Basic safety considerations
Your electricity installation needs regular testing and maintenance.
Here’s a quick checklist to get you started:
Overvoltage protective devices are obligatory to protect your property from voltage fluctuations. Surge protection devices are also advisable to protect your system from sudden voltage surges. Surges and overvoltage instances can occur when the networks distributing electricity to your property are affected by traffic accidents, lightning, strong winds, road works, construction site accidents, technical faults or other difficulties. These unexpected disturbances can damage your property’s electrical installation and the electrical devices connected to it.
An overvoltage protective device must be installed in the main distribution board in all properties, no matter how small. Surge protection devices can also be installed in your distribution board. You can also buy smaller surge protectors and install them for specific electrical devices only.
Every electrical circuit and electrical appliance (unless of the Class-II all-insulated type) in your property needs to have an adequate earthing arrangement. The earthing system makes sure that any dangerous currents caused by a fault in your electrical system or electrical appliance safely flow to the ground whilst triggering the RCD to avoid the risks of electric shock, fire or other damages. An earthing arrangement using mains water metal pipes is not adequate and not acceptable. You would need to replace it with an earth electrode system. Ask your electrician to test your electrode earthing system’s resistance and make sure it is still effective. In our climate, you may need to periodically wet the earth electrode with water to make sure it remains effective.
Do not connect multi-plug adaptors on other adaptors or extension leads. If you need additional sockets for a long period of time, consider adding new permanent ones to your existing installation. Overloading existing sockets with multi-plug adaptors and extension leads increases the risk of overheating, which may start a fire. Replace damaged extension leads immediately.
Ask your electrician to inspect and test your installation. Your electrician should provide a test certificate after each inspection and testing. It is recommended that this procedure is performed regularly. Your electrician may indicate how often your system needs to be tested, depending on the particular installation.
Make sure that you engage electricians or electrical engineers who are duly authorised to carry out electrical work on your installation.
