Square D NFLALLC – Frequently Asked Questions

1) Will the NFLALLC barrier fit my Square D NQ panelboard, or is it NF only?
It works on both. The barrier is made for Square D's NQ and NF panelboard platform, which uses modular construction that accepts field-installable accessories and conversion kits. What it will not cover is a main breaker of a different frame class - this one is specific to LA/LH type main breakers, so a panelboard mained with a different breaker frame needs the barrier made for that frame.
2) Will a Square D NFLALLC barrier work in an Eaton or ABB panel?
No. The NFLALLC barrier is dimensioned for the Square D NQ/NF interior and LA/LH main breaker, so it has no place in another manufacturer's enclosure. Other brands have their own interior accessories - ZenSupply carries the Eaton Pow-R-Stock Series Rating Kit for PRL1X/2X and PRL1A/2A panel systems, and the ABB THQC 1-pole front mounting plate, for example. Panelboard interior parts are not cross-brand items.
3) Is the Eaton Pow-R-Stock series rating kit an alternative to the Square D NFLALLC main breaker barrier?
No. The Square D NFLALLC is a main circuit breaker barrier for UL service entrance configurations on Square D NQ and NF panelboards, supplied two pieces per set. The Eaton SRK is a series rating kit for Eaton PRL1X/2X and PRL1A/2A panel systems, so it serves a different function on a different panel line. If the panel in the field is a Square D NQ or NF and the requirement is the service entrance barrier, the NFLALLC is the part; the Eaton kit will not substitute for it.
4) Can I add the NFLALLC barrier to a panelboard that is already installed, or does it have to come from the factory?
It can go in on the job. Square D supplies the NQ/NF accessory line as ready-to-assemble kits and field-installable components, so the barrier can be added to an existing panelboard during a service entrance conversion or retrofit. Factory-assembled options also exist if you would rather have it built in up front.
5) Is the Square D NFLALLC service entrance barrier UL Listed for inspection?
Yes, the NFLALLC barrier is UL Listed, which is what matters when an inspector is looking at a panelboard being used as service entrance equipment. It is also RoHS compliant and free of mercury and toxic heavy metals.
6) How many barriers do I get when I order one NFLALLC?
One order of NFLALLC is a single set, packaged 1 each, and that set contains 2 pieces. You do not need to order two to get a complete barrier for one main breaker.
7) What is the exact part number for the Square D NF LA/LH main breaker barrier?
Order it as Square D NFLALLC. That is the manufacturer part number for the LA/LH main circuit breaker barrier on the NF/NQ panelboard line, and there is one configuration - no finish or size choice to specify.
8) Where is the Square D NFLALLC barrier made?
The NFLALLC barrier is manufactured in Mexico. That matters on public work with domestic sourcing requirements, so check it against your project's procurement terms before you spec it.
