Safety precautions
Besides the protective devices, these precautions matter.
Never
- Fit a fuse wire of any rating but the circuit's 6 A or 13 A.
- Plug several appliances into one socket through a multi-plug so they draw more than it can carry.
- Push bare wires into a socket instead of a proper plug.
- Change a blown bulb in a wet place such as a bathroom without first switching off at the overload breaker or main switch.
- Handle appliances with a wet body, or touch switches with wet hands.
- Switch appliances on when the supply has failed.
Always
- Stand on a rubber mat or wear rubber slippers when ironing; a rubber mat in front of the fridge is safer too.
- Unplug appliances that are not in use.
- In heavy lightning, disconnect radios and televisions and avoid using electricity (the RCCB gives no lightning protection).
- In a fire, cut the supply at once at the overload circuit breaker.
- Have repairs and extensions done by a qualified electrician.
- Press the RCCB's test button every few days to check it works.
