I've been told that an EE wrote the following about a sewer lift station.
The job was installed (to the best of my knowledge from phone calls) with PVC conduit coming out of the lift station with the cords from the pumps and float switches going to the control box about 5' away from the well. Duct seal was used to seal the conduit. I've seen this method of wiring pass inspection before and I've seen it discussed on this site (I'm pretty sure) as the standard method for wiring a sewer lift station. The State EI turned the job down and wants sealoffs installed in the conduit.
Anyone run into this before?
