[QUOTE="apprentice87, post: 388015, member: 13534"] I agree. Cannot see why the submain would need an rcd.. [unless it is fed from a TT supply perhaps] What is the earthing type of the installation feeding the submain?? Could you not do away with that, install your 100mA TD and then TT the outbuilding. Just thought that this might just give the advantage of a "standard" installation nobody can pick holes in.... But then again it is trusting protection to unreliable rcd's... john.. [/QUOTE]
