Art 515. Bulk storage plants, which i believe i'm referring to for a local propane dealer, who's GRC & various exp. rated equipment needs replacing due to age & rot.

My plan is to cut the affected (six) 3/4" grc's back to outside the classified area & sweep up and back out of a nema 3r troff, EY's in/out

I've 20' from the fill pad, and 25' from the actual fill tube(s)

T515.3 describes what i'm reading as Class2 Div2 leaving off (for outdoor equipment) @ 3' up from grade, 10' horizontally

Is a 3R troffer up 4' on a pedestal at said distance compliant?

I would probably save the money on the EY's feeding into the trough, because you are not passing through a classified area.

If your "said distance" is the 20' from dispenser and more from the fill and tank, then I would say you don't even need to be up 4'. Anything more than 8' away and above 3' is outside of the classified area, but I would stay 10' because of the tank classified distances.

My answers are based on me correctly understanding what you posted.

I don't know sh*t about classified locations, but my buddy Rob does. :laughing:

I did a few years of gas station upgrades , when the laws changed to require interstisal tanks & veeder roots , but it's been a few decades , so i'm a tad rusty....

Not many people have wired even 1/2 of the stations I have.

I remember when I 1st started using PVC in accordance with 514.8 exception 2. A lot of electricians called me a hack.

Now, most everyone does it unless the customer specs otherwise. A funny thing though, I've heard many a pump and tank installer say you have to use a full 10' stick of conduit before you convert to PVC. They want to argue with me when I tell them that's not accurate. They've always seen electricians not bother to cut/thread conduit, just stub out the 10' section then convert to PVC. So of course they think it's code to use the 10' instead of understanding that it's more cost effective to not worry about cutting/threading the conduit.

I will say, later on I started to use steel 90's in the ground because of the number of conductors and distances we pulled. It helped with the pull.

I always did the full stick because i didn't have to cut/thread anything

I'm wondering about those Ey's ....they seal the pipe(s) in and as well as where they reappear out of the classified zones

my troffer would be in the middle of all that, near the fill station

there is>>>>>

propane repair shop>>>>150' to>>>>filling station>>>>100' to motor/large above ground tank

all 3 areas are classified & sealed

If the conduit is turning up in or running through another classified location, then I retract my comment about not installing the EYS on the conduits coming from the building.

I made an assumption ( ) that they were not.
