Don’t be tempted to do your own electrical work – it’s illegal and it can also be deadly.
If you are planning to have some electrical installation work done, you must engage a registered electrical contractor such as SEM. They will dispatch a licensed and qualified electrician to do the work to the required standards.
Safety switches, surge diverters and circuit breakers
Safety switches are often confused with circuit breakers and surge diverters. Safety switches are not the same as circuit breakers or fuses. Safety switches are designed to prevent injury or death by automatically switching off the electricity supply, within 0.03 of a second, when an electrical fault is detected.
Safety switches are an additional form of protection to be used with circuit breakers and fuses. They may not protect all wiring and electrical appliances and will not prevent all electric shocks. Fuses and circuit breakers protect against short circuits and current overloads.
It is important to understand the differences between these three devices.
What’s the difference?
Surge diverters and circuit breakers do not act as safety switches for personal protection against electric shock.
Safety switches are not a substitute for common sense!
If you are unsure if a safety switch is installed at your property, contact a registered electrical contractor. Here's how to contact Michael at SEM...click here
Switches, power points and power boards
If you are unsure about switches, power points or extension cords at your place...contact SEM here...don't risk you or your family's safety.
Approved electrical appliances
All prescribed electrical appliances and equipment must be approved prior to being made available for supply. Approved electrical appliances display a regulatory compliance mark (RCM) or a unique safety approval number.
Approval markings can vary between states. Typically they are an alphanumeric code, comprising the first letter of the state that issued the approval followed by between one and six digits.

Monitor the flow of electricity through a circuit and detect a problem that may pose a risk to personal safety and turn the power off within 0.03 of a second, and always have a test button and 30ma printed on them. They are also sometimes labeled with the words “safety switch”.
Protect the property from voltage surges such as those resulting from a lightning strike. The surge diverter captures the voltage spikes in the wiring that would otherwise be transferred into the equipment within the property.
Provide short-circuit and overcurrent protection such as when a power point is overloaded.
