How to Identify Electrical Faults

Electrical faults can be difficult to pinpoint, especially if you don’t know what to look out for. Not to worry! Rolly’s Electrical is equipped with years of expertise and knowledge to ensure that it helps you keep safe and vigilant in your home. Here are some common faults that you may run into and how to detect them.

Tripping Circuit Breakers

One of the most common reasons why your circuit breaker is tripping can be overloading powerboards. To prevent this from happening we recommend that you spread your electrical devices throughout the home, so you’re not burdening a single circuit. 

It’s also a good idea to investigate what appliance you were using when the circuit tripped. If you were using an item with a high wattage like a microwave or hairdryer, you may want to try using a lower setting. Otherwise, you should consider limiting your electrical usage on the circuit when using high wattage appliances. 

Light Bulbs that keep burning out

If you’re finding that your light bulbs are burning out frequently, then this is a good sign that something isn’t right. There are several reasons why this may be happening including the wattage being too high, insulation being too close to the light, poor wiring on the circuit, poor wiring on the mains, or poor connection on the circuit. 

This issue can be quite difficult to navigate for non-professionals, so we do encourage you to contact us so we can get to the root of the problem.

Lights Being Too Bright or Dim

You might find that some lights around your house seem overly bright but others are dim, then there are a few reasons why. Firstly, the lights in your home may have different wattage, so it’s a good idea to check that the globes are identical. Secondly, you may have a poor main neutral connection, which will continue to cause issues for you if not fixed by a professional. 

Constant Electrical Surges

Surges in the home can be triggered by a number of things including lighting storms, damaged power lines, faulty appliances and poor electrical wiring in your home.

Generally, an actual surge will only last for about a second or so. However, frequent surges can damage the electrical components, which can severely degrade their life expectancy. 

If you’re encountering this issue then an electrical device connected to your home grid or the wiring in your home is to blame. 

If you’re unsure about how to proceed in this situation, it’s time to consult with a qualified electrician. 

Unusually High Electric Bill 

Does your electric bill have you scratching your head? Well, electrical faults around your home may be to blame. 

Here are a few helpful tips that can help you lower that hefty bill. Firstly, identify and update any devices that are creating power surges in the home. Secondly, unplug devices and appliances that are not in use. Finally, make sure your electrical wiring is up to date.
