Consumer Units explained
The modern consumer units replaced old style Fuse boards as the requirements for electrical safety changed with the latest editions of the wiring regulations.
The electrical system within your house is often hidden away, with little thought given to it until there is a problem! It's essential to have things inspected regulary to ensure things are working as expected.

So What is a consumer unit?
Modern consumer units are designed to be safe, flexible and upgradable. As you can see from the image below, there are a few main parts that make up a consumer unit. We explain what each part does below.
Often houses still have old style fuse boards installed. Whilst still serving a purpose after 30 years they don't offer the level of safety a modern consumer unit will provide.
At Chris Johnson Electrical we only us the highest quality units to ensure years of trouble free use and protection. A few images from some of our recent installations are shown below
Main incomer - This is the main switch for all circuits served by the consumer unit. It is double pole meaning it isolates both the incoming live and neutral.
RCD - An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide.
MCB - Miniature Circuit Breakers MCBs are installed in modern consumer units, and are a convenient alternative to fuses as they can be reset without having to replace wire with a simple flick of a switch or button.
This video gives you some more information on the importance of having an RCD and how to test it.
