If removal or inspection requires accessing energized equipment, stop and hire appropriately qualified electrical professionals. Follow the current manufacturer instructions and the authority having jurisdiction. If you see burned insulation, melted plastic, unusual odors, or loose main terminations, document those conditions and do not proceed without professional assessment.

01

What we review and how to begin

We review qualifying Square D MasterPact breakers, their draw-out cradles, and compatible trip units for purchase consideration. Submissions that include original breaker assemblies and the matching cradle or trip-unit evidence allow a faster, more accurate evaluation. Submission does not imply purchase; each item is reviewed against current buyer needs, identification clarity, and observed condition. Manufacturer names are used for identification only.

Before you remove equipment or move it for any reason, gather the identification details and photographs described below. If removal involves live systems or uncertainty about condition, stop and use appropriately qualified electrical professionals and follow the current manufacturer instructions and the authority having jurisdiction. Clear, truthful descriptions and organized photos help determine whether an item is a potential fit for purchase review.

    Exact identification fields we need

    Provide the exact identification fields shown on the breaker and cradle nameplates. Key fields that speed review and reduce follow-up include the catalog or model number, frame size (A-frame designation), ampere rating, trip unit type and code, factory part numbers on the cradle, serial number, and the manufacturer date code when present. If original labels are missing or replaced, note that clearly and add any other traceable evidence, such as engraved tags or panel schedules.

    If the trip unit is removable, include the trip unit part number and any calibration or version labels that are visible. When breakers are installed, list the mounting or panel type and note whether the unit is draw-out, fixed, or conversion-mounted. Do not assume compatibility from physical appearance alone; list only what is shown on manufacturer markings and documents in your possession.

    • Catalog/model number
    • Frame size and ampere rating
    • Trip unit type and part number
    • Cradle/adapter part numbers and serial numbers

    Completeness checklist — what to include

    Complete assemblies are easier to evaluate and more likely to align with current buyer requests. For each breaker or lot, indicate which original accessories are present: the draw-out cradle, racking handle and mechanism, door interlocks, trip unit, control wiring harnesses, secondary disconnects where applicable, and any factory-mounted ancillary devices such as shunt trips or undervoltage releases. If an accessory is missing, damaged, or of unknown status, say so directly and include photos.

    Use this checklist to describe condition with straightforward, observable facts. Avoid general terms like “works” without context. Instead, share what is known: whether the breaker was last known energized and when, visible evidence such as intact labels, corrosion, discoloration, broken latches, missing hardware, or cracked covers. If you have documentation such as packing slips, panel schedules, or commissioning records, reference the document titles and dates without including sensitive information.

    • Breaker assembly: present/missing/damaged
    • Draw-out cradle and racking hardware: present/missing
    • Trip unit: present with part number or absent
    • Ancillary devices (shunt trip, UVR) and control wiring: list status

    Photos that answer questions quickly

    Good photos reduce delays and follow-up. Take clear, well-lit images of the breaker front, both sides if accessible, the main nameplate and serial number, the trip-unit nameplate, and the cradle or draw-out housing showing its part number and any wear points. Show the breaker in the cradle and, only if performed by a qualified professional and where safe and permitted, an image of the cradle racking mechanism (e.g., with the breaker fully inserted or fully withdrawn). Photos that capture context—such as the surrounding panel and any labeling—help confirm the exact configuration.

    Do not energize equipment or remove live covers to obtain pictures. If removal or handling must be performed, have a qualified electrical professional carry it out and stop for warning signs such as burned insulation, melted plastic, unusual odors, or loose main terminations. If such damage exists, document it in the photos and description so the condition can be understood without further disassembly. Clear file naming that ties each image to a specific serial number helps prevent mix-ups.

    • Front nameplate and serial number close-up
    • Trip-unit label close-up
    • Cradle part number and racking mechanism (qualified professionals only)
    • Overall shots showing breaker in cradle and surrounding panel

    How to organize multiple breakers or lots

    When offering multiple breakers, organize by identical part number and similar condition. Create a simple manifest or spreadsheet listing each item’s serial number, model/catalog number, frame size, ampere rating, trip-unit details, condition code (e.g., new-surplus, used serviceable, cosmetic-damage), and the photo file names that correspond to each line. This structure reduces back-and-forth and makes it easier to evaluate potential fit and quantities.

    Label crates or pallets with the lot number that matches the manifest and keep like items together. If items are spread across locations, indicate quantities per site and any access constraints or lead considerations. For large lots, include a summary count by model and an itemized sample set of photos for representative units, plus notes about the range of conditions observed across the lot.

    • One manifest per lot: serial, model, frame, condition
    • Label physical lots to match digital manifest
    • Group identical, same-condition items together

    Scope we typically consider and important restrictions

    We typically consider Square D MasterPact breakers and associated draw-out cradles and trip units that are offered as original assemblies and that match the identification and completeness evidence above. Acceptable condition types may include new-surplus, used-serviceable, obsolete, and surplus stock. Each submission is individually reviewed and may or may not qualify for purchase consideration, depending on identification clarity, observed condition, and current buyer interest.

    Website submissions do not constitute an appraisal, offer, acceptance, safety inspection, compatibility determination, purchase order, or shipping authorization. Items suspected of fire damage, severe water exposure, or tampering should include clear photographic evidence and a description of the event if they are submitted for review. If identification is unclear or missing, explain what is known and provide any available supporting documentation or contextual clues.

    • We consider assemblies with original breaker and cradle evidence
    • Submissions are individually reviewed; not all items will be purchased
    • Do not submit equipment with unclear or missing identification without explanation

    How to submit an inquiry and what to expect next

    Include the manifest or a clear itemized list, the required photos, and a contact point for follow-up. Common fields that speed response include quantity, location, preferred disposition (sell/scrap/reuse), any access or handling constraints, and whether documents of ownership are available. Name photo files by serial or lot number to align with your manifest and reduce confusion during review.

    After you submit, the information is reviewed and additional details may be requested. You may be asked for more photos or clarification of condition and completeness. A website submission is the first step in evaluation only and does not create a purchase commitment. If removal or handling is required, use qualified professionals and follow manufacturer instructions and local authority guidance. Communication about next steps depends on the completeness and clarity of the information provided.

    • Attach manifest and photos (JPEG/PNG) named by serial or lot number
    • Provide location, quantity, and access constraints
    • State preferred next steps and available documentation of ownership
