Square D NQFTL2H – Frequently Asked Questions
1) What size conductors can I land on the Square D NQ feed-thru lugs?
The lugs terminate AWG 1/0 through 750 kcmil. That covers everything from a small feeder tap up to a full 400A run. Tighten to 6.8 to 7.3 N.m across that whole conductor range.
2) Which NQ feed-thru lug kit do I order, the 225A or the 400A?
Match the kit to the ampere rating of the panelboard you are feeding through. NQFTL2H is the 225A kit and NQFTL4H is the 400A kit. Those are the only two ratings in the family, so a 225A NQ interior takes the 2H and a 400A interior takes the 4H.
3) Can I add feed-thru lugs to an NQ panelboard already installed in the field, or does it have to come from the factory that way?
Field installable. NQ and NF panelboards accept field installable accessories and conversion kits, and this is one of them, which is why it gets used for panelboard modernization and retrofit of existing NQ/NF gear. Factory assembled versions exist too if you are specifying a new panel.
4) Can an ABB 200% neutral kit be used in place of a Square D NQ feed-thru lug kit?
No. The Square D NQFTL kit is a feed-thru lug kit that adds a set of load-side lugs so conductors can be carried through an NQ or NF panelboard, terminating AWG 1/0 through 750 kcmil at 6.8-7.3 N.m and cULus listed. The ABB NKA8474 is a 200 percent neutral kit for Pro-Stock merchandise lighting panelboards, which increases neutral bar capacity rather than providing a feed-thru termination, and it is built for ABB panelboards. The two solve different problems and are not interchangeable, and neither crosses between the ABB and Square D enclosures.
5) Is the Square D NQ feed-thru lug kit listed for commercial work that has to pass inspection?
It carries a cULus listing, which covers both US and Canadian installations. It is also RoHS compliant, mercury free, and free of toxic heavy metals. For an inspector on a commercial or industrial distribution job, the cULus listing is the line that matters.
6) What does a feed-thru lug kit actually do in a panelboard, and when do I need one?
Feed-thru lugs let the incoming feeder pass through one panelboard and continue on to a second one downstream, instead of dead-ending at the first panel. You land the incoming conductors on the main, and the feed-thru lugs on the opposite end carry the same feeder out to the next enclosure. Typical use is daisy-chaining distribution on a floor or a tenant space without running a separate home run back to the switchgear. If nothing is fed downstream, you do not need this kit.
7) Does this Square D kit work on NF panelboards or only NQ?
Both. The kit is engineered for NQ and NF panelboards, as long as the interior is rated 54 circuits or higher. NQ is the branch circuit breaker panelboard line and NF is the companion lighting and appliance line, and the same feed-thru lug kit serves each.
8) My panel is a 30-circuit NQ. Is this the right lug kit?
The Square D NQFTL feed-thru lug kit is engineered for NQ and NF panelboards rated 54 circuits or higher, covering 54, 72, and 84 circuit configurations, so a 30-circuit interior falls outside what this kit is built to fit. The kit is offered in a 225A version (NQFTL2H) and a 400A version (NQFTL4H); choose between those by the panelboard ampere rating once the circuit count is in range.
9) If I only need to label the circuits in my panel, do I need the NQ feed-thru lug kit?
No. The Square D NQFTL is a feed-thru lug kit, a power-carrying accessory that terminates AWG 1/0 through 750 kcmil conductors in NQ and NF panelboards. For identifying circuit positions, the corresponding accessory is a numbering strip such as the ABB 569B806G circuit numbering strip for A Series PNBD panelboards, which carries no current and is matched to its own panelboard line. Ordering the lug kit for a labeling task gets you a conductor termination you do not need.
10) Do I need a torque wrench for these panelboard feed-thru lugs?
Yes, and use one. The terminations are specified at 6.8 to 7.3 N.m for the full AWG 1/0 to 750 kcmil range. That is a narrow window, and an untorqued aluminum or copper termination in a feed-thru position is a heat problem waiting to happen on a 400A feeder.
11) Can I use this instead of a neutral kit or a numbering strip on my panelboard?
No, these are different accessories doing different jobs. The NQ feed-thru lug kit is a line-side power termination for carrying a feeder through to a downstream panel. If you need extra neutral capacity for harmonic loads, that is an oversized neutral accessory such as the ABB NKA8474 200 percent neutral kit for lighting panelboards, and if you are just labeling circuits that is a circuit numbering strip like the ABB A Series strip for PNBD panelboards. Those do not substitute for feed-thru lugs and feed-thru lugs do not substitute for them.
12) Where is the Square D NQ feed-thru lug kit made?
Mexico. That is the stated country of origin, which is the answer some government and institutional procurement packages need for sourcing documentation.
