How does that require an anti short bushing? Are you refering to 300.4(F)? It seems to me that a plastic bushing on a locknut satisfies that rule.

You are correct on both counts. That is what I was refering to and yes it satifies that rule.

Just to be clear an anti-short bushing and a raceway bushing are not the same thing.

I would disagree. A piece of FMC with #4 conductors in it would require a bushing at the connector. An anti-short bushing inside of the cut end of the raceway wouldn't satisfy the requirement for a bushing.

What would you do if an inspector made you do it?

Would not do what, use an anti-short bushing on FMC?

I'm not arguing that they are different, what I'm saying is, they serve the same purpose. You are not putting that bushing on to protect the conduit.

An anti-short bushing protects the conductors from the sharp edge of a cut on the armored cable. A raceway bushing is used to protect the conductors when they are pulled into and out of the raceway. Yes, they both provide protection for conductors but their usage and requirements are different and not interchangeable. You cannot use an anti-short bushing in place of a conduit bushing.

It is few and far between on ispections that I see a conduit bushing installed prior to the wire being pulled and I have actually let them use an anti-short bushing if the already heated up. Not so much any more as they will never learn if you let them get away with things to often.

John, there are bushings/liners specifically designed to be installed after the fact. They are made for up to 2"

Oh then I wasn't wrong. Those are the ones I was talking about. Now doesn't that act like an anti-short bushing?
cowboyjwc said:
Well kinda but, anti short bushings go between the cable sheath and the conductors under a connector, whereas bushings, insulated throat connectors, and the above liners are attached to or part of a connector so there is some difference in their uses.

Man, I didn't even notice I hit a thousand posts. Do I get my toaster now?:grin:
A UL listed one of course.
