Loss of Light or Power

Fuse or trip switch

Check your consumer unit or fuse box: it will either have fuses or trip switches. Modern electric circuits are fitted with a circuit breaker fuse system: if a fault develops, a switch is tripped and the circuit is broken. Older ones have fuse holders and when the fuse is blown it must either be replaced, or rewired using special fuse wire of the correct amperage. Only replace a fuse if you are confident you can do it safely, and have a replacement of the same amperage. If in doubt contact us or a qualified electrician.

Setting a trip switch

Open the cover on the consumer unit to expose the trip switches. The consumer unit is usually next to the electricity meter. Check which switches have tripped to the OFF position and put them back to the ON position. For more detail, refer to any handbook supplied.

If tripping occurs again

It is probably being caused by a faulty appliance. You need to identify which circuit is affected and which appliance on that circuit is causing a problem.

Which appliance is faulty?

Go around the house noting which set of lights or sockets are not working. Unplug all appliances on that problem circuit and switch off the immersion heater. Switch the tripped switch to the ON position and plug in the appliances one by one until the trip goes again. Leave that appliance unplugged. If one of our appliances is at fault, report the repair; otherwise get it fixed yourself by a qualified electrician or service engineer.

What causes it to trip or blow a fuse?

  • An overloaded circuit.
  • Too many appliances being used at the same time.
  • A faulty or misused appliance.
  • Overfilled kettles.
  • Unclean toasters.
  • Cooker rings worn out or cracked.
  • Faulty immersion heaters.
  • Faulty connections on leads to appliances e.g. hi-fi, TV, etc.
  • Light bulbs blowing.

Plugs

The socket outlets in your home will take square pin plugs. The plug which you require will have a fuse inside it. We do not supply plugs and you will have to obtain them yourself. To find out the correct type of fuse to fit in a plug check the rating plate on the appliance, do not overload plug sockets by using multiple plug adaptors.

Warning

  • Never tamper with the electricity company’s fuse and seals.
  • Never take any action unless you are confident you can do it safely.
