Hi everyone
how can we put metal switches in a flat where there is no earth showing in the metal boxes and no earth from the light fittings in to the boxes.The fittings are earthed but we cannot get to the boxes from there. We haven't been able to check the boxes if they are earthed using the metal conduit.If they are not then can we put metal switches or not. Thanks
