So today had a call from another contractor asking if a 3 Phase Lift Motor wired in 2.5mm on a 30A Mcb was a Code 2.
Cable undersized for fuse rating, should be 20A or cable size increased.
Now I replied it's ok from memory, having dealt with this before many moons ago, as across 2 phases 400V its 2 X 2.5mm and not a problem on 30A TP Mcb.
He felt this was incorrect.
