I am looking at a job to wire a propane filling station. The gas co is telling me I need an E-stop on the 120V line coming into the control, AND an estop on the 3 phase feeding the motor. Does that make sense? His drawings certainly do not show it.
Also, can I run PVC to the pre-mounted box before the seal-off, or transition to PVC only after I leave the class 1 zone?
