Your Guide to Choosing the Best Consumer Unit

As you may already be aware, here at Expert Electrical, we have a panel of experts who are ready and willing to take your call and answer any and all questions you may have. This is one of our promises to our customers, and we are glad to say that we have been able to fulfill and keep this promise for years.

One of the aspects that we like to prioritise is answering our customers’ questions about certain products and their usefulness – such as consumer units as well as RCDs, circuit breakers, and RCBOs. If you have questions or concerns about the above-mentioned products, we’re here to give you the answers you need.

The basics on consumer units

 Consumer Unit

Almost every property which has an electric supply – which is most modern properties today – will have a consumer unit in order to distribute the proper amount of electricity to the different circuits in the property. A consumer unit has a number of important purposes, but one of its most essential purposes is to enable the use of a variety of circuits which can also be protected individually by a circuit breaker.

For instance, your property can have a separate electricity supply for the upstairs area and the downstairs area, and your property can even have a separate electricity supply for the outdoors or for its exteriors. This is where the importance of a consumer unit comes in, because it allows different circuits to be used for these electricity supplies.

The consumer unit is basically the centre point for your electricity supply – it supplies the essential wiring system for whatever electrical sources you may have in your property, building, or household, which normally includes lighting, plugs and sockets, and so on.

The modern use of consumer units

When they first came out, consumer units originally housed electrical fuses and were also known by the name ‘fuse boards.’ But today, things are a bit different in that miniature circuit breakers (also referred to as MCBs) have significantly replaced the original fuses. So if there is ever an electrical overload, the miniature circuit breaker (MCB) can be easily reset by you or anyone with a simple flick of the switch. A fuse, however, would have to be replaced (it should be taken out first, of course) by a professional, and the professional should also be in charge of rewiring it. In certain cases, this can cost a bit of expense. But MCBs and circuit breakers fulfill an important purpose, particularly when it comes to protecting your property or household from fires and other accidents.

Modern Consumer Units

Another purpose for a circuit breaker would be for the disconnection of the supply of electricity, which allows you or someone else to safely and easily change or replace a light bulb, replace a switch or plug socket, and more.

Ensuring safety for your property

If you would like your property’s safety to be further enhanced with the proper circuit protection, you can make use of a safety device which you can use for the disconnection of electricity. This is particularly useful if there is an actual imbalance or disparity in the current of electricity.

Property Safety

The safety device we are speaking about is called a residual current device, also known as an RCD. This special safety device can provide you and your property with an extra layer of protection because it has the ability to trip out in a much faster manner compared to the normal or standard circuit breaker. The RCD, or residual current device, not only provides this additional layer of protection – it can also save lives because it is able to disconnect in such a quick way that it prevents humans from suddenly being shocked by electricity. And, with the recent enforcement of regulations, particularly the 17th edition regulation, it is required nowadays for there to be a residual current device or RCD installed in a consumer unit. However, you should also know that rather than using an RCD, you can also make use of an RCBO (a device which is a combination of a miniature circuit breaker and an RCD).

Details on Chint’s consumer units

Chint is one manufacturer which has been specialising in miniature circuit breakers, circuit breakers, and other consumer units for years. The brand has always been preferred by electricians and other electrical experts, and for good reason.

One common and popular consumer unit produced and manufactured by the Chint brand is distinguished by its make-up, since it is made from Acrylonitrile Butadiene Styrene, or ABS. This polymer is known for its flame retardant properties, and it follows that it has a great insulation property when it comes to electricity as well. These properties make it an ideal polymer or material for extra protection.

But whilst ABS is a great choice of material for consumer units, consumer units are still also made from steel. A consumer unit made from steel is usually maximised in industrial locations and properties, or if armoured cable is in use. A steel consumer unit is usually shaped like a box, and it is accompanied by a lid that is of a polycarbonate transparent material. It also comes in a variety of sizes.

More on small units and large units

If you are interested in smaller consumer units, there is one kind that is popular with many customers. One example of a smaller unit for circuit protection is a garage unit, and this comes with a single circuit breaker and a residual current device or RCD. If you are interested in a larger consumer unit, on the other hand, you have the option of choosing double-stacked units (usually comprised of two residual current devices along with a main switch) – and this provides ample circuit protection for as much as 32 electrical circuits. Larger consumer units like these are most appropriate and used more often for industrial settings as well as commercial settings.

The conclusion

At the end of the day, the consumer unit is an altogether crucial component, being the primary electricity distributor in any household or property. It would be a risk and would pose a danger if you only have a single circuit which runs through your household or property without any circuit protection. It’s easy to realise the usefulness and impact of the proper consumer unit that contributes to circuit protection, because it has saved – and continues to save – a good number of lives each year.

More Commercial Lighting Products Available Today from Our Venture Lighting Range

Venture Lighting not only specialises in commercial and industrial lighting, however – it also offers a broad selection of display lighting products, emergency lighting products, flood lighting, street lighting, and domestic lighting products. Let’s take a look at the newest offerings from this lighting product manufacturer.

Venture Lighting

The top features of Venture Lighting products: what you can expect?

With Venture Lighting, quality and versatility, as well as energy efficiency, are of paramount importance. The company has been in existence for over 30 years, and this has enabled Venture Lighting to improve its offerings and expand its range for the benefit of customers who have detailed and specific lighting needs.

  • The CE mark

First of all, Venture Lighting products have the European Community ‘CE’ mark, which signifies that its items comply with the requirements of all important directives from the EU.

  • Warranty

Venture Lighting can honestly say that it has one of the best warranties for its lighting products around. Venture Lighting has made a promise that all its products are guaranteed to work and operate for the period it is stated to operate. So, if a product has a guarantee of 5 years, then customers can expect this product to function for a minimum of 5 years.

  • LED life and L80 rating

All the Venture Lighting luminaries have published LED life figures of L70, B50 unless specified otherwise. The classification refers to the light output of the product, so if a product is specified to have L70 classification and 50,000 hours, then it will produce, at the very least, 70 percent of its output for 50,000 hours. If a product has an L80 rating, it follows that its output will be higher than L70.

  • The IP rating

IP rated products – products which have a marking of Ingress Protection – provide a degree or level of protection against ingress. Ingress, in this case, is classified as dust, water, body parts like fingers and hands, and accidental contact. The level of protection will depend on the classification (e.g. IP65 which offers resistance to both water and dust).

Of course, there are other features you can expect from Venture Lighting products, such as ECA compliance, class 1, 2, or 3, and the Digital Addressable Lighting Interface, or DALI driver.

The Real Benefits and Advantages of Modular Floor-Standing Enclosures You should Know About

Without a doubt, when you are looking for enclosures for your electrical systems and installations, a modular floor-standing enclosure is better than most. Compared to traditional or standard uni-body floor standing enclosures, modular floor-standing enclosures offer a lot more benefits. But the fact is that there is often the mistaken impression that modular floor-standing enclosures are more expensive or are less flexible or versatile, but that’s just not true at all. Here is your guide to modular floor-standing enclosures – and what their real benefits and advantages are.


What is a modular floor-standing enclosure?

The most basic advantage of a modular floor-standing enclosure is its strength – strength that is not only literal, but figurative as well. The frame of a good quality modular floor-standing enclosure will be made from metal, with holes that can be punched in or pre-punched before delivery so users will no longer have to do any welding or drilling when adding accessories. With modular floor-standing enclosures, several frames can be attached to each other (whether it’s side to side, side to back, back to back, top to bottom, and more) so there is a seemingly infinite variety of configurations. What’s more, modular floor-standing enclosures are convenient and easy to use compared to traditional enclosures with one body with metal parts and seams that are already welded together, which do not allow for easier configurations or additions.

Modular Floor-Standing Enclosure

It’s functions

The primary function of a modular floor-standing enclosure, as you may already know, is to protect workers and staff from the risks of issues with electrical equipment. The second purpose of a modular floor-standing enclosure is to protect the equipment itself from its surrounding environment. Whilst a uni-body floor-standing enclosure offers the same protection as a modular floor-standing enclosure, the modular enclosure offers the added benefit of allowing an integrator, designer, or user to make more varied assemblies, ranging from the most basic to the more complex, according to their needs or requirements.


The main physical distinctions between uni-body and modular floor-standing enclosures

There are a number of differences, most notably physical, between uni-body and modular floor-standing enclosures. First is the hinges or latches. Almost all uni-body cabinets or enclosures make use of piano hinges for the doors. The latching is often accomplished with the use of several clamps which are placed around the perimeter of the door, or a handle. But modular floor-standing enclosures are different. A typical modular floor-standing enclosure will feature captive, discrete or distinct hinging which is not easily noticeable, allowing for better aesthetics.

There is also another difference when it comes to rails. With modular floor-standing enclosures, rails can be added in simply by sliding the panel from the front, the rear, or the side openings. But with uni-body enclosures, the rails can often only be inserted by laying the actual uni-body enclosure or cabinet onto its back and then lifting the unit’s panel with the use of a forklift or a crane.


The intangible distinctions between uni-body and modular floor-standing enclosures

There are also a number of intangible or non-physical distinctions between uni-body and modular floor-standing enclosures. For one, modular floor-standing enclosures allow for a cleaner, more efficient, and more productive plant or production area. The entire floor or area will not only be cleaner and more aesthetically-pleasing, it will not look ‘dated’ as well. With a modern modular floor-standing enclosure with hidden hinges for the doors and single locks (not ugly, noticeable clamps), the plant area becomes more organised and looks more spotless and contemporary.

Another intangible distinction between uni-body floor-standing enclosures and modular floor-standing enclosures is the fact that modular floor-standing units or enclosures offer more flexibility, especially when it comes to making future changes. If the unit needs to be changed or modified, it can be done with ease and convenience, in a much smoother and faster operation. If, by chance, there are any mistakes, these can be easily corrected with a modular floor-standing enclosure compared to a uni-body enclosure.


Some common misconceptions about modular floor-standing enclosures

As mentioned, there are some common misconceptions about modular floor-standing enclosures, particularly in regards to its strength, number of parts, assembly or configuration, and cost. These misconceptions have definitely been proven wrong by some high quality modular floor-standing enclosures today, such as the range of floor-standing enclosures from Tempa Pano.

Let’s take a look at some of these misconceptions – and disprove them:

  • Modular floor-standing enclosures lack strength and durability

Some think that since the walls of a modular floor-standing enclosure are thinner than that of a uni-body enclosure, they are less sturdy or strong. This is entirely incorrect. The fact is, the overall strength of a typical modular floor-standing enclosure does not come from its walls, but rather from its frame. This is because the load that is exerted on the modular floor-standing enclosure because of the equipment’s weight is transferred to the enclosure’s vertical framing.

  • Modular floor-standing enclosures require a lot of parts that need to be ordered separately

This is another misconception about modular floor-standing enclosures – that a typical enclosure will consist of so many additional parts that need to be ordered separately in order for the enclosure to be fully assembled. The fact is that a typical modular floor-standing enclosure will usually just consist of two main parts: the core assembly or frame (along with the mounting panel) plus the side walls. There are some other parts included as well, such as the door, the mounting plate, the top cover, the rear panel, and the side rails, etc., but these actually allow for easier installation since they are already pre-fitted – and they don’t have to be ordered separately.

Another related misconception about modular floor-standing enclosures is that assembling them requires some special skill or knowledge. This is not true at all – whilst a little bit of work on assembly is necessary, the accessories of the system can be added on by anyone without any special training. With a uni-body floor-standing enclosure, any modification would require more challenging work such as welding, cutting, or bending. With a modular floor-standing enclosure, this is not necessary.

  • Modular floor-standing enclosures are more costly than uni-body floor standing enclosures

The fact of the matter is that the price of both modular floor-standing enclosures and uni-body floor-standing enclosures do not differ greatly from each other. They are almost the same price, and, what’s more, if you use a uni-body floor-standing enclosure, there are usually some hidden expenses as well. Also, a uni-body enclosure often has a shorter lifespan than a modular floor-standing enclosure.
