Thomas & Betts 1255 – Frequently Asked Questions

1) What size conduit does the Thomas & Betts 1255 reducer connect?
The T&B 1255 reduces 2-1/2 inch down to 2 inch, with threaded female connections on both ends. You thread 2-1/2 inch rigid or IMC into the large end and 2 inch into the small end, so it joins two threaded runs without a coupling and a separate bushing.
2) Is the 1255 female on both ends, or does one side thread into a box?
Both ends are female. The 1255 is a female reducer, so it accepts male threaded conduit on each side. If you need to land a 2-1/2 inch opening on a box or enclosure, a female reducer is the wrong part for that; you want a reducing bushing or a reducing washer set instead.
3) Will the T&B 1255 work on rigid metal conduit and IMC?
Yes. Both RMC and IMC use the same NPT-style tapered conduit thread in a given trade size, so a threaded female reducer in 2-1/2 to 2 inch mates with either. It will not work with EMT, which is unthreaded and needs set-screw or compression fittings.
4) Is a malleable iron reducer the right pick over a steel reducing bushing?
Malleable iron is what the 1255 is made from, and it is the usual choice where the fitting takes impact or mechanical load in commercial and industrial conduit runs. A reducing bushing threads into a hub or box opening; this reducer joins two lengths of threaded conduit mid-run. Pick by which connection you actually have at the transition.
5) What exact part number do I order for a 2-1/2 to 2 inch iron female reducer from Thomas & Betts?
Order Thomas & Betts part number 1255. That is the catalog number for the malleable iron female reducer in the 2-1/2 inch to 2 inch size, and it is the only configuration on that number, so there is no finish or variation to specify.
6) Can I use this reducer where a conduit run steps down before a panel?
That is one of its intended uses. The 1255 handles conduit size transitions and electrical panel connections, so stepping a 2-1/2 inch feeder run down to 2 inch ahead of equipment is exactly the job. It also gets used on maintenance and retrofit work where an existing run changes size.
