Thomas & Betts 1228 – Frequently Asked Questions

1) What size conduit does the Thomas & Betts 1228 insulated bushing fit?
The 1228 is a 2-1/2 inch insulated bushing, so it threads onto 2-1/2 inch trade size conduit or a 2-1/2 inch threaded hub. It will not work on 2 inch or 3 inch runs, which take their own size of bushing.
2) Can I use the 1228 bushing as a grounding bushing?
No. The 1228 is a plain insulated bushing for conductor protection at the conduit end. If your installation calls for bonding at the raceway termination, you need an insulated grounding bushing with a lay-in lug or a bonding screw, which is a different fitting in the same 2-1/2 inch size.
3) Why use an insulated bushing instead of a plain metal bushing on a 2-1/2 inch conduit end?
An insulated bushing puts a non-conductive throat between the conductors and the cut edge of the conduit or the metal threads. On a 2-1/2 inch run the conductors are large and heavy, and pulling them over bare metal is where insulation gets nicked. The Thomas & Betts 1228 combines a malleable iron body with that integrated insulation, so you get the mechanical strength of metal plus edge protection for the wire.
4) Is a malleable iron bushing suitable for outdoor or industrial electrical installations?
Malleable iron is the body material on the 1228, and Thomas & Betts lists it for indoor and outdoor use, including commercial and industrial conduit installations as well as maintenance and retrofit work. For a wet location, the bushing itself is an edge protector, not a seal, so the raceway and enclosure fittings still have to provide the rating for the location.
5) What part number do I order for a 2-1/2 inch Thomas & Betts insulated iron bushing?
Order Thomas & Betts model 1228. That is the single orderable model for the 2-1/2 inch insulated malleable iron bushing, so there is no finish or variation to specify with it.
