Square D QOL125 – Frequently Asked Questions

1) What does the Square D QOL125 main lug kit actually do in a QO load center?
QOL125 is a main lug conversion kit for Square D QO loadcenters. Instead of feeding the panel through a main breaker, the kit gives you lugs to land the incoming conductors directly on the bus, so the panel runs as a main lug only device fed and protected upstream. It is rated at 125 A, single phase.
2) Can I use the QOL125 lug kit on a feeder larger than 100 amps?
The kit is rated to 125 A, so it covers 100 A and 125 A feeders. Anything above that needs a higher rated lug kit. Single phase only.
3) I need extra neutral terminations, not a main lug conversion. Is this the right part?
No. QOL125 is a main lug kit for landing incoming feeder conductors at 125 A, not a terminal bar for adding branch neutral and ground points. If you have run out of neutral holes in a panel, an add-on neutral bar such as the NSi Industries 2024 24-circuit stacked neutral bar is the type of part you want.
4) Is the QOL125 lug kit meant for residential panels or commercial panelboards?
Square D classes QOL125 as a residential product, and it is part of the QO loadcenter accessory line rather than the I-Line or NQ commercial panelboard families. For a commercial panelboard conversion you need the lug kit built for that specific panelboard series.
5) What part number do I order for a 100-125A QO main lug kit?
Order Square D QOL125. That is the single model on the kit, so there are no finish or size options to specify.
6) If I convert a QO panel to main lugs with the QOL125, do I still need overcurrent protection?
Yes. Running the panel as main lug only means there is no breaker in the panel protecting the bus, so the feeder has to be protected at the upstream device sized to the 125 A rating or less. Buyers standardizing a building on main breaker panels should stay with a main breaker kit instead.
7) Is the Square D QOL125 made in the USA?
Country of origin is the United States. Square D also lists it as a Green Premium product, RoHS compliant for Europe, mercury free and free of toxic heavy metals, with a published environmental profile under document ENVPEP2212003EN.
