mc anti shorts

[strippers&dykes]

Is it required by code to use anti shorts on mc wire?

Not specifically as there is in Section 320.40 for Type AC cable. As with any product, always follow the manufacturer's installation instructions.

It is not required in MC cable. It is in AC cable, 320.40.


Sorry Bryan, we posted at the same time!

all the way at the bottom of the 3rd page it says "antishort bushings are not required"

all the previous being said I use them religously all the time. It only takes one callback and a long troubleshoot to see how easy it would have been to install one of these little helpers.

I agree with you 100%. i install them my self. However it is good information to know for this scenario:

Last two boxes you need to install and you are out of antishort bushings,
A) Do you stop the job and come back tomorrow or
B) You install the MC cable knowing that anti bushing are not required and the inspection will pass or at least you have the confidence to tell the inspector that the short bushings are not required and the job is done.

It is just good information to know. the manufacturer doesn't say "do not install" it says "it is not required" So it is the installers choice.

that is really good information.

Is that valid when debating with the inspector or they want to see the cut sheet or instructions from the manufacturer.

If you know the inspector wants them, why would you want to debate it with him?

Just put them in. It only adds pennies to the job.
If you fight the inspector he will find something else to make your life miserable and it will cost you more.

The key here is using listed for MC connectors.
That means no romex conn. or similar BX type, they must be rated for MC without a bush.
