How to resolve a tripping fuse box Home Rewires

A fuse box that keeps tripping indicates that you have a faulty electrical item or faulty wiring somewhere in your home. Working out what is wrong is largely a process of elimination, and you can usually narrow down the problem yourself. Our latest article on how to resolve a tripping fuse box looks at possible problems and explains at what point you may have to call an electrician in.

Are you overloading your circuits?

Electric circuit overloads are a major cause of house fires so it’s crucial to be alert to the warning signs and know how to manage your homes power consumption. Circuits can only cope with a limited amount of electricity and overload happens when you draw more electricity than a circuit can safely handle – by having too many things running on one circuit. Electrical Code safety regulations say you can load a circuit up to 80 percent of its amperage rating. For instance, a 20-amp breaker will trip if it draws 16 amps of power. Keeping below the 80 percent figure will avoid overloads. If you rely on heavy use of extension cords, for instance, it suggests you don’t have enough outlets for your needs, and a qualified electrician can inspect your home and add new outlets.

Do you have a faulty electrical appliance?

Unplug every appliance and fitting in the room, switch the electricity supply back on, and then methodically go around the room plugging things in until the RCD trips. Bear in mind that one of your electric appliances or fittings is faulty and could be dangerous, and although your RCD should protect you, this is not guaranteed. If just one item is affected, then this item likely has a broken plug fuse or has malfunctioned. If the fuse has blown, then replace the fuse. If the appliance is faulty or malfunctioning, then get it repaired or replaced.

Do you have a wiring fault?

This is the point when you need to call out a domestic electrician. As resourceful as we all try to be, a professional needs to take look at this, as it is beyond most of our capabilities. All appliances in your home can wear out or develop a fault and circuit breakers are no different. Warning signs of a faulty circuit breaker include:-

  • The main breaker is tripping, but the individual breakers are fine
  • The breaker won’t stay reset
  • A burning smell in the electrical box-A circuit breaker that keeps tripping frequently
  • Signs of damage to a breaker, like scorch marks

If your consumer unit is old (if you still have a fuse box then it’s old) or your electrical panel hasn’t been serviced in the last five years, you need to consider having it repaired or replaced.
If you are not experienced and knowledgeable in repairing the electrical problems you are having, it is best to hire someone who is. And, with the certifications they should have, you will be able to rest easy knowing that the repair work has been carried out to a legally sufficient standard.
