[QUOTE="SPECIAL LOCATION, post: 79983, member: 250"] "[I]or is it a case of TT everything that is outside the equipotential zone"[/I] No IMHO that is definitely not the mindset to approach it by! you need to ask yourself a couple o basic q's 1/ what is the construction of the outbuilding/garage? a) Brick / wood (Nonconducting!) B) Metal frame prefabricate jobbie..... c) Maybe some parts are conducting & could introduce and earth potential? 2/ Are there any incoming gas / water / oil pipes that could introduce and earth potential? If possibility of earths and/or loadsa metal bits I would probably TT! If non condcuting... short run (10m <) export supply from House (inc earth)! [/QUOTE]
