Does SWA need RCD on a TT? Discussion ThreadDoes SWA need RCD on a TT? Electrical Advice
I know the answer, at least I think I do as I am now questioning myself! It's just I've seen a few jobs recently where the electrician (or who ever did the job) did not give any fault protection to the armoured cable, so I am wondering if I am missing something?
The most recent example from today is an EVCP which has been installed using SWA cable. The SWA goes directly into the consumer unit where it is supplied from a MCB. There is no relevant RCD protection on this cable. I realise it would not be required for TNCS or TNS as it would have fault protection from the main fuse. However, this is a TT, so there will be no fault protection on the SWA cable.
This is clearly wrong, isn't it?
