R.C.D.

A residual-current device (RCD), similar to a residual current circuit breaker (RCCB), (formerly known as an Earth leakage circuit breaker or ELCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor.

Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions.

An RCD is a life-saving device that protects against dangerous electric shock and reduces the risk of electrical fires.

Fit an RCD in your fusebox - this will give the highest level of protection to your family and home as covers all wiring, sockets and appliances on a circuit

Plug-in RCD - can be plugged into any socket and will protect you if a problem arises when using a particular appliance. They are available from most home-improvement stores and garden centres.

Why haven't we heard about RCDs until now?

In a recent survey a third of respondents said they knew what an RCD was – however, we know that many people confuse them with circuit breakers, which offer nowhere near the same level of safety protection.

RCD protection will switch off the electricity in a fraction of a second if you get an electric shock. Having a modern consumer unit fitted with RCDs gives you the best protection because they usually cover all the wiring, sockets and appliances in your home. Check whether your consumer unit has RCD protection by looking for the ‘T’ button and label stating ‘test quarterly’. If it has these, it’s likely you’re already protected.

If you don’t have RCD protection, ask me for a quote.

Like a smoke detector, it could save your life.

If your electrics trip frequently it probably means you have a faulty appliance or wiring.
