What is a safety switch?
As their name suggests, safety switches are designed to prevent injury or death from contact with an electrical current.
How do they work?
It is important to note that a circuit breaker is not the same as a safety switch. Circuit breakers and fuses serve to protect appliances – not people – from an electric shock. Safety switches are different, as they cut power in the event of earth leakage, thus protecting people from injury.
If an electrical circuit is compromised, a safety switch detects a loss of current and cuts the supply of electricity to the circuit in around 30 milliseconds. This is faster than the full completion of a heartbeat, and as a result, a safety switch significantly reduces the risk of cardiac arrest.
Should I install safety switch?
In an ideal world, everyone would have safety switches. With their ability to save lives, they are an invaluable investment. However, some homes and businesses have a greater requirement for them.
Your safety switch requirements depend on the amount of electricity your business or home uses. If you are unsure about whether you need safety switches installed, or want to know what your requirements are, speak to Gangi Electrics today.
Emergency & Exit Lighting
Do I need it?
The requirements for emergency and exit lighting are dictated by the Building Code of Australia (BCA). Section E, Part E4 outlines the various requirements that buildings must satisfy. If you’re unsure whether you fit within the parameters set out there, it’s best to talk to someone well-versed in the legislation, such as a lawyer or building inspector.
How do I meet the legislative requirements?
Our aim on this page is to give a general idea of how the sections work. For a proper understanding of what your obligations are, it is integral to consult the actual sections of the BCA.
Section E4.2 lists the requirements for emergency lighting. Broadly speaking, the amount of lighting needed depends on the floor space of the building, the existence of stairwells and passageways, public access, changes in floor height and what the building is used for.
Exit signs are legislated under section E4.5. These requirements are less dependent on the size of the building. Instead (and unsurprisingly) the positioning and number of lights are dictated by the buildings exits.
If you need more information, feel free to give us a call. Our experienced Melbourne electricians will ensure that you meet the requirements.
