Hi there
I a question which is vexing me relating to an outbuilding and I can't suss it our from the regs (16th edition block!)
When replacing a consumer unit and putting in a couple of radials in the outbuilding recently I found when I opened the existing CU that the armoured cable was only delivering live and neutral from the house main CU.
The set up is that the house has TT earth and mcb fusebox which seems to all be overidden by an RCD conveniently situated in the house where it is easily reset (it often trips apparantly).
The outbuilding cct is run from a 30amp mcb at source and is buried underground until it appears at the outbuilding.
My question is should I install a separate TT earth for the outbuilding or have I missed something and this is all Ok (By the way the cu I installed has a 30MA main switch with an mcb for each circuit.
many thanks
