HELP! My Electrics Keeps Tripping

Categories: Electrical Contractors

Why does my electrics keep tripping??

Question: Why is it every time I turn my shower on, my electrics go off? I need a shower!!

Questions & Answers: How old is your fuse box? Would it be the Old Wylex (or other branded) box?

Although these old Wylex fuseboxes are well designed and made the design is no longer suited to modern installations. The main drawbacks are no facility to fit RCDs, and most of them are limited to 30A per circuit.

It’s time to upgrade to a more modern fixed RCD fuse install. I can upgrade your mains distribution for a fixed affordable price.  If you have a replacement mains board then it must be accompanied with an Electrical Completion certificate. This will have a schedule of inspections & a scheduled test results along with a front page that the Inspector signs.

What’s an RCD? (Residual Current Device)

An RCD is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock. In other words, it’s a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. An RCD constantly monitors the electric current flowing through one or more circuits. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, the RCD will switch the circuit off very quickly, normally within a few milliseconds, significantly reducing the risk of death or very serious injury.

old set up

The photo (not taken by me) above is an old electrical setup. These older boxes were made with no back and normally on a wooden frame. In almost all cases the wooden frame is flammable, and since fuseboxes are often mounted on wooden boards, the backless types are dry kindling waiting to be set on fire.

Having a high current appliance such as a 12kW shower to one of these old fuseboxes results in various failures such as

1, Tripping electrics
2. The fuse contacts overheat.
3. The plastic holding the contacts becomes discoloured and brittle.
4. The loose contacts eventually spot-weld to the fuse carrier.

I already have the new modern boxes, but still, my electrics go off!!??

There are a few reasons that an RCD may trip, you have a faulty appliance plugged into a socket. This is probably the number one reason that an RCD will operate and can be tracked down by noting if you have just operated an appliance when it tripped. Common causes are irons, cookers, kettles and fridges.

How to fix it? 

1, Turn off all the circuits that are protected by the device and try to reset it. If it stays set, you can then turn on each circuit one by one.

2, If it stays set, you can then turn on each circuit one by one.
