Circuit breakers, surge protectors and RCDs
Further information:
- Circuit breakers, surge protectors and RCDs
- Types of RCDs
Circuit breakers and fuses are designed to protect electrical cables and fittings installed in the home from overloading and short circuits. They cut the power when electrical wiring in the home has too much current flowing through it. They are designed to prevent electrical fires, not electrocution.
Some meter boxes have surge protectors fitted to safeguard appliances against a spike in electrical voltage, such as a lightning strike. Some power boards or extension leads also have surge protectors fitted. These devices do not offer any protection against electrocution.
Only RCDs will prevent electrocution by cutting the power to a circuit in the event of an earth leakage.
RCDs are the only device that can give you or a family member a second chance.
