Thomas & Betts 255 – Frequently Asked Questions

1) Will a Thomas & Betts 255 squeeze connector work with both MC cable and flexible metal conduit?
Yes. The T&B 255 is a 3/4 inch straight squeeze connector for armored cable and flexible metal conduit, so it handles AC/MC cable and FMC runs terminating into a box or enclosure. The squeeze (clamp) design grips the armor mechanically rather than threading onto it.
2) I need a connector for 3/8-inch MC cable, not 3/4 inch. Is this the right part?
No. The T&B 255 is sized for 3/4 inch cable and conduit. For 3/8 inch MC/AC cable, look at the Arlington 380ST SNAP2IT connector. If you specifically need 3/8 inch cable landing in a 3/4 inch knockout, the Arlington 407AST is built for that combination.
3) I need to land 3/8-inch MC cable into a 3/4-inch knockout. Will the Thomas & Betts 255 do that?
No. The 255 is built to terminate 3/4-inch armored cable and flexible metal conduit, so a 3/8-inch MC cable would not clamp properly in it. For that combination use the Arlington 407AST SNAP2IT MC cable connector, which is made for a 3/4-inch knockout with 3/8-inch cable and comes in packs of 100. Keep the 255 for openings where the cable itself is 3/4-inch trade size.
4) What is the difference between the Thomas & Betts 255 squeeze connector and the Arlington SNAP2IT 380ST?
The Thomas & Betts 255 is a straight steel squeeze connector sized for 3/4-inch armored cable and flexible metal conduit, tightened down onto the cable with a squeeze clamp rather than threads. The Arlington 380ST is a SNAP2IT snap-in MC/AC cable connector for 3/8-inch cable and is sold 100 to a pack. So the two cover different cable sizes, and the 380ST uses a snap-in body instead of a squeeze clamp. Match the connector to the cable or flex you are terminating: 3/4-inch takes the 255.
5) The Arlington 407AST says 3/4-inch. Is it a substitute for the Thomas & Betts 255?
It is not an equivalent, even though both mention 3/4-inch. On the 407AST, 3/4-inch refers to the knockout it mounts into while the cable it accepts is 3/8-inch. On the Thomas & Betts 255, 3/4-inch describes the armored cable or flexible metal conduit being terminated. Ordering the 407AST for a 3/4-inch flex run would leave you with a connector that cannot clamp the conduit.
6) Is the Thomas & Betts 255 connector steel or die-cast zinc?
Steel. T&B specifies steel construction on the 255, which matters where the fitting takes physical abuse, in industrial areas, mechanical rooms, or anywhere cable gets pulled on after termination. The finish reads metallic, no paint or coating color.
7) Squeeze connector or snap-in connector for MC cable, which should I use?
A squeeze connector like the T&B 255 uses a clamp and screws, so you tighten it down on the armor after the cable is in. It is slower per fitting but lets you back it off and re-seat the cable. A snap-in type, such as the Arlington SNAP2IT line, pushes into the knockout and locks without a locknut, which is faster on high-count rough-ins. On a 3/4 inch run, the 255 is the straightforward clamp option.
8) What is the manufacturer part number for the Thomas & Betts 3/4-inch straight squeeze connector?
Thomas & Betts catalog number 255. That is the number to specify when standardizing a job or restocking a maintenance shop so you get the straight 3/4 inch steel squeeze body and not an angled or different-size version.
9) Can I use a straight squeeze connector where the cable turns tight against the panel?
The 255 is a straight-body fitting, so the cable enters the enclosure in line with the knockout. Where the armor has to make an immediate turn at a panel or a tight junction box, a 90 degree connector is the better choice, since forcing a bend right at a straight fitting strains the armor and the clamp.
10) If I want a connector that installs without tightening a screw, what are my options besides the Thomas & Betts 255?
The 255 uses a squeeze clamp that you compress onto the cable to make the mechanical and electrical connection. If you prefer a push-in style instead, Arlington's SNAP2IT line is the alternative: the 380ST snap-in MC/AC connector for 3/8-inch cable and the 407AST for 3/8-inch cable into a 3/4-inch knockout. Both are SNAP2IT series parts packed 100 per box. Note that neither accepts 3/4-inch cable, so for 3/4-inch terminations the squeeze-style 255 is the part that fits.
11) Does the T&B 255 connector come with a locknut?
Install it as a squeeze-clamp fitting into the knockout and secure it on the inside of the box. Plan on having 3/4 inch locknuts on the truck, and a bonding bushing if your spec calls for one at panel entries. Order the connectors by count for the job; the 255 is sold as the single catalog item rather than a kit with accessories.
12) For a job with a high piece count, which connector ships in bulk packs?
The Arlington SNAP2IT connectors are catalogued in 100-piece packs: the 380ST for 3/8-inch MC/AC cable and the 407AST for 3/8-inch cable in a 3/4-inch knockout. The Thomas & Betts 255 is identified by model 255 as a 3/4-inch straight steel squeeze connector. If your run is 3/8-inch cable, the Arlington packs cover volume work; if it is 3/4-inch flex or armored cable, the 255 is the correct size regardless of pack format.
