Fuse Board Replacement Edinburgh

Fuse Boxes Explained

Your fuse box (aka consumer unit) is usually quite easy to find in your property. If you don’t already know where it is in your property, then make sure you find out. If you ever have an emergency and need to shut off your electricity, this is where you do it from.

A fuse box is usually comprised of three things which are used to regulate and provide the electricity throughout your property. These three parts are the main switch, residual

current devices and fuses/circuit breakers.

Mains Switch

The mains switch enables you to turn off the electricity supply to your property.


Fuses/Circuit Breakers

Circuit breakers are found in the fuse box, they are designed to protect from electrical surges by turning off a circuit when a fault is detected. Circuit breakers provide more accurate protection than fuses, and when they switch off, you just need to find the circuit breaker that has tripped and switch it back on.

Fuses do the same job as circuit breakers, just in a slightly different fashion. They have a thin piece of wire which is connected to two screws. When there is a fault that causes a surge, the piece of wire will overheat and eventually melt. This results in the circuit being broken and disconnecting.

Note: Whether your fuse box uses circuit breakers or fuses, always make sure that you investigate what caused the fault and have it corrected before replacing the fuses or turning the circuit breaker back on.

Residual Current Devices (RCD)

RCDs are switches that will turn off a circuit when it detects dangerous conditions. This will result in the electricity being disconnected. If you have multiple RCDs in your property, be sure to test them on a frequent basis.

Testing them is easy; there will be a button which says either ‘T’ or ‘Test’. Every few months you just need to push the button. Once you push the button it should turn off all the electricity to the property. If that happens then just switch it back on to return the electricity to your property.

However, if the electricity doesn’t come back on, this means there may be a problem. In this scenario you should contact a qualified electrician immediately to come and investigate the problem.

Upgrading your fuse board

Due to current regulations, a lot of people will have to upgrade their old fuse board to a modern one which two RCDs in place. It is usually cheaper to simply upgrade your current fuse board than have a new one installed.

If you do decide to have a new fuse board fitted instead of upgrading the current one, it might carry additional costs for electrical work. This could be due to there being a requirement to run new cable, splitting the circuits that are already in situ and/or alleviating borrowed neutrals problems by having to lay a new cable back to the fuse board.

Installing your new fuse board

This involves turning off the overload protection and setting up a new system for basic and fault protection, which will result in the electrician having worked on all your circuits.

This means the electrician will have to carry out a full electrical test on all these circuits to check they are safe, he’ll then provide you with and electrical installation certificate before the work is completed. Before the circuit can be energised, any problems that are found while carrying out the electrical test will have to be fixed.

Be Safe

If you are thinking of doing this work yourself, always be sure to isolate the circuit and lock it off. Place a sign next to the isolation point letting people know that work is being undertaken and that the power should not be turned back on.

If you don’t feel totally confident doing the replacement yourself, you should seek the help of a qualified electrician. With building standards becoming more stringent all the time and a lot of work having to be run by your local authority, it might be more costly in the long run if you have to have mistakes fixed by a professional.

Another issue to consider is that if the worst did happen, and you modified the electrical installation in your home by yourself and it resulted in a major fault, then it is likely that it could make your home insurance invalid.
