Faulty Wiring – 6 Tell-Tale Signs

faulty wiring – 6 tell tale signs

Faulty wiring is more than just an inconvenience for your business. It poses a serious health and safety risk to everyone and everything on site. At the very least, wiring faults can lead to small electrical shocks. In the worst case scenario, they can lead to fire outbreaks and even cause fatal harm.

Either way, it’s not something you should put up with. In this post, we’ll outline some potential causes of faulty wiring and how to spot it on your premises.

What’s behind faulty wiring?

As the name suggests, faulty wiring often arises from poor workmanship. Electricians that aren’t properly trained, accredited or experienced will make errors which cause big problems down the line – long after they’re gone.

To avoid this going forward, you’ll want a local contractor that’s worth their salt. That’s covered in our guide on how to find the best commercial electrical contractors, including:

  • Accreditations – Look for names like NICEIC and SafeContractor.
  • Experience – 5-10 years’ experience is a good trust factor.
  • Reviews – Check reviews on Facebook and Google.
  • Expertise – Make sure they offer the specific services you need.

Even if you only work with the best of the best, you can still fall victim to faulty wiring. Your business might have moved into a new premises. Or maybe the wiring job was overseen by a previous site manager who was a little less cautious.

Of course, there’s always the issue of time. Wiring can be subject to general wear and tear, or can even become outdated as new practices and materials take over. That’s why it’s important to have your wiring regularly inspected.

Signs of faulty wiring

Without further ado, let’s take a look at some signs of faulty wiring on your premises…

1. Buzzing

It’s easy to assume that any buzzing noise you hear is simply the sound of electricity. However, well installed wiring shouldn’t actually make a sound you can hear. Faulty wiring can cause the buzzing sound and could be allowing current to escape.

2. Smell

Likewise, electricity doesn’t (or shouldn’t) have an odour. If you can smell anything odd around your sockets, switches or consumer unit, you should get it seen to immediately.

3. Flickering lights

Lights can obviously flicker if they need replacing. But if that doesn’t fix the problem, it’s probably a sign of faulty wiring. That could be down to large appliances dominating your circuit, for example.

4. Heat

Whether it’s a large powerful appliance or something that’s actually intended to heat things up, the socket itself should never become hot. Whatever you’ve plugged in, check for heat around the socket or outlet and get any issues inspected.

5. Frequent circuit breaks

Circuit breakers are installed as standard to stop electricity flowing when a problem is detected – including an excess of current or a faulty component. That could be down to overloading or a defective appliance. However, if you notice that they’re constantly tripping, it could also be a sign of faulty wiring.

6. Shocks or sparks

While these two sound obvious, they’re still worth mentioning. Sparks around sockets or switches –or shocks when using them – are clearly a sign of faulty wiring, or at the very least a faulty appliance.
