Thomas & Betts 302-TB – Frequently Asked Questions

1) How does the 302-TB attach to the box, threaded or snap-in?
It is an external thread design, so the body threads through the knockout and is secured with a locknut on the inside of the enclosure. That differs from a snap-in style such as the Arlington SNAP2IT 380ST, which pushes into the knockout and locks with no locknut. If your hand cannot get inside the box to run a locknut, the snap-in type is the easier install.
2) Does the 302-TB connector include an insulated throat?
No. The 302-TB is a non-insulated fitting. If your spec or inspector calls for an anti-short bushing or an insulated throat on MC terminations, you will need to add a red head bushing or select an insulated-throat connector.
3) What is a snap-in alternative to the Thomas & Betts 302-TB armored cable connector?
The Thomas & Betts 302-TB is a straight steel connector with an external thread body that screws into the enclosure. If you want a snap-in style instead of a threaded one, the Arlington Industries 380ST SNAP2IT is a snap-in MC/AC cable connector for 3/8 inch cable, sold in packs of 100. The 302-TB uses the threaded external-thread construction with a zinc coated steel housing, so it secures with a locknut-style threaded connection rather than snapping into the knockout.
4) Will a steel AC/MC connector hold up in a damp or unheated space?
The body is steel with an electro zinc plated finish for corrosion protection. Zinc plated steel is intended for dry and indoor locations and general commercial interiors; it is not a substitute for a fitting rated for wet or corrosive environments.
5) Does this connector provide a ground path for MC cable?
The fitting is all steel and clamps the metallic armor, so it maintains the metal-to-metal continuity between the cable armor and the enclosure. It is a screw connection for protective metallic hose, used on armored cable and flexible metal conduit.
6) Difference between the Arlington 380ST and 407AST if I am cross-shopping against the 302-TB?
Both Arlington parts are SNAP2IT series cable connectors. The 380ST is listed as a snap-in MC/AC connector at 3/8 inch, while the 407AST is listed for a 3/4 inch knockout with 3/8 inch cable. The Thomas & Betts 302-TB sits apart from both in how it mounts: it is a straight external-thread steel connector with an electro zinc plated finish, accepting cable from 0.670 to 0.920 inch.
7) How many Thomas & Betts 302-TB connectors come in a box?
Packaging runs 50 pieces to the inner carton and 100 to the outer, with the outer weighing 12 lbs per 100 pieces. That is the figure to use when you are estimating a shipment for a rough-in package.
8) For a large MRO buy, which of these connectors ships in bulk quantities?
The Thomas & Betts 302-TB is packed 50 per inner carton and 100 per outer, at 12 lbs per 100 pieces. The Arlington Industries 380ST and 407AST SNAP2IT connectors are each described as packs of 100, so all three support standardizing on hundred-count quantities for a facility or a multi-building rough-in.
