Schneider HC4SN – Frequently Asked Questions

1) Which Square D solid neutral kit do I need for a 400A, 600A, or 800A I-Line panelboard?
The solid neutral assembly kit for Square D I-Line panelboards is sold by line ampere rating, so pick the one that matches the panelboard bus: HC4SN for 400A, HC6SN for 600A, and HC8SN for 800A. All three carry the same 14 AWG to 350kcmil wire range, so the ampere rating is the only choice you make. Ordering the wrong rating is the usual mistake here, since the kits are not interchangeable across bus ratings.
2) Will a Square D HC8SN solid neutral take 350kcmil neutral conductors?
Yes, 350kcmil is the top of the range. The I-Line solid neutral assembly is rated 14 AWG through 350kcmil, so it lands anything from a 14 AWG branch neutral up to a 350kcmil feeder neutral. If your neutral is larger than 350kcmil, this kit is not the one, and parallel 350s or a different neutral assembly are the way around it.
3) Can I add a solid neutral to an I-Line panelboard that was ordered without one?
That is exactly what the HC-series solid neutral assembly kit is for. It is a separately ordered electrical accessory for Square D I-Line panelboards, not a factory-only item, so a panelboard originally built for a three-wire application can be fitted with a neutral bar in the field. Match the kit to the panelboard's line ampere rating: 400A, 600A, or 800A.
4) Does the Square D solid neutral kit fit non-I-Line panelboards or load centers?
No. The HC4SN, HC6SN, and HC8SN solid neutral assemblies are built for Square D I-Line panelboards and mount to that interior. They will not drop into an NQ or NF branch panelboard or a residential load center, which use their own neutral bar kits. If the enclosure is not I-Line, order the neutral kit specific to that panelboard family.
5) Is a solid neutral the same thing as a ground bar in a panelboard?
No, and mixing them up is a common inspection failure. A solid neutral assembly is an insulated bar that lands the grounded (neutral) conductors and stays isolated from the enclosure except where bonding is permitted at the service. A ground bar bonds equipment grounding conductors directly to the enclosure. In an I-Line panelboard used as a subpanel you need both, kept separate. This kit is the neutral, not the ground bar.
6) Is the Square D I-Line solid neutral kit made in the USA for Buy American jobs?
Country of origin is the United States. For federal, state, and institutional work with domestic-content language on the spec, that matters, and it is worth capturing the part number on the submittal: HC4SN, HC6SN, or HC8SN depending on the panelboard rating.
7) Does the Square D solid neutral assembly meet RoHS and Green Premium requirements for a LEED or sustainability submittal?
It carries Schneider's Green Premium product designation and is RoHS compliant with exemptions under the EU directive, with exemption information on file. It is mercury free, and the environmental profile document reference is ENVPEP1407017EN, which is the number to cite on a sustainability submittal. One thing to disclose accurately: the REACH status reports that the reference contains Substances of Very High Concern above the threshold, so if your project has a red-list screening step, flag it there.
8) Can I use one solid neutral kit to standardize across several I-Line panelboards in a building?
Only where the panelboards share a line ampere rating. Standardizing works at the rating level, not across the whole fleet: a facility running 400A and 800A I-Line boards needs HC4SN for the 400A units and HC8SN for the 800A ones. The wire range is common to all of them, 14 AWG to 350kcmil, so an electrician pulling one off the shelf does not have to re-check conductor size, just the panel rating stamped on the interior.
9) Does the Square D HC-series neutral kit ship with recyclable packaging, and is there a take-back program?
Packaging is made with recycled cardboard. It does include some single-use plastic, so it is not classified as sustainable packaging, and there is no manufacturer take-back program for the item. Disposal needs no special recycling operations at end of life. Useful detail if your facility tracks packaging waste on incoming material.
