water and EMC. It can be used to stop equipment from overheating and it can also be used to protect human beings from electrical hazards. Your enclosure can be placed in a warehouse, outside on the street or over a single socket in the home.

The best place to situate your enclosure will depend on the type of equipment that it is designed to go with – an enclosure can be wall mounted, pole mounted or free standing depending on the context. Viewing windows, swing doors, shelves and child safe locks can all be used to customise your enclosure. Versatile and practical, these casings are indispensable to anyone who cares about practising good health and safety.

Voltage Optimization Explained

Voltage optimization is the process of systematic reduction in the level of voltages received by a consumer (this kind of consumer).

By reducing the supply voltage to your electrical equipment you can reduce your power consumption and energy usage. This process is controlled via voltage adjustment devices which are designed to reduce energy costs and save money.

Voltage Optimisation Explained

Voltage optimizers act like a type of transformer, taking in the higher input voltage from the electricity grid and converting it into a lower, optimized output voltage.

As they are installed at the incoming mains electricity supply, voltage optimization devices deliver an energy efficient power supply to all of the connected electrical equipment. They allow all of the electrical equipment to enjoy the benefits from the optimized supply.

Advantages of Voltage Optimization

One of the biggest advantages of voltage optimization is that it helps to reduce your power consumption, which in turn helps to reduce your energy costs and ultimately saves money.

Click the image below to see an example case study.

As an example, a home is designed to run at a nominal voltage of 230V. The voltage going into the building is supplied by the mains grid, which can be as high as 253V. However, a voltage of just 220V is required to power the electrical equipment in a business or home.

As AC (alternating current) voltages fluctuate – these devices reduce and maintain a voltage of 220V.

Supplying electricity at higher voltages will increase the necessary consumption, however if optimization is carried out, the voltage could potentially be lowered by about 10%-15%.

With your voltage better optimized, the home or business will now be consuming 220V, which reduces the overall consumption of electricity.

Another huge advantage to installing voltage optimization is that it helps to prevent damage to your electrical equipment that’s caused by power surges or blowouts.

This means that your electrical equipment will last much longer and ensures you get the optimum lifespan.

Ensuring your electrical equipment lasts longer helps to reduce the rate at which you have to purchase replacement equipment, helping you save your money on potential replacement and maintenance costs.

The Best Types of Equipment to Benefit from Voltage Optimizers

A voltage optimizer is an important piece of equipment to help reduce your energy consumption. But where are the best places to install one? It is important you only install them in the places where you’ll see the most improvements. Here are few options for you to consider:

Voltage optimisation can benefit motor control gear

Motors – This is a big area where you can make great savings by ensuring your voltage is optimized. It is shown that optimization of motor systems can help to reduce your power consumption significantly and help you save more money in the long run.

Voltage optimisation devices can help to save energy on lighting
– If you don’t want to consider switching your old magnetic ballast or incandescent lighting to LED lighting, you may want to consider a voltage optimizer. When you optimize your voltage, magnetic ballasts or incandescent light tubes will consume less energy. Switching to LED can save up 85% and a voltage optimizer can increase the savings even further.

Common Power Problem Solved by Optimizing Your Voltage

  • Overvoltage– This refers to the input of a higher voltage than a piece of electrical equipment requires and is even designed to operate at. A national UK power grid outputs an average of 242V but this can be as high as 252V in some areas. While most pieces of electrical equipment are designed to only use about 220V. This immense and unnecessary voltage can lead to a reduction in the lifetime of electrical equipment, an increase in power consumption and no improvement in performance.
  • Harmonics – These are the waveforms of currents and voltages at multiples of any fundamental frequency of the national grid supply. They come about as a result of non-linear loads, including variable speed drives and discharge lighting. When the level of harmonics becomes too high, they can lead to damage to some pieces of sensitive electrical equipment. Similarly, it leads to a reduction in the efficiency of the HV (high voltage) transformer. Voltage Optimizer units come with a voltage stabilizer which helps in reducing these high levels and prevent any potential damage caused.
  • Transients – These are brief and very large destructive surges in the amount of voltages. They can come as a result of lightning, switching of a large electrical load or switching between power sources. Although they last for a fraction of a second, they can be very destructive to any electrical equipment. They can easily cause data loss, shorten the lifetime of equipment and degradation of electronic components. A Voltage optimizer comes with transient protectors which aid in power factor correction.
  • Phase Voltage Ambience – Commercial sites and industries are provided with 3-phase electricity. If there is any sort of imbalance between the phases, overheating might occur and this leads to wastage of energy. A voltage regulator can easily help balance the voltage among these phases thus saving bringing about energy efficiency and improving longevity of the motors.
  • Power Dips– This is the reduction in voltage over a short duration, but in minimal cases it might take a longer period. Power dips can cause machinery to stop as well as dropping out of contractors and relays.

The energy saving that is portrayed by voltage optimization is an aggregation of improved efficiency of equipment across the site.

Therefore, you must ensure that you employ a voltage optimized system that will not end up consuming more energy or power that it is deemed to save. It is therefore important to check out some factors to consider when installing an optimizing device.

Key Features to Consider When Purchasing A Voltage Optimizer

  • Efficiency – the VO unit to be installed must have an impeccable efficiency of about 97% to 98%. This should be constant during different load conditions and should even work with the lowest input voltage. Whether the voltage optimizer has a low input of 50% or the highest input of 100% it must be able to operate with full performance. In addition, it should not contain any wearable or consumable parts, this is to ensure no maintenance or repair is undertaken thereafter. The lifetime of an effective optimizer is around 25 years.
  • Fast Voltage Management – the VO system should manage the voltage in an independent and fast manner. The transformers consisted on each phase, switching elements as well as power control gadgets should all be independent on each phase, so as to maintain full performance of the system. The system should have high speed stabilization in order to ensure that machines don’t fail, which could affect production rate.
  • Uninterruptable Functions – A VO system should be able to keep manufacturing operating even when there is a breakdown or overload. For this reason, an automatic system that can bypass these issues is preferred. Some come with a voltage stabiliser to counter power surges. After the load or problem is solved, the system comes back on and continues functioning normally.

The national grid voltage is set higher than the nominal value so that users can attain sufficient voltages at the end of the distribution. This also reduces transmission losses. The distance of a plant from the mains actually determines the voltage it will receive. Since plants are offered electricity on a 3-phase, the unbalanced voltage can be quite detrimental and destructive to equipment which in turn leads to performance losses.

Voltage optimisation in these facilities helps in power factor correction, balance voltage across the system bringing about energy efficiency across the grid as well as longevity of machinery. However, only long lasting, maintenance free, high speed and automatic VO systems will lead to an effective and significant saving in power consumption. They will also see to it that machinery and electrical equipment last long thus reducing maintenance and repair costs.

Without a voltage optimization device you’re potentially paying for an additional 32V that your devices don’t need. With the continuing worldwide increase in demand for energy, voltage optimization is a step in the right direction.

One day, voltage optimization may be a necessity for every home and business.

Ways to Cut Down Energy In 2016

If you are still getting crazy electricity bills, its time you rediscovered some of the ways you can cut down on these costs. Research indicates that half of a household’s overall energy usage goes towards heating and cooling costs. This not only affects the pockets, but it also degrades the environment. Some of the effective ways to save money on electricity bills include:

If you haven’t already switched to LED lighting, its time you reconsidered. Ceiling spotlights look great but end up consuming too much energy. Over time, they also get very hot when left on for a certain period of time.
Invest in LED bulbs as they emit less heat and they provide better lighting compared to fluorescent and incandescent bulbs. It is also estimated that LED bulbs can reduce your electricity costs by 90%. Only buy high quality LED bulbs from renowned manufacturers and check for the CE safety branding. A qualified electrician can help you choose the right bulb if you’re in doubt.

Remember to keep the lighting fixtures clean as dirt absorbs light. Hold the bulb with a piece of clothing as bare hands can easily damage the bulb.

If you are using an air conditioner, remember to set the temperature at 25 degrees Centigrade. You can invest in a programmable thermostat as this allows you to control the temperature even when you are not home. Regularly clean filters as clogged filters make the fan work harder and this means more energy consumption. Additionally, keep your AC in a clean area and in a place where air can flow freely.

Keep your fridge or freezer between 0-s degrees centigrade. Frozen food cools the fridge. Remember to avoid over filling as this may restrict the circulation of air in and around the compartments.
When using your kettle, boil enough water and do not overfill.

Adequately insulating your attic can reduce your electricity bills by up to 20%. Always check to see if the attic is well ventilated to allow the circulation of air.

Ways To Prevent Electrical Faults

There are different categories of electrical faults that can occur in both the home and at work, usually occurring either through the ‘hard wiring’ of the electrical distribution system or at the individual appliance level. Electrical faults are dangerous, with the main risks being electric shock, fire and damage to equipment and property. Preventative steps can, however, be undertaken quite easily.

It’s critical to get the hard wiring checked by a competent, qualified and certified electrician. Distribution/fuse boards can become out of date and essential features such as trip switches can be at risk of malfunctioning. Old and poor wiring running through a property increases the risk of fire and the malfunction of individual appliances. A competent electrician will be able to make recommendations as to what updates are needed to ensure that the property’s safe and legal.

Individual electrical appliances need to be regularly visually inspected to ensure no faults are developing in the cabling or plug and this is an easy task for everyone to do periodically. An electrician can also carry out a portable appliance test to make sure the individual item is safe and this is a legal health and safety requirement for portable appliances that are used in the workplace.

Appliances must always be used and stored in the environment that’s appropriate to their intended use. Flexes and cables must be protected from adverse wear and tear, such as the family pet chewing the cable or the office chair running over and crushing a trailing lead. Electrical faults often occur through misuse of equipment, such as dry equipment used in a wet environment or appliances being used outdoors in harsh conditions or leads being over-stretched and/or twisted.

The best way to prevent electrical problems is to use equipment appropriately, inspect it regularly, and replace it when it’s reached the stage where it fails to function properly and becomes unsafe. Also, have the structural wiring checked every few years because any issues that develop will often do so without the owner/occupant being aware.

Guide To Electric Cars In 2015

There has been a huge increase in electric cars on the roads of the UK in the last few years.

The figures are up from around 3500 in 2013 to the impressive figure of nearly 40,000 vehicles in 2015.

This increase has come about for several reasons. There has been a sea change in the attitude of the public towards electric vehicles, an improved network of public re-charging points, and a greater choice of vehicles coming on the market.

Although many people would like to join the increasing number of those driving electric vehicles, some aspects of owning one should be taken into account.

For example, it is advisable that the daily mileage should not exceed 100 miles.

The ideal journey would be one the owner is very familiar with and is aware of any possible traffic hazards and detours.

The owner should have access to off street parking with a facility for recharging the car’s battery overnight.

However, if off-street parking is not available, there is government funding that allows householders to apply to their local councils to have a public on-street charging point installed close to their home.

At the time of writing (November 2015), electric cars are dearer than those fuelled by diesel or petrol.

In 2011, the purchase price of some electronic vehicles has been subsidised by grants that reduce the price of eligible cars by 25% up to a limit of £5000 and 20% on vans with a limit of £8000.

The Office for Low Emission Vehicles receives all the required paperwork from the dealer selling the vehicles and the grant is deducted from the price at the point of sale.

Even with grants, the price of new electric cars and vans tend to be higher than internal combustion driven vehicles. Never the less, with the cost of electricity being far cheaper than petrol and diesel it is possible to save around £700 or more on an annual mileage of 10,000 miles. Electric vehicles are exempt from car tax and this alone saves £145 a year.

What is Motor Control Gear?

What is Motor Control Gear?

A motor control gear is a specifically designed electrical motor type that produces high torque or force while at the same time maintaining motor output at a low speed or low horsepower. These control motors are found in lots of diverse applications, some of which are perhaps being used in your house.

Typically, gear motors are used in devices like garage door openers, control knobs on your washing machine, electric alarm clocks and even in that simple can opener. The common usage in commercial applications includes cranes, commercial jacks, and hospital beds, among very many others.

How does it Work?

Primarily, a control gear motor is used to reduce speed in a gear series, which in turn creates additional torque. This gets achieved through a gear box or an integrated gear series getting connected to the main shaft and motor rotor via a 2nd reduction shaft. Then the 2nd shaft is linked to the gear box (or gear box series) to create what’s referred to as a reduction gear series. In principle, the longer the reduction gears train or series, the lower will be the output of the final.

A very good illustration of the motor control gear principle is the electric time clock using seconds, minutes and the hour hands. A synchronized AC motor employed in powering the clock usually spins the rotor at about 1500 revolutions each minute. Because, the hands would be moving very fast and at same speeds, a reduction gear series is employed in slowing down the clock hands movements.

In commercial applications, they are commonly used in situations where an equipment piece needs to have the capacity of exerting high quantities of force so as to shift or move an extremely heavy object. Good examples of such application would be the lift jack.

Bottom Line

If you have watched a crane in operation, then you have seen the best example of the way a motor control gear works. The motor employed in most cranes is the typical gear motor type that utilizes the basic speed reduction principles to increase force or torque.

5 Big Benefits Of Steel Enclosures

Steel is an alloy of iron and other elements such as carbon. It is primarily used for construction and other applications due to its low costs and high tensile strengths. Steel fencing is preferred over other forms of fencing due to its numerous advantages. Here are the five principal benefits of using steel enclosures.

Durable and Safe

Steel enclosures are resistant to fire, pests and corrosion. The enclosures can withstand extreme environmental conditions, like extreme hot and wet climates. Steel fences are resistant to scaling and can retain their strength at high temperatures. Steel portrays exceptional stoutness at cryogenic temperatures. Steel does not require treatment with pesticides or preservatives. This makes a steel fence to be safe for persons handling and living around it.

Environmental Friendly

Steel framing lasts longer compared to wood or plastic framing. It is both easy and light to move around and produces less raw material waste. Steel fences are easy to clean. This makes them the first choice in kitchens, hospitals and pharmaceutical processing facilities. At the culmination of its long life, steel can be fully recycled and used to make new steel enclosures.

Cost Effective

It is more economical to use a steel enclousre in the long run, rath than using another type of enclosure. Its initial purchase cost might be slightly higher at first compared to prices of others. Nevertheless, steel enclosures lasts for long with less maintenance required. Construction of a steel fence is quick and simple.

Fire Resistant

Steel frame housing are fire resistant. They have been tested and proven to endure austere bush fires with temperatures above 1000°C. Since steel is non-combustible, it reduces the volume of flammable materials in a home.

Premium Quality

Here at Expert Electrical, we pride ourselves on being able to offer premium quality steel enclosures for an affordable price. With our branded enclosures, you can ensure you feel peace of mind for your clients.
