Steel Conduit

[Pete999]

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.

I'd like a nice conduit job to get on with, did loads when I was a young fella and loved it but haven't touched steel conduit or trunking for probably 20 years now.

Trouble is when the original is done to such a high standard as you all did, it is a permanent fixture so will not be replace by tray or ladder. The singles can be added to and taken away . Unless IP containment is needed for hazardous atmospheres then tray, metal box or similar would be cheaper and less labour intensive. I'm training so can't wait until I need to do some. Plastic conduit is fun but comparison to Lego building. I want meccano, metal meccano!

I have always run in a cpc purely because of spec, remember red oxidizing the joints before the pure of cement.

The "surveyor'' a term i use loosely at my place only quotes plastic conduit for everything. As metal takes too much time and expense. Really annoys me as in some scenario's like fabrication shops i feel metal is best suited to the environment. Shame really the art of it is dying out, i love metal trunking and conduit.

I've just run 150 meters of 20mm galv around the circumference of a silo for lighting. Nothing beats metal IMO.

I'm still a youngster and can metal munch to a very high standard even if I do say myself Talking of continuity of steel conduit would you trust this conlok carp....I know I wouldn't.

Cowboy boxes more like, getting more like the septics every year.

Speaking as a non sparky here obviously, but if you screw the boxes to the wall, surely in theory even a grub screw is only a backup? As the conduit won't come off without unscrewing the box to allow for movement?

Or do they not get screwed to the wall all the time?
