I do contract labor for an electrician/piping contractor. We are doing a gas station and installed power, intercom, sensor conduits at the dispensers and submersible pumps. The conduit at the dispenser sumps and pump sumps is rigid and is 2' below grade. We extended these conduits with pvc into a building, after coming through the wall at top of footer we sloped pvc up to an elevation of about 1' below finished floor elevation. We turned the conduits up in a 10'stick of rigid bent with 90 which has a seal-off and into a nipple which terminates in a trough. The inspector said that the pvc had to be 24" below grade. If we are outside the 20' radius of class 1 is it legal to use the standard minimum cover? Or does the class 1 boundary extend to the end of the conduit?
Thanks in advance,
