As I've said, if there are not good screwed connections throughout the conduit system, then you risk not having any form of fault protection on section(s) of conduit containing singles.
Securespark's old method sounds foolproof, it's a shame it is not considered normal practice today.
I wonder how many steel conduit systems are thrown together and hand tightened with poor joints on the wrong assumption that a separate cpc will allow the attainment of all the requirements.
