A Consumer Unit is the beating heart of your house – or at least it is where your electrics come from. It is a vital piece of the building infrastructure, but what is it and how do you choose one? This article will provide a guide to different types of consumer units, including RCD incomer, 6 way, RCBO, and Mains switch. Once you know what each unit is, you can choose the one that works best for your home.
Mains switch consumer unit
If you are looking to install a mains switch in your domestic property, you may be wondering what kind to choose. There are several different types of consumer units, each of which serves a different purpose. High Integrity Consumer Units are popular with electricians and domestic buyers alike, as they offer superior protection without breaking the bank. These types of units are especially useful for projects that involve twelve or more circuits. You can also purchase RCD Incomer consumer units, which are specifically designed for small circuits and don’t feature a main switch. They are controlled by a single specialist RCD.
A ‘Main Switch Consumer Unit’ is a basic version of a fuse board. These are usually supplied without any additional protection devices, other than a main switch. They may also contain an RCD or MCB, depending on your preferences. Dual RCD Testing are also very popular and feature two RCDs. You can choose a model that contains both types of protection devices to protect your property.
RCD incomer consumer unit
When it comes to choosing a RCD incomer consumer unit, there are a few key factors to consider. Modern consumer units are commonly made of metal or plastic. Their front openings are standardized, but they don’t use a standardized busbar arrangement. And, of course, they have to be CSA-certified. While it may seem counterintuitive, a dual-RCD consumer unit offers the best protection for two banks of circuits.
High-integrity consumer units have become a popular choice among homeowners and electricians alike. They offer excellent protection without breaking the bank. This makes them particularly attractive for projects with twelve or more circuits. RCD Incomer consumer units are another type of protection device. They are specifically designed for use in small circuits, and have no main switch. A single RCD manages all incoming electricity. They can be paired with an RCBO or two.
6 way consumer unit
Generally, a six way consumer unit is more expensive than a four way one. This type of unit costs about PS70 to PS85, whereas a twenty-eight-way unit costs about PS180 to PS200. A three-phase neutral board (TPN) controls the alternating current, allowing for more constant power delivery than an SPN board. TPN units are slightly more expensive, costing between PS130 and PS1,000 for a four to eight way board and PS200 to PS1,600 for a twelve to 18-way unit.
The fully loaded consumer unit is the most common and economical type. It comes with a complete set of MCBs and two RCDs and creates ten to fifteen usable ways. However, it does not provide accurate circuit separation. A split load consumer unit includes a main switch and a residual current device (RCD).
RCBO consumer unit
Choosing an RCBO consumer unit is an important part of home safety. They can help prevent fires by preventing surges from damaging electrical wiring. There are a few different types of consumer units, but all have the same main features: a double-circuit-breaker (RCB) and surge protection. The most common types of consumer units are listed below. If you are not sure which type of RCBO you need, you can read the RCBO consumer unit guide for domestic buyers.
RCBOs combine the functions of an MCB and RCD into a single unit. Previously, these two components were purchased separately, and then configured to meet your needs. Now, you can install one or combine them for a more advanced safety system. Whichever type of RCBO you choose, you can feel safe knowing that it will work properly. There are many options available to you, including programmable and manual controls, and you can also find a consumer unit that is suitable for your needs.
