Don’t be shocked! The hidden electrical hazards in your home

Remember when a home's electrical demands meant a TV, a kettle, and maybe an electric blanket in winter? These days, the average Kiwi household is running multiple computers, gaming systems, smart devices, security cameras, phone chargers in every room, and maybe even an electric vehicle charger in the garage. Yet most of our homes still have the same electrical systems they had 25 years ago. Talk about electrical hazards...

Last month, No Shock was called out to a Mount Eden family whose 'home office' consisted of two daisy-chained multi-boards powering a laptop, monitor, printer, phone charger, and a gaming setup. It had been fine for years – until it wasn't. The burning smell was their first warning that something was wrong.

Fortunately, it had been spotted early, and no major damage was done – but if it had happened when no one was at home, the possibility of a house fire was all too real. Our electrician sorted out the problem by initially installing more sockets and then returning later that week to install a new switchboard with Residual Current Devices (RCDs) to protect the electrical system – and you! If there is a wiring fault or a wire accidentally becomes exposed, the RCD will automatically switch off the circuit, preventing you from injury.

Let's start with what we call 'The Multi-Board Mayhem'. A powerpoint is only designed to fit one plug for each socket. When you add multi-boards, you're overloading what that socket is designed to handle. We see it all the time – power boards plugged into power boards, often hidden behind furniture where heat can't ventilate out properly.

Then there's the charging challenge. Those innocent-looking phone chargers and battery packs left plugged in? They're a bigger fire risk than you might think. Even when not charging, they can overheat. And don't forget about those devices charging in the garage – lithium batteries are particularly risky if left charging for extended periods.

The standby power trap also catches many people out. TVs, monitors, computers—anything with a little standby light is still consuming energy and potentially creating risk. A firefighter told us that one of the biggest causes of house fires these days is appliances left on standby. It's not just about wasted electricity; it's about the constant heat generation in your walls.

Smart solutions for modern homessmart home devices

Today's homes are packed with more electronics than ever before, but there are smart ways to manage them safely. Consider installing dedicated USB outlets in key areas instead of using multiple chargers. Set up proper charging stations away from flammable materials. And think about smart switches that can be controlled remotely – they're great for both safety and energy saving.

When it comes to protecting expensive electronics, surge protection isn't just an optional extra, it's like insurance for your electronics. This is particularly crucial if you work from home, have gaming systems, or live in an area prone to lightning strikes.

Warning signs you can't ignore:

  • Burning smells (especially from power points or walls).
  • Circuit breakers that keep tripping.
  • Warm or discoloured power points.
  • Flickering lights.
  • Strange buzzing sounds from electrical points.

If you notice any of these signs, don't wait. And definitely don't let your DIY-enthusiastic relative convince you they can fix it – electrical work isn't a weekend project for untrained electricians.

What to do in an electrical emergency

If you do encounter an electrical emergency, turn off the power at the switchboard if it's safe to do so. If you suspect fire, get everyone out of the house. And call emergency services if needed. We've seen too many small problems turn into big ones because people hesitate to call for help.

The bottom line

Modern homes need modern solutions. Regular electrical checks, especially in older homes, can identify hazards and catch problems before they start. Upgrading old wiring, installing RCDs (Residual Current Devices), and investing in quality electrical equipment might seem expensive, but it's nothing compared to the cost of electrical damage – or worse. Remember, electrical safety isn't just about avoiding shocks – it's about protecting your home, your expensive electronics, and most importantly, you and your family. The cost of prevention is always less than the cost of cure, especially when it comes to electrical issues.

Need an electrical safety check? Want to upgrade your home's electrical system? Don't wait for that burning smell to appear. Contact No Shock Electrical for a thorough inspection. After all, the only shocking thing in your home should be your teenager's taste in music!
