Thomas & Betts 601-TB – Frequently Asked Questions

1) Which direction does the Thomas & Betts 601-TB reducer go, 3/4 inch down to 1/2 inch or the other way?
The 601-TB reduces 3/4 inch down to 1/2 inch. The larger 3/4 inch end threads onto the existing conduit or enclosure hub, and the 1/2 inch end takes the smaller conduit. Both ends are threaded, so it is for rigid or IMC threaded conduit runs, not set-screw or compression EMT.
2) Can I use a 601-TB threaded reducer on EMT conduit?
Not directly. The 601-TB is a threaded fitting, so it mates with threaded conduit such as rigid or IMC, or a threaded hub on a box or panel. EMT is not threaded, so you would need an EMT connector or coupling to get to a threaded end first, then land the reducer on that.
3) Can I use a reducer to land 1/2 inch conduit on a 3/4 inch panel knockout or hub?
Yes, that is a standard use for the 601-TB. Thread the 3/4 inch end into the threaded hub on the panel or enclosure, then run your 1/2 inch conduit off the reduced end. For an unthreaded 3/4 inch knockout you will need a threaded hub or connector in the knockout first, since this fitting relies on a threaded connection at both ends.
4) Is the Thomas & Betts 601-TB reducer steel or aluminum?
Steel. That matters if you are mixing it into an aluminum rigid run, where dissimilar metals in a damp or corrosive location can set up galvanic corrosion. For a standard indoor commercial or industrial steel rigid/IMC system it is the matching material.
5) What is the part number for the Thomas & Betts 3/4 to 1/2 inch threaded conduit reducer?
Order it as Thomas & Betts 601-TB. That single model covers the 3/4 inch to 1/2 inch steel threaded reduction, so there is no size or finish choice to specify.
6) Do I need a locknut or bushing with the 601-TB reducer?
The reducer itself is just the threaded size transition between the 3/4 inch and 1/2 inch connections, so anything your enclosure or wire pull needs is a separate line item: locknuts and sealing fittings where the box requires them, and an insulating bushing on the conduit end where the installation calls for protecting conductors at the opening.
7) How do I install a threaded conduit reducer without stripping the threads?
Kill power to the circuit first, confirm your two conduit sizes actually are 3/4 inch and 1/2 inch, then start the 3/4 inch end onto the existing run by hand. Hand-tighten both connections before you put a wrench on them, and finish just snug enough to seat the fitting fully. Check both joints are tight before re-energizing.
