Thomas & Betts 3301-TB – Frequently Asked Questions
1) Will a Thomas & Betts 3301-TB connector work with BX and flexible metal conduit, or only armored cable?
Both. The 3301-TB and 3303-TB are armored cable / flexible metal conduit fittings, so they terminate AC (BX) armored cable and flex the same way. The two-screw clamp bears down on the spiral armor to hold it mechanically and keep continuity through the steel body into the box.
2) Can I standardize on one Thomas & Betts connector for all the armored cable in a building?
Not on one part number. The 3301-TB handles 3/8 inch cable and the 3303-TB handles 3/4 inch, so a maintenance stock usually carries both: 3/8 covers the bulk of branch circuit AC/MC, and 3/4 covers the larger feeders and flex whips. Both are the same steel two-screw design, so the install method and tooling are identical across the two.
3) Why use a 2-screw armored cable connector instead of a single-screw or snap-in type?
The two-screw clamp spreads the grip across the armor from both sides, which is what electricians want on heavier runs and vertical drops where a single point of pressure can let the cable creep. Snap-in connectors go in faster but cannot be re-tensioned; with the screws you can back them off, reseat the anti-short bushing, and retighten during a rework. The Thomas & Betts 3301-TB and 3303-TB are the two-screw style in steel.
4) Is the Thomas & Betts 3303-TB cable connector steel or die-cast zinc?
Steel, with a metallic finish. That matters in two ways on a commercial job: steel takes the clamp screw torque without the body distorting, and it keeps the equipment grounding path through the fitting solid rather than relying on a softer pot-metal casting.
5) Does anything else need to be ordered to terminate armored cable with these connectors?
The connector body and its clamp screws are what you get. Anti-short bushings (red heads) for the cut end of the armor and, on most installs, the locknut sequence at the box are the usual companion items on an AC termination, and those are separate line items from the 3301-TB or 3303-TB connector itself.
