Thomas & Betts 2672 – Frequently Asked Questions
1) What cable diameter ranges do the Thomas & Betts straight cord connectors cover?
Four cable ranges are offered, each tied to a thread size: 0.250 to 0.400 inch and 0.560 to 0.680 inch on 1/2 inch NPT, 0.400 to 0.560 inch on 3/4 inch NPT, and 1.080 to 1.280 inch on 1-1/4 inch NPT. Measure the outside diameter of the cord jacket, not the conductor bundle, and pick the range it falls inside. A cord under the low end of a range will not get proper grip from the segmented chuck, and one over the high end will not seat.
2) Can I use this cord connector in a Class I Division 1 area?
No. The Thomas & Betts straight cord connector is rated for Class I Division 2, Class II Divisions 1 and 2, and Class III Divisions 1 and 2, in locations where general purpose equipment is permitted. Class I Division 1 is outside that scope, and you need an explosionproof cord grip listed for Division 1 there instead.
3) What thread does this cord grip have, and will it thread into a standard conduit hub?
Threading is NPT, so it mates with standard NPT female hubs, enclosure entries, and locknut/hub fittings at the matching size. Sizes run 1/2, 3/4 and 1-1/4 inch NPT depending on which cable range you order. Use thread sealant on the engagement as you would with any NPT entry.
4) What approvals does this Thomas & Betts cord connector carry for a spec submittal?
It carries UL file E13938 and CSA, plus Coast Guard CG293 compliance for marine and shipboard work. NEC references cited for its hazardous location use are 501-4(b), 502-4(a)(b) and 503-3(a)(b).
5) Is a plastic cord connector suitable for a corrosive or washdown industrial area?
The body is engineered plastic, specifically polyamide (PA), which gives corrosion resistance and electrical insulation that a metal grip does not. That makes it a reasonable pick for chemical plants, food processing, and marine work. Where you need the mechanical toughness or grounding continuity of metal, a die cast or malleable iron cord grip is the better choice.
6) What temperature range can this cord connector handle?
Rated from -34 to +105 degrees C, so it holds up in unheated outdoor and cold storage installations as well as hot process areas near motors and heaters. Match it against the temperature rating of the cord jacket you are pulling through, since the cable is usually the limiting part.
7) Will this cord grip damage the cord jacket on a flexible cable?
The design uses a segmented chuck that clamps around the jacket rather than pinching it, giving high mechanical pullout without cutting into the cord. That matters on portable and vibrating equipment where a poorly gripped cord backs out of the fitting over time.
8) What color are these cord connectors, for matching existing fittings in a panel?
All of them are black polyamide, so they look consistent across a panel or a run of enclosures no matter which cable range you specify.
