[QUOTE="Steve dandy, post: 507389, member: 33611"] I am currently installing a 3 phase supply to an outbuilding. I'm currently updating qualifications as have been out of electrical work for 10 years and have decided to return. I have a house with a 3 phase head . I propose to fit a 3 phase meter cupboard adjacent to existing 3 phase cupboard, using Henley blocks. The head is tncs. I was going to put a 3 phase switch fuse with swa underground in duct to feed 3 phase distribution board . I propose to make outbuilding tt system and use rcbos on sockets, and sauna . I was going to connect armouring at switch fuse but not at other end so the outbuilding is in its own earthing system. Is this correct? Help pls not sure if I need to 4pole rccb time delay 100ma before switch fuse to protect swa supply [/QUOTE]
