Had a three phase set and neutral conductors (120mm).. I was cutting out the holes on the gland plate etc 32mm for each conductor, 25mm for earth..one of the other sparkies said as the gland plate was steel not alluminium I would need to cut links between all of the holes in order to reduce inductance... Never came across that one before... Maybe if the glands were metal I would have seen some method to his magners but I couldn't... Anyway if someone could put me out my misery it would be appreciated thanks..
