Does it need rcd protection, if the circuit is MICC throughout it probably doesn't need it.

It may not (or it may, depending on what/where it is), but that's certainly no reason to swap it for a circuit breaker and leave the fault in place!

Hmm... Somebody must have posted earlier and the post deleted. I certainly didn't go digging up old threads!
