[QUOTE="Doc Hudson, post: 447655, member: 1607"] Stop and have a quick think about how an external RCD'd 13A socket can protect a person using a double insulated electric hedge trimmer and they accidentally cut the flex then go and touch the live exposed wires. try and draw a sketch of the earth fault path, remembering that the supply flex is two core with no integral CPC. So if we have no CPC connected from the flex via the plug back to the earth terminal in the socket, does an RCD need a CPC through to the load for it to provide shock protection? Doc H. [/QUOTE]
