What is the difference between an RCD and an MCB? +
An MCB (Miniature Circuit Breaker) protects against overcurrent and short circuits — it is the modern equivalent of a fuse. An RCD (Residual Current Device) protects against earth leakage, which is what can kill you if you touch a live wire. Modern consumer units use RCBOs, which combine both functions into a single device per circuit, giving you the best protection. If your consumer unit still has rewirable fuses, it is overdue for an upgrade.
Do I get a certificate after electrical work is completed? +
Yes — for any notifiable electrical work (new circuits, consumer unit replacements, bathroom/kitchen installations), your electrician must issue an Electrical Installation Certificate and notify your local building control. For smaller jobs like replacing a socket or light fitting, you should receive a Minor Electrical Installation Works Certificate. Keep these certificates safe as you will need them when selling your property.
My RCD keeps tripping — what should I do? +
An RCD that keeps tripping is detecting an earth leakage fault, which could be a sign of damaged wiring or a faulty appliance. Start by unplugging all appliances on the affected circuit, then reset the RCD. Plug each appliance back in one at a time to identify the culprit. If the RCD trips with nothing plugged in, the fault is in the fixed wiring and you need an electrician in Brough to trace and repair it.
Is a tripping circuit breaker dangerous? +
A circuit breaker that trips occasionally is doing its job — protecting you from overcurrent. However, frequent or immediate tripping indicates an underlying fault such as a short circuit, overloaded ring main, or deteriorated cable insulation. Do not simply keep resetting it, as this bypasses the protection that is keeping you safe. Have an electrician in Brough diagnose the cause before using the circuit again.
What should I do if a socket is sparking? +
Stop using the socket immediately and switch off the circuit at the consumer unit. Sparking when plugging in can sometimes be normal (a brief blue flash), but persistent sparking, blackening around the socket, or a crackling sound indicates a serious wiring fault. Do not attempt to remove the socket faceplate yourself — call a qualified electrician in Brough to inspect and repair it safely.
What should I do if I have a complete power cut in Brough? +
First, check whether your neighbours also have no power — if so, it is likely a supply fault and you should call your local distribution network operator (DNO), not an electrician. If it is only your property, check your consumer unit for tripped switches. If the main switch will not stay on, or keeps tripping immediately, do not keep resetting it — call an emergency electrician in Brough as there may be a serious fault on one of your circuits.
