RCD’s (Residual Current Devices) can respond to changes in the flow of electric current.
For example, when a flex or cable is cut, or an electric tool malfunctions and direct contact is made with a mains supply conductor and earth, the RCD automatically disconnects the power supply to the equipment to reduce the risk of you being electrocuted.
RCD’s are available in several forms:
- as portable adaptors
- incorporated in socket outlets
- as separate stand alone units for fixed wiring installations offering whole house protection
- as modular units for use in household consumer units
However, although RCD’s are a vital safety aid, they can’t guarantee 100% protection. Even with them in your home, isn’t it better to make a long term investment in good safety practice by looking after appliances such as hedge cutters, hedge trimmers, chainsaws, drills and sanders.
