NEMA's Take on MC Cable
In August of 2002 The National Electric Manufacturers Association (NEMA) posted a bulletin to clarify the use of a plastic anti-short bushing with cable installations. What's interesting is that they stated that it has been historical practice to use them on MC Cable.
In their words, "the inclusion of anti-short bushings with coils or reels of MC cable is based on historical practice relating to the requirements of 320.40 of the NEC, which mandates the use of anti-short bushing or its equivalent protection for Type AC Cable." To see the actual "NEMA Engineering Department Bulletin No. 90, titled Use of Anti-Short Bushings for Terminating Type MC Cable", click here. Go ahead and leave your comments here on whether you feel they should be mandated for use in conjunction with MC Cable.
Do you think NEMA should mandate the use of anti-short bushing on MC Cable since they are already required for terminating AC Cable and since most electricians use them on MC Cable anyway? Leave your opinion as a comment to this post. I'd like to hear from you!
