NSi NSITM-TR-750J – Frequently Asked Questions

1) What wire sizes do the NSi TERMINATOR tan/red wire connectors handle?
The NSi TERMINATOR tan/red premium connector is rated for copper conductors from 18 to 12 AWG, which covers the usual 14 and 12 AWG branch circuit work plus smaller 18 and 16 AWG fixture leads. It is rated for copper only, so don't use it on aluminum conductors.
2) Are these UL Listed for inspection on a commercial job?
They are UL Listed as a Pressure-Type Wire Connector and cULus, which is what an inspector looks for on splices in boxes and fixtures. They're also REACH and RoHS compliant, which matters on institutional and government specs.
3) Can I use these wire nuts on 277V lighting circuits?
Yes. These connectors carry a 600V rating, so they're fine on 120/277V lighting and fixture whips as well as standard 120/240V branch circuits.
4) Why is this wire nut two colors instead of one?
The tan/red dual color coding means the single connector covers the combination ranges that normally take two different standard connectors, so one bin item does the work of two on most branch circuit splices. Useful if you're trying to cut down the number of SKUs on the truck or in the stockroom.
5) How many connectors come in the NSi TM-TR-750J?
TM-TR-750J is a 750-piece pack of the tan/red premium connectors. That's a jobsite or stockroom quantity rather than a small contractor card.
6) Do I have to pre-twist the wires before putting these on?
No pre-twisting needed. The zinc-plated steel quick-bite spring grips the conductors as you turn it, and the rounded wing shell gives you enough purchase to torque it down by hand. Strip, hold the conductors even, and drive it on.
7) What is the shell made of, and is it flame retardant?
The shell is thermoplastic rated UL 94V-2 flame retardant, which is what gives it the insulation value inside a crowded junction box or a hot fixture canopy.
8) Will these work for panelboard and load center wiring, or just device boxes?
Both. The 600V rating and 18-12 AWG copper range cover panelboard and load center wiring, lighting fixture and junction box splices, and general branch circuit work in new construction or renovation.
