Square D NF12RDE – Frequently Asked Questions
1) Which Square D panelboards does the NF1 extension kit work with?
The NF1 Series extension kit is built for Square D NQ and NF panelboards. Those panelboards use modular construction that accepts field-installable accessories and conversion kits, which is what lets this rail extension go in without swapping out the enclosure.
2) What is the difference between the NF12RDE and NF18RDE extension kits?
Rail extension length is the only choice to make. NF12RDE gives you a 12 inch rail extension, NF18RDE gives you 18 inches. Pick based on how much additional rail length you need for the breaker capacity you are adding.
3) Can I add breaker capacity to an existing NQ panelboard without replacing the enclosure?
That is exactly what this kit does. The NF1 extension kit extends the panelboard's modular rail system to add breaker and load center capacity in the field, so contractors and OEMs can modify an NQ or NF panelboard in place rather than pulling and replacing the can.
4) Is the Square D NF1 extension kit a field-install part or does it need factory assembly?
It is a field-installable, ready-to-assemble kit, intended for on-site design changes to an NQ or NF panelboard. Square D also offers factory-assembled options on the panelboard side if you would rather have the work done up front.
5) Will an ABB panelboard accessory work in place of the Square D NF1 extension kit?
No. ABB panelboard accessories such as the A Series circuit numbering strip for PNBD panelboards or the NKA8474 200% neutral kit for Pro-Stock lighting panelboards are built around ABB's own panelboard lines and serve different functions entirely. The NF1 rail extension is specific to Square D NQ and NF panelboard rail systems.
6) Can I use the Square D NF1 extension kit on an ABB panelboard?
No. The NF1 Series extension kit is engineered for Square D NQ and NF panelboards and relies on their modular rail construction, splice geometry and bracket mounting points. ABB panelboard accessories such as the A Series circuit numbering strip for PNBD panelboards and the NKA8474 neutral kit for Pro-Stock merchandise lighting panelboards are matched to ABB enclosures. Extension hardware has to match the panelboard line it was designed around, so confirm the panel is an NQ or NF before ordering the NF12RDE or NF18RDE.
7) Will an ABB NKA8474 neutral kit work in place of a Square D NF12RDE rail extension?
No - they do different jobs. The NF12RDE is a 12 inch rail extension from the Square D NF1 panelboard extension kit, which ships with a cover plate, rail extensions, support brackets, a screw set and rail splices to lengthen the modular rail system in an NQ or NF panelboard so it accepts more breakers. The ABB NKA8474 is a 200 percent neutral kit for Pro-Stock merchandise lighting panelboards, which addresses neutral conductor capacity rather than rail length, and it is built for ABB panelboards. If the goal is added breaker space in an existing Square D NQ or NF enclosure, the rail extension is the part that does it.
8) Does the Square D NF1 panelboard extension kit meet RoHS requirements?
RoHS compliant, and it is declared mercury free and free of toxic heavy metals. Useful if you are specifying for a project with environmental procurement requirements.
9) I need to relabel panelboard circuits after adding breakers - is that included with the Square D NF1 extension kit?
No. The Square D NF1 Series extension kit is hardware only - one cover plate, two rail extensions, two support brackets, one screw set and two rail splices - so it adds physical breaker capacity but carries no circuit identification. Circuit numbering is a separate item; the ABB 569B806G is an A Series circuit numbering strip for PNBD panelboards, though that is an ABB part for ABB panelboards. For a Square D NQ or NF job, order the extension kit for the rail work and source directory or numbering material for the panel separately.
