Eathing roof beams and roofing sheets on an atteached garage. Discussion ThreadEathing roof beams and roofing sheets on an atteached garage. Electrical Advice
My friend has a conundrum regarding earthing the metal parts of his garage. It's an extension to his home which is on a TT supply, It's of concrete block construction with a metal roof, attached to timbers but touching 3 RSJ's which supports the whole roof. None of which is bonded. There are tw/e cables crossing over the beams, so I suggested 10mm equipotential bonding from the beans to the MET. Question is, what needs to be done with the roofing sheets, as bonding could be problematic and cause the roof to corrode? Any ideas would be most welcome.
