I have three fuel dispensing tanks,1 gasoline, 1 diesel and 1 kerosene each 550 gallons next to each other, the electrician just wire the pump motors using plastic conduit. I though under NFPA 70 it needed to be explosion proof? but can't find that section, any help would be great.
Thanks, Glenn

It has to be Type 'LA' flexible metallic conduit with UL rated end fittings. The end fittings are cast and not stamped or formed. Otherwise it has to be threaded metallic conduit and fittings.
It's in the EXP code.
Those locations are hazardous locations and "explosion-proof" wiring methods and materials must be employed for all or part of the installation.
You can start by reading Article 514, 511, 500, 501, etc., etc.
