Sean McD
If you must know, actually RAF. But owing to my ‘skillset’ spent about 12 years working intimately with the Army and RM (especially Bardofoss!!)
Possible issue for @Sean McD is how the 4mm transitions between floors - is it clipped direct the whole way?If clipped direct the Ref Method is C so 32A is fine. If contained in surface conduit or trunking Ref Method is B and 32A is too high.
