Safety switch installation will protect you and your family
Safety Switches are the minimum Australian Standard & they can prevent fires, injuries & death!
A safety switch monitors the amount of electricity that goes into the cables that supply your light and power outlets and whatever is plugged into them.
Every 30 milliseconds it does a simple calculation that looks like this.
- HOW MUCH ELECTRICITY IS GOING IN?
ANSWER: 10 AMPS
- HOW MUCH ELECTRICITY IS COMING OUT?
ANSWER: 10 AMPS
- ARE THESE AMOUNTS EQUAL?
- RESULT DO NOTHING
This is what a safety switch does 99.9% of the time. It sits quietly in your switchboard doing maths until the day that the amount of electricity going in doesn’t match the amount of electricity coming out.
In the unlikely event that some electricity doesn’t come back after doing its job, the safety switch assumes that it has been lost in a dangerous way and cuts off further supply to that area.
In most cases the electricity is lost within an appliance or in faulty cables and no threat to life is present, however on the off chance it is lost to your hand or foot you will be glad that you had the safety switch installed.
A safety switch recognises the difference between power in and power out and “trips”, stopping the flow of current into your body. In the event of a fault like the example above, a safety switch will cut the power within 30 milliseconds. This prevents electric shock, serious injury and death. Safety switches are now a legal requirement in rental properties (along with smoke alarms) in NSW.
A safety switch can be installed in conjunction with older switchboard internals but it is more cost effective to upgrade the entire circuit protection system (switchboard upgrade).
Old style circuit breakers will limit current flow and will trip to protect the cable in your home from overheating but they aren’t designed to protect you!!!
Safety switches monitor electricity loss. If electricity leaks from the circuit a safety switch will trip. Circuit breakers and safety switches used to be 2 separate devices that were wired to work together but they have now been combined into 1 unit for ease of operation and installation. Together they protect your home and you!!!
