The Ground Pin of the power cord "OPENS" a mechanical shutter and a permits the Hot and Neutral to enter the wall socket.
Without this Ground pin (sometimes made of plastic) you cannot make any connection.

I may be missing the obvious here. I have a small UPS heading to Dubai. The requirement is for a British style fused plug. The UPS itself, is ungrounded and smack full of agency approvals. When I asked the vendor for a power cord he provided two, one with the ground pin, and the hot and neutral pins. The ground pin isn't connected to anything at the equipment end. The second configuration, and the one I anticipated getting, didn't have the ground pin on the input, or wall outlet side of the power cord. Maybe I'm missing something obvious here, but I see no application for a floating ground pin on the wall outlet side of this connector given that it isn't carried through to the equipment which it is powering? What am I missing? Gary ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
