simple question,are compression coupling/connectors superior to set screw on an indoor installation.If so how?
IMO no. Steel set screw fittings are superior to compression,
But I have a hunch that ss fittings are probably installed correctly more often than comp fittings that take channel locks to tighten.
That's "schmutz." L'chaim!... or smutz ...
I'm going with no. I know the Dematic conveyor company specs comp fittings on conveyor installs because they think it provides a better grounding path?? But I have a hunch that ss fittings are probably installed correctly more often than comp fittings that take channel locks to tighten.
Comp is great for sucking a string in though, but everything else is a PIA.
That deflection, or flattening of the conduit, can make for less contact area.I don't like the way set screws abnormally deflect the pipe, especially when a helper over tightens them. But I agree comprression fittings are often tightened improperly (as well as set screw )
We're almost at an hour now, and no moderator to lock it up? :grin:
I prefer set screw personally, but have met those who feel strongly in opposition to my view.
I like the fact that the screw will pierce, or otherwise disturb any coating, or oxidation, or smutz that MIGHT some how inhibit a ground path. ( I still, with VERY few exceptions, pull in that green wire. )
My 2?
