Oh, i have no idea, sounds like he's just a commercial guru, they get tunnel vision on other wiring methods outside of the commercial atmosphere...

Metal is better in case someone slops some paint on a ground screw. I guess.

And there's nothing particularly wrong with that

I was just curious.

i know, but when someone is fixated on how they do things, they bring to much opinion into what is required, sometimes it can cost someone money they didnt need to spend on doing a job.

I don't get it. I'm not trying to be smart, I just don't know what you're getting at.

Very true. I haven't compared prices on conduit in a long time, but if you're working for someone else, insisting on conduit that costs (let's say...throwing out a number) twice as much could cost you the job. (Not talking as an employee...but as a contractor working for a customer)

I was strictly talking about the normal 15, 20 or 25 amp lighting and outlet type circuits which use standard 10, 12 or 14 ga wire, not industrial applications!
Sorry if I wasn't clear on that but the thread was about the OP's normal non industrial wiring and that was what I had in mind.

Just so you understand my point, i'm not against you in favor of pulling in an EGC, but if someone asks if it is required, you have to just say "no" and let the installer make the decision... saying its better to pull a EGC is just a false statement. Hope thats respectful enough.

why would you not use PVC conduit?
The better question is, why would you put matches next to a gasoline can?

Plastic burns, it also gets brittle over time, it has no grounding ability either.
I don't trust plastic.

I was being sarcastic, based on "With the separate green grounding wire, the metal conduit still acts in the capacity of a redundent ground were something to go wrong, or some fool forgets to connect the breaker box end of that wire and it's just left danging in the box."

For the record, we used metal conduit in the military (never for a ground/backup though) for protection and explosion prevention.

Yeah, that's clear, and fair enough, for myself, my own opinion and circumstances, I prefer the added ground wire. I just prefer to do a little higher caliber of workmanship than the minimum required, or what just gets by, I always overbuild and overspec.
That is why for example, if a 2x4 stud is the minimum required size, I use 2x6 or even 2x8 if I feel it's right for the project.

Heh, ok.
Yeah, the metal conduit in that application in the military would be for mechanical protection of the wires, same reason it's required in exposed areas like a basement, laundry room etc where romex if used could be damaged.

I still don't see the point.

Matches next to a gasoline can is a silly comparison, so I won't even comment on that one.

Plastic burns...so what?...you're whole house will burn if it's lit up.

And as far as "no grounding ability", you pull a seperate ground anyway right ...so what's the difference.
