Why We Need More Safety Switches in Our Homes

Why We Need More Safety Switches in Our Homes

Safety switches save lives. There’s no disputing that fact, and over the past 25 years more and more Aussie homes have been fitted with these miraculous devices. That’s the good news!

The not-so-good news, though, is that only around 65% of homes have safety switches installed today. Of those, almost none have safety switches fitted on all their circuits, with 29% only on power outlet circuits and 39% on power and light circuits. While this is a great start to thinking more safely, an electrical fault could still occur on any circuit including the lighting, power outlets, hot water, oven, stove, and air conditioning. For full protection, most homes would need to have at least four safety switches installed.

Surveys have revealed that most people believe they are well protected from electrical injury at home, but this isn’t the case when 65% of homes aren’t fully protected by the safety switches they have installed. This indicates that our wires have crossed somewhat, and we need to switch our thinking about electrical safety and safety switches.

WHAT IS A SAFETY SWITCH?

A safety switch or Residual Current Device (RCD) is a device that’s designed to cut power to an electrical circuit in a fraction of a second in the event of an electrical leakage (0.03 seconds, to be exact). The moment a circuit is detected to be leaking (as would be the case if someone touched a bare wire), the flow of electricity would be stopped in literally a heartbeat. The electrical flow is stopped so fast that the person doesn’t even have time to receive a shock, and that’s why safety switches are so important when it comes to electrical safety!

You can recognise a safety switch by the button marked ‘test’ on the front, which is what helps to distinguish it from a circuit breaker, which look similar. Many homes have circuit breakers installed, but these only protect against overloading and short circuits. It’s a good start, but not enough to protect someone from electrocution.

DIFFERENT TYPES OF SAFETY SWITCHES

There are four main types of safety switches:

  • Meter box mounted – These are mounted next to circuit breakers in the meter box or distribution board,
  • Combination safety switches and circuit breakers – These will prevent electrical shocks as well as protecting electrical circuits and appliances, and are a popular option for existing meter boxes with limited space,
  • Portable safety switches – These can be attached to a power board or extension lead to protect the appliances that are connected to them (i.e. power tools being used outdoors where they aren’t protected by a meter box safety switch), and
  • Powerpoint safety switches – These are fitted to particular powerpoints and are ideal for protecting appliances in areas such as bathrooms or workshops.

THE STATS THAT SHOW WE NEED SAFETY SWITCHES

We don’t want to resort to scare tactics, but to highlight the importance of safety switches we’ve got some statistics to prove their necessity:

  • 15 people are killed in Aussie homes every year in preventable electrical accidents where no safety switch is installed, and
  • 300 people are hospitalised every year with serious electrical injuries and burns.

There can be many different causes of electrical accidents, from a child putting a knife in a toaster to a handyman drilling through a live wire inside a wall. It could also come from a frayed cord, damaged plug, or faulty appliance. Electricity is all around us in the home, and all it takes is one small slip for it to become our enemy instead of our friend.
