You don't even need a bushing on an SER cable connector.

I agree, no extra bonding needed, no bushing needed.

I agree with no bonding bushing, but how about a PB, (insulated bushing)?

Not required but you can install one if you like.
Thought it was raceways with 4 or larger?

You're correct but SER is a cable assembly (Service Entrance cable) not a raceway.

Local codes here require a fiber bushing on any connector larger than 1/2". Wire size does not matter

What is a fiber bushing? :?

I would love to see the wording of that.
It would surprise me if the wording includes cable connectors, that makes no sense.

I find them in old jobs, the look kind of like plastic bushings but made of that brown crap they make some NM boxes out of.

Sorry if there was any confusion. I used the term "fiber bushing" loosely.
We must have some type of bushing whether it be plastic, fiber or metal on any connector larger than 1/2" even if the connector is PVC.

I would love to see the amendment requiring that.
Around here, there is a lot of confusion on this issue, and the NEC rule is surprisingly simple for all the confusion. I hear bushings are required under a bunch of different conditions that I don't believe were ever in the NEC.

I would love to see it too. I can only go by what I have learned by getting turned down for something the inspector says is a local requirement. I have tried to acquire some type of documentation listing all the local codes. Sadly either there is none or I have yet to find the right person to ask. I have some documentation from the mid 80's and we do sometimes get amendments sent to use but a lot of the times we find out what they are when we get turned down for something.
One example which is not very good.
An 8' ground rod is suppose to be 8' in the ground. (Don't have my code book handy so I do not know the correct wording)
In Bartlett, Arlington and Collierville which are in Shelby county, but have their own inspection offices, the ground rod must be 8' in the ground and have a clamp listed for direct burial.
In all other areas of Shelby county, the ground rod must be exposed above the ground with the clamp accessible.

Rick, you know this sounds like inspectors inflicting their will on you without the amendments to back them up, right?

I should have said "threaded connector"

So if I was to use 1" NM connector with a locknut I would have to use a bushing?
That makes no sense to me and like George would like to see the amendment wording.

I think that the application is only on // conduit fittings with exposed threaded(connectors --adapters) ends.As far as Tn.ammendments I don't think it applies to NM type or SER. cable
