Electrical Rewiring

Signs Your Home May Need Electrical Rewiring

Most homes in Reservoir are connected to the mains electricity supply via underground cabling. This cabling is generally made up of three insulated wires – two for the live current and one for the earth return – and usually buried in a conduit or duct to protect it from damage.

Over time, the cabling and associated fittings can degrade, which will lead to issues with the electrical supply to your house. Fortunately, there are a few telltale signs that your house may need electrical rewiring, so you can contact our trusty electricians for assistance sooner rather than later. 

1. Your fuse box or circuit breaker trips frequently

This is a sign that your electrical wiring is overloaded and could be caused by several things, such as too many appliances being plugged into one circuit or faulty wiring. 

2. Your lights are dim or flickering

A dimming light signifies that the voltage being supplied to the bulb is too low, while a brightening, flickering light indicates it’s too high. These fluctuations can cause damage your lights and other electrical appliances. 

3. Your outlets and switches are discoloured or faulty

If the outlets or switches in your home are tarnished, it’s a sign that they’ve been overheated. You may even notice charring, which is a serious fire hazard. 

4. Electrical shock

An electrical shock when touching an outlet, appliance or switch is caused by a break or loose connection in the wiring, which is extremely dangerous. 


5. Burning smells

If you smell burning near an outlet, switch, or appliance, it could be a sign of an electrical fire. This is a serious hazard, so you should evacuate the premises immediately and call the fire brigade. 


6. Your home is more than 40 years old

The average lifespan of electrical wiring is around 40 years, so if your home is older than this, it’s likely that the wiring will need to be replaced. 

7. You’re renovating your home

If you’re planning any major renovations to your home, it’s a good idea to have the electrical wiring checked and, if necessary, replaced. This is because the wiring may not be able to handle the increased demand placed on it by new appliances or additional lighting.
