Generator powered installation within a house with mains supply?

Daniel Vincent Hale

I have been asked to advise on if it is possible to use a generator to power a small temporary installation within a building with mains supply. The temporary installation would be isolated from the mains supply via use of safe distance and physical barriers. There would be no possibility of equipment being plugged into both power supplies. Does anyone have any advice on this?

    Earthing (or bonding at least) would likely need to be common for the building and generator. (unless the two installations, including all extraneous-conductive-parts, were out of reach of each other, including any portable equipment)

    If ADS is used, BS 7671 actually requires this. See Regulation 411.3.1.1
