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?
However, if it is pretty much permanently in position and not likely to be transported about, then more like a mobile home [static caravan] then general rules apply.
well - are you testing the caravan - in which case you have to assume it may be moved about and could be plugged into anything, and its internal ADS etc is not reliant on the RCD at the supply end, and that a very wide range of Zs and PSSC would be OK.
Totally separately, it would be better plugged into a barn or outbuilding that is TT, or the socket that supplies it could be made more like a caravan outlet, and given its own RCD and Rod.
I’ve not tested anything yet, just a quick visual. I think there probably won’t be continuity to earth from the chassis due to rubber tyres on the concrete. If they do any remedials as a result of my it won’t be me doing it, I’ve just been asked for the eicr. As it stands it doesn’t look more dangerous to me than a garden shed so it would seem overzealous to give it a c2 even though it does not comply with bs7671. Am I being too lenient in my thinking?
If the structure is plugged into a socket is it just an "appliance" and not fixed wiring?
Z.
But if that argument worked, then you could make the same case for a caravan.
Is the structure a caravan? It sounds more more like a wooden shed on wheels. Is it an office or a playhouse for children, or does a shepherd live in it surrounded by sheep? BS 7671 defines a caravan as "A TRAILER LEISURE ACCOMMODATION VEHICLE, USED FOR TOURING, DESIGNED TO MEET THE REQUIREMENTS FOR THE CONSTRUCTION AND USE OF ROAD VEHICLES (SEE ALSO DEFINITIONS OF MOTOR CARAVAN AND LEISURE ACCOMMODATION VEHICLE)" It may of course be a mobile transportable unit as others have suggested. (Section 717).
Or it may be a static unit with wheels just for effect, or to overcome building regulations covering permanent static outbuildings.
