Product Information

Each MCB is installed by clipping it onto a DIN bar and the "teeth" of the bus bar are inserted into the base of each MCB. This carries the live current into the MCB and the cable that supplies the given circuit are connected to the top section. The first type is the single load consumer unit. This is where the incoming mains power is first taken through a double pole isolation switch, which then in turn feeds a live bus bar that supplies each MCB on the board. Disconnect the power supply (and make sure it is really switched OFF) before servicing, repairing or installing electrical equipment. To do so, switch off the main switch in the main consumer unit or distribution board. The terms ‘consumer unit’ and ‘distribution board’ are often used interchangeably, but they are not always the same thing. A consumer unit is a type of distribution board, but not all distribution boards are consumer units.

How many ways and modules are needed? Plan how many banks of circuits you’ll need, which will tell you how many ‘ways’ you require. Then plan the number of individual circuits to give you the number of modules. But it’s always worth allowing for extra in case any changes or additions are needed to the circuit layout in the future. A consumer unit is the type of panelboards seen in most UK homes, recognisable as a metal or plastic box containing breaker switches. But a distribution board is typically used in commercial buildings. It works in a similar way to a consumer unit in a home but on a larger scale. Its job is to safely deliver the right electricity voltage to each area of the building. Often, local regulations dictate how these boards are configured, and for that reason, distribution boards are fully customisable.RCBO’s used in a consumer unit in place of RCD’s – Image courtesy of the BS7671 18th Edition Wiring Regulations High Integrity Consumer Unit / Three-way Split Consumer Unit

RCD’s also work by detecting an imbalance between the Live and the Neutral conductors and this feature is a requirement for all Class 2 double insulated equipment. When it comes to matching an MCB to what is now the equivalent imperial rating, these are as follows: When it comes down to it, the only person(s) able to do this are those that are Part P registered. If however you ignore this and do carry out electrical work that you’re not allowed to, this is illegal and also can invalidate your home insurance and cause potential issues when trying to sell your home. Once the incoming live is connected using a bus bar for each MCB, the next job is to connect each circuit to it’s relevant MCB.I frequently do this for customers who are putting in a log cabin or such, they do all the trench digging and cable laying and I do the fun part!! - Obviously, when a consumer unit is being installed the power to your entire house is isolated so that everything can be connected up and tested before it put live for use!
