I used to always use PVC straps to support PVC conduit until I had several situations where the sun would heat up both the straps and the conduit resulting in the straps snapping off and the conduit left hanging. I've changed over to using metal 2-hole straps and haven't had a call-back since. I recently had a generator install where I ran about 30' of 1" PVC using metal straps to support it. The inspector failed me citing that I had to use PVC straps. After offering my opinion he told me that I'm not supposed to secure the straps too tightly and that both the PVC and the straps need to have the ability to expand and contract. Has anyone else run into this or is it just another NJ thing ? He didn't cite a Code section but if anyone knows if I'm in violation for using metal straps would you please cite a Code section ? Thanks.
I was also cited for not properly securing the whip to the generator. This was a Generac unit that came with a pre-manufactured and installed 5' metallic seal-tight whip and connection box. There was a straight seal-tight connector installed into the bottom of the connection box and an angle connector into the generator. The whip draped down about 18" and then up into a properly secured connection box. The whip was secured on the house side with a strap. Inspector wants me to secure the whip to the generator as well.
Also, (just an FYI) coming down the pike here in NJ are engraved RED phenolic generator warning signs. Using the signs indicated in NEC 700.7 or the ones supplied by the manufacturer apparently are not good enough in many towns. Inspectors claim that the POCO's do not want any signage posted on their meter enclosures and I've come across several townships that now want engraved phenolic generator warning signs firmly secured adjacent to the meter enclosures.
