NSi 0T – Frequently Asked Questions

1) Can I use an NSi aluminum set-screw lug on copper wire, or only aluminum?
Both. The NSi set-screw lug is dual-rated (AL9CU style use), so copper and aluminum conductors are both acceptable in the same lug body. The lug itself is 6061T-6 aluminum alloy with an electro-tin plated finish to keep contact resistance down on either metal. That is what makes it usable for copper-to-aluminum transitions at a panel or feeder termination.
2) What wire sizes does the NSi dual-rated set-screw lug cover?
Four wire ranges are offered: 1/0-14 AWG (part 0T), part 2-0T, 250-6 AWG (part 250T), and 1000-500 kcmil (part 86350). Pick by the largest conductor you are landing, and confirm the smallest conductor in the range still falls inside it, since these are range-taking lugs and a small wire in an oversized barrel will not torque correctly.
3) Is this lug rated for 90 C conductors like THHN?
Yes, 90 C is the maximum temperature rating on the NSi lug, so it will not limit a 90 C rated conductor at the termination. Ampacity at the connection is still governed by whatever the terminal on the equipment is rated for, which is commonly 75 C on panelboards and breakers.
4) Will this lug pass inspection for a 600V commercial service or feeder?
It is rated 600V (2000V max per UL486B) and is UL 486A/486B Listed with cULus certification, which is the listing inspectors look for on mechanical connectors used for copper and aluminum terminations. Typical use is panelboard and switchgear terminations, service entrance and feeder work.
5) Is this a one-time crimp lug or can I reuse it?
It is a mechanical set-screw connector, not a compression lug, so it is field-terminable with hand tools and reusable. No crimper or die set required, which is why it gets used on retrofit and renovation work where the conductor may be re-landed.
6) How many conductors does one NSi set-screw lug take?
One. It is a single-port lug, so each conductor gets its own lug. If you are landing multiple feeders on one bus pad you will need a lug per conductor or a multi-port connector instead.
7) Are these NSi lugs made in the USA?
Country of origin is the USA, which matters on public and institutional jobs carrying domestic-sourcing requirements on electrical material.
8) Do I need an anti-oxidant compound with this lug on aluminum wire?
The lug body is 6061T-6 aluminum with electro-tin plating, which is what gives the low-resistance contact on both metals. Follow the manufacturer's installation instructions on the package for whether compound is required for your conductor, and torque the set screw to the value marked on the lug.
