Guide to the Consumer Unit

Below you'll find the different components of a consumer unit; hopefully you'll understand a lot more about the consumer unit by the end of our blog post.

Mains Switches

This particular component of the consumer unit controls the supply of electric in your property. In the event of an emergency, this should be switched off. This also controls all the other components in the consumer unit. 

Bus Bar

As for this particular component, it is only seen by electrician working on the consumer unit. It essentially locks in all other components into place and is a long strip of copper with teeth. 

RCDs (Residual Current Devices) 

This is what turn off the power throughout your home immediately after an electrical fault is located in your property. Essentially preventing you getting a fatal electrical shock by touching a live wire. RCDs monitor the flow of electric in your property; also as of 2008, all homes must RCDs fitted for safety purposes. 

Circuit Breakers

Finally, the last component to mention regarding the consumer unit is the circuit breakers. Each property has roughly six circuits with each being controlled by a circuit breaker. Like RCDs, circuit breakers trip and turn off upon discovering an electrical fault to protect you from receiving an electric shock. If a circuit breaker does trip, you can switch it back on. However, it is advised that you seek the assistance of an electrician to have them find out where the fault is.
