Electrical Fault Finding

Before you call PB electrics there are a number of common causes of electrical faults so we’ve provided an overview of the most likely causes. Work your way through these troubleshooting steps to see what your problem is likely to be. But remember, it’s always best to call in a qualified electrician to carry out the actual repair. With PB Electrics ther is no-call-out charge and all our estimates are FREE.

Blown fuse in the fuse board or consumer unit
If wires in your home or appliances overload the wiring or a fault occurs resulting in a short circuit , you are protected by either fuses or circuit breakers at the consumer unit that cut off the power as soon as the overload or short circuit is detected.

Normally there is a separate circuit for the downstairs sockets, downstairs lighting, upstairs sockets and upstairs lighting. There are almost always extra circuits to protect bathroom electrics and other appliances.

Older fuse board systems use fusewire that melts, this must be replaced by new fuse wire of the same rating after you have dealt with the cause of the fault. See our examples of fuse boards types if you are not sure.

Newer fuse board systems use small circuit breakers that trip when overloaded or a short circuit occurs. They are reset by either pushing in a button or flipping a switch. Again, always deal with the cause of the problem or call in a qualified electrician.

Check the individual circuit
If a fuse or circuit breaker does cut off the power, it may be that there are too many appliances on that circuit or that the load is too great.

Take out the fuse or leave the circuit breaker in the off position while you check the circuit. Try unplugging one appliance at a time and switching the power back on to discover if one item is overloading the circuit. If you can’t find the source of the problem, call PB Electrics on 07810 792066

Faulty switch or socket
Sockets and switches should always be replaced if they are cracked or damaged in any way. You should also look out for any black deposits that indicate a faulty connection. If you are unsure then contact PB Electrics.
