What drives the number
  • Specialty units (GFI, CAFI, DF, EPD) carry more than standard singles because they cost more new.
  • QOB bolt-ons, 3-pole units, and QOM mains are steadier sellers than loose 1-pole 15 and 20A.
  • Panel takeouts with clean handles and readable labels price close to tested used.
  • We do not publish prices. Metal, demand, and condition move them. You get a written number for your units.
From the yard

QO and Homeline are both Square D and both 120/240V, and they are not interchangeable. QO is 3/4 inch wide with the Visi-Trip window; Homeline is 1 inch. Sort them before you photograph the pile and the offer comes back faster.

Photos we need

Three photos price most breaker lots.

01

The label

The catalog number, straight on and in focus. On a pile, line them up with labels facing the camera.

02

The business end

Line and load terminals, I-Line jaws or bolt-on tabs, and the trip unit or rating plug if it has one.

03

The lot

The whole shelf, bin, or pallet, with a rough count. New in box: the box labels.

Square D prints the catalog number on the face label. On PowerPact and Micrologic units, add a photo of the trip unit.

How selling works
  1. 01
    Photograph the labels

    One clear shot of each catalog number, or the whole shelf with labels facing the camera. A list with counts works for new in box.

  2. 02
    We read them and reply

    During business hours, by text, call, or email, whichever you picked.

  3. 03
    You get a written offer

    Per breaker or per lot. Subject to inspection on pickup.

  4. 04
    We pick up and pay

    Our freight. Wire or ACH within 3 business days of a passed inspection.

FAQ

Selling Square D QO and QOB: what people ask.

Yes, in lots. A bin of 1-pole 15 and 20A QO is worth a pickup when it rides with other equipment or when there are a few hundred of them. Specialty units like QO GFI and CAFI price individually.
