Fuel dispenser

[ammklq143]

I have a fuel dispenser and above ground tank with a pump to wire. There are two conduits going to the dispenser and they come up out of the concrete in rigid steel conduit, however, the owner decided to move the dispenser a few feet so they are no longer coming up into the dispenser. It should be fine to come up out of the concrete with my sealing fitting, then an explosion proof j box and a rigid conduit down from that box and run into the pump, shouldn't it? I don't think there's anything that says the conduits have to come up inside the dispenser? They are behind the pump and protected, so that shouldn't be an issue.

Also, the 2nd conduit for the dispenser is for communication cables. Does that need a sealing fitting? It stubs out of the ground at the shop next to the electrical conduits.

Thank you for your help.

Your first situation sounds okay... expensive.. but okay. As long as you take the appropriate means for explosion proofing per 514.

As for your second comment... I'd refer you to 501.10, and 501.15. The handbook commentary for 501.15 helps if you have it... but the gist is yes you need it for the conduit. You should also be concerned with how the cable terminates if you are required to seal the end of the cable as well.

There is not very many areas that are Class I, Division 1 associtated with Article 514 installations.

If you have no arc producing devices in the junction box, there is no reason to use an explosionproof box, unless the box location is in a Division 1 area.
