    [Question] Earthing a metal back box

    I am replacing a 4 x 4 double socket in my home. The back box is metal. Is it legal to secure the earth conductor to one of the mouting holes in order to earth the box? If not, how would you go about earthing the box if the box itself doesn't have an earth terminal?

    I usually use a tech screw into the back of the box and a lead with a crimped on lug.
