Regarding PVC coated galv. I know spec determines but when running interior and terminating into a large pullbox or switchboard what are the diiferent or most common terminating methods you can use? I'm aware of the following. Thanks.

1. A hub.
2. Locknut and bushing
 
I've never had a pullbox when using PVC coated. What can of box does one use ? You would assume it needs to be non-corrosive, perhaps non-metallic ? If they spec PVC coated they should spec the pullbox material based on the environment.

True. We've been using the 10 ton Milwaukee 10 Cordless knock-out punch and it's rated up to 14 gauge stainless steel so on a typical pull box it works. Not sure how long the dies will last when compared to mild steel pull boxes.

#2 would pretty much completely defeat the purpose of using PVC coated rigid.
The PVC coated conduit hub will be expensive.
