Hi I know this is going to seem a little daft asking this but here goes anyway. I went to change the old isolater switch for the cooker today and upon opening and observing the scrappy wiring job I realised the new 40A switch I had purchased doesn't have any place to wire in the earth like the old one. The old one is wired to the metal plate. Is it safe to leave the earth off and just wire the two sets of lives and neutrals or should I get an isolator with a metal plate.
Appreciate a little guidance. Ok so I'm not an electrician but I don't normally run into these sort of issues can anyone advise other than getting in an electrician please?
