Thomas & Betts 2920NM – Frequently Asked Questions
1) What cable diameter range does the Thomas & Betts 2920NM cord connector grip?
The 2920NM accepts cable from 3.2mm to 9.5mm outside diameter, which is 0.125 inch to 0.375 inch. Measure the jacket OD of your cord, not the conductor size. Anything under 1/8 inch will not get proper strain relief, and anything over 3/8 inch will not pass the gland.
2) Can I use a 2920NM cord connector outdoors or in a washdown area?
It is rated for ordinary, wet, or dry locations and carries an IP65 degree of protection, so it handles rain and hose-directed water when properly tightened on the cord. IP65 is dust tight and water-jet resistant, not submersible, so don't use it where the fitting sits underwater.
3) Is the 2920NM cord connector UL listed and CSA certified?
Yes. It carries UL file E13938 and CSA 52391, so it satisfies the listed-fitting requirement for a cord entry into an enclosure on both US and Canadian jobs.
4) What is the difference between the Thomas & Betts 2920NM cord connector and the Bridgeport Fittings RSR-2106?
Two things separate them: thread size and body material. The 2920NM is a straight cord connector with a 1/2 inch NPT thread, molded in polyamide/nylon 6.6. The Bridgeport RSR-2106 is an aluminum cord grip connector with a 3/4 inch NPT thread. So the match depends on the hub you are landing in - a 1/2 inch knockout or hub takes the 2920NM, a 3/4 inch opening takes the RSR-2106 - and on whether you want a nonmetallic or a metal gland at that penetration.
5) Is the Thomas & Betts 2920NM metal or plastic, and will it hold up in a corrosive plant environment?
It is a nonmetallic fitting, molded from polyamide (nylon 6.6) in black. Nylon resists the moisture and many of the chemicals that pit aluminum, which is why it gets specified in food plants and washdown areas. If the spec on your drawing calls for a metallic cord grip, the Bridgeport Fittings RSR-2106 is an aluminum-bodied alternative.
6) What temperature range can the 2920NM nylon cord grip handle?
Service range is -34 to +105 degrees C (roughly -29 to 221 F). That covers unheated outdoor enclosures in cold climates and hot equipment cabinets, but it is below what you'd want hard against a high-temperature luminaire housing or oven skin.
7) Does the 2920NM provide strain relief, or do I still need a separate cord grip?
Strain relief is built in. The gland nut clamps the cord jacket and is shaped to restrict bending right at the entry, so the pull is taken on the jacket instead of the terminations inside the box. No separate grip or Kellems-style support is needed within its 3.2 to 9.5mm cable range.
8) How do 2920NM cord connectors come packaged for a bulk order?
They ship 25 per inner carton and 100 per outer, with the outer running about 5 lbs per 100 pieces. Inner carton measures 6x5x4 inches and the master carton 12.75x8.75x5.5 inches, which matters if you are staging material on a cart or in a job box.
