Hi guys,
I am helping an electrican to re-wire my two light circuits due to there being no earths. The metal back boxes are existing and fine to use but they have no earth connector in them. I normally connect to the back box earth screw and then on to the faceplate with no breaks in the earth cable. Is it safe for me to use one of the mounting screws and wrap the earth around that before re-tightening box to wall and then on to the face plate. Otherwise i need to replace about 10 backboxes and damage plaster work etc.
The earth terminals tend to be brass (is that for identification only) or should my back box screws also be brass as well if above idea is allowed?
