Used in conjunction with the circuit protection devices – (RCD, RCBO, MCB and Surge Protection) – these four types of consumer unit offer the homeowner and electrician huge flexibility of circuit design and budget. It is important to understand that in most domestic properties it would be possible to use any one of the four types of consumer unit along with surge protection, the decision being governed by budget and attitude to circuit separation.
Goodwin Electrical strongly recommend a Consumer Unit with RCBO’s and Surge Protection.
Surge Protection explained
Surge protection is a device designed to protect a whole houses electrical devices from voltage spikes. Therefore extend life of devices, reduce replacement needs and repair costs. This is a must if you have sm
