Thomas & Betts 3309 – Frequently Asked Questions

1) What trade sizes does the Thomas & Betts two-screw connector come in?
Three sizes: 3 inch (part 3309), 3-1/2 inch (part 3310), and 4 inch (part 3311). Order by the trade size of the cable or conduit you are terminating, and use the part number rather than the size alone so you get the right one off the shelf.
2) Can I use this connector for a smaller cable, like 1/2 inch or 3/4 inch?
No. The two-screw connector runs 3 inch, 3-1/2 inch, and 4 inch only. For branch circuit sizes you need a different connector from the same family in the smaller trade sizes; these three are large-diameter feeder and service work.
3) Is the Thomas & Betts 3309 two-screw connector steel or die cast?
Malleable iron, with a metallic finish. That is a tougher body than zinc die cast for large trade sizes, which matters on 3 inch and up where the clamp takes real load from the cable weight during a pull.
4) What is a two-screw connector used for in an electrical install?
It is a box connector for non-metallic sheathed cable and conduit fittings: the cable enters the connector, two clamp screws bear down on a saddle to grip the jacket, and the threaded hub and locknut secure it to the knockout in the enclosure. The two-screw clamp gives more even pressure on a large-diameter cable than a single-screw style.
5) Which Thomas & Betts part number is the 3-1/2 inch two-screw connector?
Part 3310 is the 3-1/2 inch. The 3 inch is 3309 and the 4 inch is 3311, so the numbers run in sequence with the size step, which is worth knowing if you are reading a takeoff list that only gives the number.
6) Will the two-screw connector hold up in a damp mechanical room or unheated garage?
The body is malleable iron rather than a plastic or thin-wall material, which is the usual choice for MRO and facility work where a fitting may get knocked or loaded. Match the enclosure and location rating of the rest of the run, since the connector itself is a standard metallic clamp fitting.
