I was wondering last night, or should I say wandering, when I were a Lad working with steel and Galv conduit, I distinctly recall the Electricians I was working with always gad me filing the ends of couplers, locknuts etc and also removing the pain from entries into steel enclosures, I know in those days we normally used the conduit as the cpc.
Is this practice still in use, or do you just bung in an earth conductor to be sure of a decent continuity reading.
