Hi, i am after a bit of advice. I went to a property which had 3 outbuilding, all were separate from the main building, one garage, one shed, & a workshop. Circuits all supplied from main building. Earthing system is TT. In all of the 3 outbuilding there is a separate water supply with metallic pipes. There is one socket outlet & one light in each building.
My question is, should these pipes be supplementary bonded? or would they need m.p.b to the MET.
cheers
