Frequently asked questions
Still unsure? Call 01204 952 628. We're happy to talk it through, no obligation.
Why does my RCD keep tripping?
Usually an appliance with an earth fault, moisture in an outdoor fitting or a damaged cable. Unplug everything on that circuit, reset, then plug things back in one at a time.
Is it safe to reset a breaker?
Once, yes, if there's no smell of burning, no damage and nothing wet. If it trips again straight away, leave it off and call an electrician.
What's the difference between an RCD and an MCB?
An MCB protects a single circuit from overload. An RCD protects a group of circuits from earth leakage, the kind of fault that causes electric shocks.
