Hi all, hope you can help.
I'm fitting a new light switch (metal with 3 switches). There a two 3-core cables coming into the back box, so there are two earth cores (one from each cable). One of the earth cores has snapped - I tried to extend it with a bit of new earth core and a connector block but it was already a tight squeeze getting the faceplate to go onto the back box and having the connector block in there, despite being small, is just too much - not enough room in there now for it all to squeeze in.
I would rather avoid fitting a new back box if possible (and having to hack some brick away) so my question is: do both earth cores have to be connected up to the faceplate for it to be safe (with a loop of earth going back to the box) or will just one earth core connected be alright - so the snapped one can be left out.
Sorry if it's a stupid question for more experienced people.
