Thomas & Betts 3304M – Frequently Asked Questions
1) What sizes does the Thomas & Betts insulated two-screw cable connector come in?
Two trade sizes: 1 inch (part 3304M) and 2 inch (part 3307M). Pick the one that matches the trade size of the cable or flexible conduit you are terminating, not the outside diameter of the jacket.
2) Is this a clamp-type connector or a set-screw connector for EMT?
It is a two-screw clamp connector, not an EMT set-screw fitting. The cable or flexible conduit seats under a saddle clamp that is drawn down by two screws, which is the standard termination for armored and flexible cable at a box knockout. For rigid EMT runs you want an EMT set-screw or compression connector instead.
3) Can an Appleton PXSS2K connector be used in place of a Thomas & Betts 3304M two-screw connector?
No, they are built for different jobs. The Thomas & Betts 3304M is an insulated two-screw cable connector in a metallic finish, sized 1 inch, with a companion 3307M in 2 inch - a standard clamp-style fitting that secures cable into a box or enclosure. The Appleton PXSS2K series is a flameproof compound barrier cable connector in nickel-plated brass, intended for hazardous-location terminations where a compound barrier is required. If the opening calls for a flameproof barrier gland, the two-screw connector is not the part; if it is an ordinary cable-to-box termination, the 3304M is the simpler fitting.
4) What does "insulated" mean on a two-screw connector, and do I still need a bushing?
The insulated throat is built into the connector, so an insulating liner protects the conductors as they pass out of the fitting. On the Thomas & Betts 3304M and 3307M that means no separate insulating bushing is needed at the connector throat.
5) What is the finish on the Thomas & Betts 3304M connector?
Metallic, a bare plated die-cast body rather than a painted or coated finish. It is a general-purpose indoor fitting, so in wet, corrosive, or hazardous areas look at a fitting built for that duty, such as the Appleton PXSS2K Series flameproof barrier connector in nickel-plated brass.
6) Can I standardize on one part number across a building for 1 inch cable terminations?
Yes. The 3304M covers every 1 inch termination and the 3307M every 2 inch one, same insulated two-screw design in both, so a maintenance stock of two part numbers covers both sizes with identical install technique for your crews.
