plastic insulating bushing

[infinity]

Can i get a code section that says that. i just got turned down because no bushing on a ser connector. SER cable the inspector was unsure as well

300.4(G). An SE connector is not a raceway.

3300.4(G) Insulated Fittings. Where raceways contain 4 AWG
or larger insulated circuit conductors, and these conductors
enter a cabinet, a box, an enclosure, or a raceway, the con-
ductors shall be protected by an identified fitting providing
a smoothly rounded insulating surface, unless the conduc-
tors are separated from the fitting or raceway by identified
insulating material that is securely fastened in place.
Exception:
Where threaded hubs or bosses that are an
integral part of a cabinet, box, enclosure, or raceway pro-
vide a smoothly rounded or flared entry for conductors.
Conduit bushings constructed wholly of insulating ma-
terial shall not be used to secure a fitting or raceway. The
insulating fitting or insulating material shall have a tem-
perature rating not less than the insulation temperature rat-
ing of the installed conductors

thanks. what about an SER cable entering a PVC sleeve with male adapter. We always use bushings on threaded fittings but just curious if it would be required due to the jacket being an insulating protective material.

Since you indicated a sleeve IMO the NEC would not require a bushing.

We always do. Some inspectors want them.
