Thomas & Betts 3110-TB – Frequently Asked Questions

1) I need a 3/8 inch MC connector that goes into a 3/4 inch knockout. Is the 3110-TB the right one?
No. The 3110-TB is a 3/8 inch connector and takes the standard 1/2 inch knockout for that trade size. For 3/8 inch cable landing in a 3/4 inch knockout, the Arlington Industries 407AST SNAP2IT is built for exactly that combination: 3/4 inch knockout, 3/8 inch cable.
2) What is a direct alternative to the Thomas & Betts 3110-TB for terminating 3/8 inch MC/AC cable?
The Arlington Industries 380ST is a snap-in MC/AC cable connector for 3/8 inch cable and covers the same termination job as the 3110-TB, which is a 3/8 inch steel strain relief connector for armored cable and flexible metal conduit. The main difference is method: the 380ST is from Arlington's SNAP2IT series and snaps into the knockout, while the 3110-TB is a bite-style connector that is seated and secured onto the cable. The 380ST is sold in a pack of 100, so it suits bulk rough-in work.
3) I have a 3/4 inch knockout in the panel and 3/8 inch MC cable. Will the 3110-TB work, or is there a better fitting?
For a 3/4 inch knockout with 3/8 inch MC cable, the Arlington Industries 407AST is built for exactly that pairing - it is an MC cable connector sized for a 3/4 inch knockout and 3/8 inch cable. The Thomas & Betts 3110-TB is specified by cable size, 3/8 inch armored cable or flexible metal conduit, so match it to the knockout the box actually has rather than assuming it fills a 3/4 inch opening. The 407AST ships in a pack of 100.
4) What part number do I order for a 3/8 inch Thomas & Betts strain relief connector?
Order Thomas & Betts 3110-TB. That is the manufacturer part number for the 3/8 inch straight steel strain relief connector for AC cable and flexible metal conduit.
5) Can I use the 3110-TB connector to land MC cable into a panel or enclosure?
That is one of its main uses. The connector provides strain relief at the cable entry into panels and enclosures, protecting the termination from mechanical stress pulling on the conductors inside.
6) Which 3/8 inch connector installs fastest on a large multi-family rough-in?
The Arlington Industries 380ST is a snap-in design from the SNAP2IT series and is supplied in packs of 100, which fits high-count repetitive rough-in. The Thomas & Betts 3110-TB is a steel bite-style strain relief connector installed by seating the cable in the connector and securing the connection to code. If your crew is standardizing on one fitting for hundreds of boxes, the snap-in approach removes a step at each box; if you want a steel connector carrying strain relief at panel and enclosure entries, the 3110-TB is the one to spec.
7) Are the Arlington 380ST and 407AST interchangeable with each other as substitutes for the 3110-TB?
They are not interchangeable with each other. Both are 3/8 inch cable connectors, but the 407AST is specified for a 3/4 inch knockout while the 380ST is listed simply as a 3/8 inch snap-in MC/AC connector. So the deciding spec is the knockout in the box, not the cable. The Thomas & Betts 3110-TB is identified by its 3/8 inch cable size and steel construction, so confirm the knockout on your enclosure before swapping any of the three.
8) What is the 3110-TB connector made of, and will it hold up in an industrial plant?
Steel body, metallic finish. Steel gives it the mechanical strength for industrial and commercial work, which is why it is specified for panel and enclosure entries where the cable takes stress at the termination.
9) Is the Thomas & Betts 3110-TB sold individually or only in bulk packs?
The 3110-TB is listed as a single connector part number. By contrast, the Arlington SNAP2IT 380ST and 407AST are catalogued in packs of 100, which suits crews buying by the carton for a large MC rough-in.
