Schneider QO312L125GRB – Frequently Asked Questions

1) Does the Schneider QO main lug load center come with a main breaker?
No. These QO panels are main lugs only, catalogued as Fixed Mains (lugs) with lug-type electrical connections. Incoming conductors land directly on the lugs, so overcurrent protection for the panel has to come from an upstream device (a main breaker or fused disconnect ahead of it). If you need the disconnect at the panel itself, order a main breaker QO load center instead.
2) Is this Schneider QO load center single phase or three phase?
Three phase. It's a three-phase main lugs only load center, so it's intended for 3-phase commercial distribution, not a residential single-phase service. Don't spec it for a 120/240V single-phase panel swap.
3) How many circuits do the Schneider QO GRB load centers hold, and what are the part numbers?
Four sizes, by 1-pole QO breaker spaces: 3 spaces (QO403L60NRB), 12 spaces (QO312L125GRB), 30 spaces (QO330L200GRB) and 42 spaces (QO342L225GRB). Tandem breakers are not counted in these panels, so the space count is the true circuit count.
4) What breakers fit a Schneider QO load center?
QO branch breakers. The panel is part of Schneider's QO range and the bus is built for QO plug-on breakers, so Homeline breakers will not seat in it. Since no tandem breakers are permitted, plan on one QO breaker per pole space.
5) Can I use tandem or twin breakers to add circuits in this QO panel?
No. The QO GRB load centers are rated for zero tandem circuit breakers, so every branch circuit needs its own full space. If you're close on space, size up: the 42-space QO342L225GRB is the largest of the group.
6) Is this QO load center suitable for outdoor or damp locations?
The enclosure is welded galvannealed steel with a surface cover, which gives corrosion resistance and a trim that mounts flush to the box face for easy access to the interior. Galvannealed steel is the standard construction for both indoor and outdoor-rated QO enclosures, so confirm the NEMA type on the specific catalog number matches the environment you're mounting in before you set it outside.
7) How deep is the Schneider QO load center enclosure for wall cavity planning?
Product depth is 4.13 inches. That clears a standard 2x4 stud wall with the box face set to finish, but check gutter space against your conductor sizes on the larger 200A and 225A versions.
8) What is the base plate part number for this QO load center?
The base plate reference is QON403L60N. Useful when you're pulling an interior or matching replacement components to an existing installed panel.
9) Do the Schneider QO load centers meet RoHS and environmental reporting requirements for a green building project?
They're EU RoHS compliant, mercury free, and toxic heavy metal free, and Schneider classes them as a Green Premium product with environmental profile document ENVPEP2212003EN for your submittal package. Note the REACH status: the reference contains Substances of Very High Concern above the threshold, which matters if your project requires a declaration. Recycled metal content at the CR level is 0%, and the packaging is not recycled cardboard and does contain single-use plastic.
