NSi ASC2T – Frequently Asked Questions
1) Can I use the NSi ASC2T compression splice to join aluminum wire to copper wire?
Yes. The ASC2T is dual-rated AL9CU, so it accepts both copper and aluminum conductors, including aluminum-to-copper transitions. The barrel comes pre-filled with oxide inhibitor, which is what you need when aluminum is involved, and it is electro-tin plated for corrosion resistance at the connection.
2) What wire sizes does the NSi ASC2T splice take?
It is a 2 AWG splice, with an expanded range of 2 AWG down to 6 AWG when crimped with the NSi N12ID dieless compression tool. The barrel inside diameter is 0.31 inch, so anything larger than 2 AWG will not enter the barrel. It is listed for Class B and Class C stranded cable.
3) Which crimp die do I use on this NSi aluminum splice?
The barrel is marked with the die index and carries a pink die color code cap, so match your tool to the pink index. It is UL Listed for use with other compression tools as well, and the expanded 2 to 6 AWG range specifically applies when you use the NSi N12ID dieless tool.
4) Is this NSi splice rated for 600V feeder and panelboard work?
Yes, 600V with a 90C (194F) maximum conductor temperature, which covers THHN/THWN-2 rated circuits at 90C. It is UL Listed and cULus certified to UL 486A-486B under file E155027, so it satisfies the listed-connector requirement for commercial and industrial distribution wiring.
5) Is this a splice or a lug? Can I land it on a breaker?
It is an inline splice, not a terminal. The ASC2T is a straight barrel with no tang, so there is no pad or hole to bolt to a bus or breaker lug. Use it to join two conductor ends in a pull box, handhole, or gutter. For a terminated end you need a compression lug instead.
6) How do I know the conductors are seated correctly in the barrel before I crimp?
There is a center stop inside the barrel, so each conductor bottoms out at the midpoint and both sides get equal insertion depth. The barrel is 2.38 inches long overall, giving roughly half that per conductor. There is no barrel peep hole on this one, so the center stop is your depth reference.
7) Will this NSi splice fit inside a piece of heat shrink or a splice cover?
The barrel measures 2.38 inches long with a 0.53 inch outside diameter, so size your heat shrink or insulating cover to clear 0.53 inch over the crimped barrel plus the conductor insulation on each end. It ships as a bare tin-plated aluminum sleeve, so insulation is a separate item.
8) How many NSi ASC2T splices come in a box?
They are packaged 24 each, which is worth knowing if you are pricing out a feeder job and need a count per phase plus neutral and spares.
