RCD Adaptor Plug (M03) | Two Wests
We strongly advise that all your outdoor appliances & installations are protected by an RCD (Residual Current Device) plug, which protects you from injury & possible death due to electrocution.
If accidental damage is done to the live wire it trips the mains supply before the electrical current through your body reaches a dangerous level.
The risk of electrocution occurs if you cut through an electrical cable, for example to your lawnmower or hedge trimmer.
