If you have recently moved into an old property, you may wish to rewire the electrical system. Older electrical systems can be dangerous as the wiring may be damaged or the fuses may be the wrong type. The easiest way to rewire your home is to ask a professional to do it. Below is a guide to the steps an electrical contractor will take when rewiring your property.

Establish the current layout of the wires

The first job that the electrical contractor will complete is to establish the current layout of the electrical wires. When you move in, you should ask the estate agent or previous homeowner if there is a wiring diagram. The wiring diagram will allow the contractor to establish the precise location of the wires. However, if this diagram has been lost, the contractor will need to trace each wire using their equipment so they can create their own wiring diagram. They will also make a new wiring diagram which details the new network of wires they plan to install.

Calculate the circuit load

The circuit load refers to the amount of electrical energy which a circuit can safely handle. Overloaded circuits can be extremely dangerous and could result in an electrical fire. The electrical contractor will be able to calculate its safe load limits by using meters which measure the resistance of each circuit.

Fit a new circuit breaker box

The circuit breaker box in your home helps protect the various electrical appliances in your home from damage while also minimising the risk of electrical fires. If there is a power surge, the breakers will trip which will isolate them from the mains power supply, protecting them from any damage. The electrical contractor will also make sure that the fuses installed in the breaker box are the correct voltage. If the voltage at which the breakers trip is too high, it may not offer the necessary protection.

Fit and test new wiring

Finally, the contractor will fit the new wiring in your home. They will then test the new wiring and electrical system to make sure it is performing as expected and that the breakers trip when they are overloaded.

If you would like to find out more about the process of installing new wiring in an old property, you should contact your local electrical contractor. An electrician will be happy to explain the process to you in more detail.
