Earthing a part metal enclosure for mains transformer ?
I need to fit this transformer in a part-metal enclosure, which I can do without difficulty. However, for safety, I want to earth it but am not in a position to cut the metal and fit a three pin socket. Would fitting a wire to one of the transformer's mounting lugs and using a 'choccy block' to connect all three wires to another three core wire be sufficient ?
