Re: Earthing a part metal enclosure for mains transformer ?
There is no need to fit a socket. If it was me I would fit a 3 core flex and solder the wires live and neutral straight on the transformer and with a eye crimp on the earth wire that will fit a nut and bolt through the transformer.Make sure you scrape a little paint off on the case under the fixing screw to make sure you got a good earth connection. Ideally fit a shake proof washer.
Drill a hole through the case for the cable and fit a grommet, with a Cable tie round the cable inside to stop it pulling out or better still a small flex gland . Make sure you have a 5 amp or less fuse in the plug.
You could use chocky blocks or crimps but this way is a bit more professional.
Hope this helps Andy
