Hi just wondering bout a senario that i could be up against soon.
Ive to upgrade a fuse board to a new one(needs a rewire but that ll be later)
the system is TT i think after the MSF can i just use an rcd 30ma on the sockets or does the whole installation need to be protected by a certain type or size Rcd due to it being TT
Any help appreciated
