My father-in-law is fitting some new lights in his kitchen (metal) and tells me there is no earth supplied for one of them, he wants to carry on and fit it without using an earth !, please can you supply reasons why this is BAD! as he will not take my word for it, aside from me saying this may be fatal ! I dont know what elae to say? Maybe if he see's some responses from some qualfied sparks he will think again. Ive told him that the earth maybe cut back to the rose and maybe just a case of going back to find it but he just wants to fit the light.
