A write-up about Anti-Short bushings is finally showing up on Wikipedia. Prior to now, they were considered a commercial product and any postings about anti-short bushings were promptly removed by the team over at Wikipedia. Because they are now so widely used given their obvious safety benefits and wide spread use for terminating both MC Cable and AC Cable, I guess the team finally recognizes them as mainstream.

Parts of the National Electrical Code are now posted online. To view the NEC’s installation diagram for Insulating (Anti-Short) Bushings, as shown in the second edition of the Illustrated Guide to the National Electrical Code, click here.
You’ll have to scroll down on the page to view the whole diagram.
Here’s an animation showing the cutting of MC Cable and the insertion of a plastic anti-short bushing. You’ll notice the animation doesn’t use a roto-split. They use a bx cutter instead, which was used after many people stopped using a hacksaw. To view the animation, click here.
Here’s a great magazine that electrical inspectors read. Apparently it reaches authorities with power of product specification, approval and acceptance. Here’s an article they posted on MC Cable and a brief discussion about the use of plastic anti-short bushings with MC Cable.

According to their website, the National Electrical Installation Standards (NEIS) are “the first quality and performance standards for electrical construction”. They are often developed with expert groups in a joint effort. Because they are quality and performance standards, they also often exceed NEC safety requirements. Here is list of standards in development.
You can’t really afford a short. So most electricians say they use plastic anti-short bushings on MC Cable because they see them as backup insurance against a short, even if they happen to be told they aren’t required on MC Cable for one reason or another.
Looking online, you can find many names for the anti-short bushing including “redheads”, “redeyes”, and even “red devils”. You can also find many ways to spell anti-short bushing, including antishort bushing, anti short bushing, and the correct way which is anti-short bushing. The red color of the anti-short bushing helps inspectors easily find the bushing. If you have any other names or uses for them, feel free to post a comment.
