when running SWA from a metal clad housing to another when the SWA is 10mm and on a TN-S system...would you..
a) Use 3 core and use one as an earth as well as the armouring?
b) don't use the 3rd core and just use the SWA armouring?
something rings a bell from the regs stating that option A is a no go..but not having it to hand right now, i thought id ask.
what does everyone think - appologies if this has been asked before - i dont have time to go through page after page after page of previous topics.
cheers
