Shepherds hut
Former Community Member
I’ve been asked to do an Eicr on a shepherds hut and the supply to it, only had a quick look. The supply is from a farmhouse tncs earthing arrangement to a commando socket. The hut is all wood except chassis which is steel. I think it would probably fall within the definition of caravan for bs7671 so with the tncs would not meet the regs. However since the thing is entirely wood except for the chassis is there an argument for a c3 code?
If the whole structure is made of wood who cares what the chassis is made of? Just leave the chassis electrically separate from all electrical connections including bonding and it is safe. The concerns about caravans or metal mobile units is that they are mainly all metal so a connection can be made to the conducting metal caravan/mobile unit walls or door frame and Earth by people whilst entering or leaving the thing. That is why a P.M.E. supply may be dangerous as a bonded metal caravan may be at a potential above true Earth.
