Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This Question of the Day, concerning metal socket back boxes and earthing requirements, is answered by the ECA:
Question: I have been told that metal socket back boxes (plastic socket fronts) no longer require earthing. Is this correct?
Answer: The ECA recommendation is that metal back boxes should be earthed. However, the IEE guidance notes state that if the metal back box has at least one 'fixed' front plate fixing lug, then they do not need to be earthed.
