Bridgeport Fittings 9791 – Frequently Asked Questions

1) What does a Bridgeport Fittings 9791 knockout insulating bushing actually do in a panel?
It lines the knockout opening so conductors pass over a smooth insulated surface instead of a raw metal edge. The bushing is plastic, which gives the electrical isolation that keeps a conductor from faulting to the enclosure at the entry point. Typical use is service panels, industrial control cabinets, motor control centers, switchgear and commercial enclosures.
2) Is the Bridgeport 9791 bushing metal or plastic, and does that matter for the install?
Plastic. That is the point of the part: a plastic bushing insulates at the knockout instead of adding another conductive surface, and it stands up to the environmental conditions inside an enclosure. If your spec calls for a metallic insulated-throat bushing or a grounding bushing with a lug, this is not that part.
3) What model number do I order for the Bridgeport plastic knockout insulating bushing?
Order it as Bridgeport Fittings model 9791. That is the single model offered for this plastic knockout insulating bushing, so there is no finish or material choice to specify with it.
4) Can I use these insulating bushings in residential service panels as well as commercial gear?
Yes. Bridgeport's 9791 plastic insulating bushing is used across residential service panels, commercial electrical enclosures and industrial control cabinets alike, so a property manager standardizing on one bushing for mixed housing and common-area gear can use the same part throughout.
