I just did a search for anti short bushings and the thread that was most relevant was closed. I hope I'm not opening any wounds by asking another question about them.
I went through the dance with an insector today about the use of them with MC cable. We used roto splits and connectors with bushings. He said he wanted anti shorts, I said give me a code article and he referred me to this:
http://www.nema.org/redirect/redirectFile.cfm?ID=10418&user=187548&filename=/RV1.pdf
It is a document about the proper termination of AC and MC. On page 23 of the document it shows that the proper termination of an MC cable must include a completely squared off edge (there is an illustration but I didn't know how to post just that). His take on it was that he was not requiring the use of an anti short on MC but was letting you get away with an improperly terminated cable if you did use them. He said that if we stripped the cables to the NEMA standard we would not have to use anti shorts. Given the exacting standard set out by NEMA it would be virtually impossible to strip the cable as they set out and have it take less than 5 minutes per strip.
He was reasonable in that since this was the first time we worked in their jurisdiction he would let it go but wanted to warn me that was what was required by his company. FWIW this was an inspector for a private company that works in many different jurisdictions throughout the state.
Just wondering if anyone else has run into this interpretation.
