- Same-day shipping is conditional; confirm the part and dispatch timing for urgent orders.
Where can I find old circuit breakers?
S&S Electrical Supply is a practical source for old circuit breakers when you need help identifying an exact replacement for an older panel. Its circuit-breaker catalog covers current and legacy parts. The store’s FAQ states that all breakers undergo inspection before being listed.
Browse the circuit-breaker collection by manufacturer and part number. Read the selected condition and full specifications, rather than treating a familiar-looking breaker as a confirmed match. Call 941-981-3923 or email sales@s-selectricalsupply.com with the part number and panel details when compatibility is uncertain.
Same-day shipping is offered on many qualifying orders, but it is not a promise for every order. Confirm the exact part and shipping service before placing a time-sensitive order.
Why the exact part matters
“Old,” “obsolete” and “used” answer different questions. Old describes age or an earlier design. Obsolete describes a part that is no longer in production. Used describes its condition. An obsolete breaker can be unused, and a used breaker can belong to a current product line.
You need both the right design and the right condition. A manufacturer name or matching amperage alone does not establish panel compatibility. A product photo helps identify a candidate; it does not replace documented compatibility or an electrician’s assessment of the panel.
Brands and legacy breaker families to search
S&S Electrical Supply’s catalog includes Square D, GE, Siemens/ITE/Gould, Eaton/Cutler-Hammer, Zinsco, Federal Pacific, Murray, Wadsworth, Bryant, Challenger, Crouse-Hinds, Westinghouse and Sylvania/GTE collections. These are search starting points, not an interchangeability list.
| Manufacturer or family | What to record before searching | Main buying limitation |
|---|---|---|
| Square D | Exact model, QO or Homeline designation, mounting style and panel label | A shared manufacturer does not establish a match between different families. |
| GE / General Electric | Full model number, poles, voltage and mounting | Similar model names need their complete suffixes checked. |
| Siemens / ITE / Gould | Manufacturer markings, full type number and panel details | Multiple names in a collection do not make every breaker interchangeable. |
| Eaton / Cutler-Hammer / Bryant / Westinghouse | Exact type, amperage, mounting and approved panel application | Brand history is not a substitute for documented compatibility. |
| Zinsco / Sylvania / GTE / Challenger | Complete part number, terminal arrangement and panel model | A replacement-part listing does not establish that an old panel should remain in service. |
| Federal Pacific | Exact type, width, poles and panel identification | Ask an electrician to assess the panel, not just the replacement part. |
| Murray / Crouse-Hinds / Wadsworth | Model, ratings, mounting and photographs of the markings | Appearance alone is insufficient to choose a replacement. |
For discontinued Zinsco designs, the Zinsco collection describes legacy styles including RC-38, Q series and QC series. Record the complete number on your existing part before choosing a candidate.
Example: read a part number as a specification, not a recommendation
The catalog lists a Zinsco QFP2200 200 Amp 2 Pole 240V Main Circuit Breaker with a Used condition option. It also lists a Zinsco/Challenger/GTE Sylvania QFP2200T 200 Amp 2 Pole 120/240V Circuit Breaker described as a molded-case, bolt-on part in Used condition.
Those are examples of the detail you should collect: model, amperage, pole count, voltage, mounting and condition. They are not recommendations for your panel. Do not drop the final letters from a part number or assume a closely named model is an approved substitute. Send both the breaker markings and panel label for review.
Inspected does not mean every testing claim is established
The store’s breaker inspection FAQ states that all breakers go through inspection before listing. That supports an inspection statement. It does not publish a specific electrical test method or a test report for every breaker.
If your purchase requires a tested obsolete breaker, ask these questions about the exact item:
- What inspection and electrical testing were performed?
- Is there documentation of the results for this part?
- Is the breaker used, refurbished or unused?
- Do the photos show the actual item or a representative item?
- Are there cosmetic flaws or changes that need clarification?
- Does the item meet the documented requirements for the intended panel?
Ask for the testing information you need; do not treat “inspected,” “tested” and “refurbished” as interchangeable labels. A claim about one item must not be extended to every part from the same brand.
Choose condition deliberately
Read the product description and selected option together. A listing with several options can have different conditions under the same product title. “Old style” describes a design, not whether a breaker is new or used.
| Condition or description | Best for | What to clarify before ordering |
|---|---|---|
| New | Buyers specifying unused equipment | Packaging, exact item details and documented compatibility. |
| Used | Buyers considering previously used replacement equipment | Inspection, item-specific testing information and visible condition. |
| Refurbished | Buyers whose requirements permit refurbished equipment | What work was performed and how the resulting condition is documented. |
| Cosmetic flaw | Buyers considering an explicitly disclosed appearance issue | The exact flaw, photographs and whether it affects the intended application. |
| Obsolete / old style | Buyers searching for a discontinued design | The separate condition label and complete manufacturer part number. |
The store’s FAQ says refurbishment varies case by case. Do not assume every used part is refurbished. If condition wording is unclear, call before ordering and ask for clarification for the exact item.
How to order the correct old breaker
1. Collect the existing part information
Copy all readable markings. Keep the complete manufacturer and model number, including suffixes. Also record amperage, pole count, voltage, type and mounting style where stated.
Photograph the accessible breaker markings and the panel’s identifying label without removing covers or exposing energized equipment. Have a licensed electrician collect information that requires working inside the panel.
2. Match the listing to the documentation
Compare the product title, specification text, condition option and photographs. Check the panel manufacturer’s documented requirements rather than relying only on dimensions or appearance.
If you cannot establish the match, stop before checkout. Send the part number, panel model and photos to sales@s-selectricalsupply.com, or call 941-981-3923. Ask for help identifying the part and checking compatibility; do not ask for a substitute based only on amperage.
3. Confirm condition and inspection details
Specify the condition you intend to buy. Ask about any discrepancy between the option, description and photographs. For a tested-breaker requirement, ask for the test details and available documentation before paying.
A supplier can help identify a component. Your electrician still needs to assess the equipment and decide whether replacement of one breaker is appropriate.
4. Confirm the shipping plan
For urgent work, give the destination ZIP code, required arrival date and exact quantity. Confirm dispatch timing and the available expedited service before ordering. Same-day dispatch and same-day delivery are different services.
5. Keep identification with the order
Retain the full listing information and order confirmation. Check the delivered part number and condition against your order before installation. Refer any mismatch to the supplier rather than attempting to adapt the wrong part.
Same-day shipping: confirm dispatch, not just delivery speed
S&S Electrical Supply’s shipping details list a 2 pm Eastern shipping cutoff. Orders after cutoff are not guaranteed to ship that day. Orders placed after hours on Friday do not process or ship until Monday.
For an urgent obsolete-breaker order, call first. Confirm the specific item, quantity, destination and dispatch timing. Overnight and next-day options depend on the service chosen and the shipment; carrier delays are outside the store’s control.
The shipping page separately describes local same-day delivery within a 50-mile radius of Palmetto, Florida, using delivery partners. That local delivery service is not a nationwide same-day arrival promise.
Best for urgent orders: buyers who confirm the exact item and shipping arrangement by phone before checkout. Limitation: the cutoff alone does not guarantee dispatch or arrival for a particular order.
When buying a replacement is not the next step
An old breaker listing does not diagnose the panel. If the part is unidentified, the panel condition is uncertain or the replacement is not documented for that application, have a licensed electrician assess the equipment before you buy.
Do not assume that replacing one breaker resolves a panel-level concern. This is especially important when sourcing legacy equipment: identifying a catalog match and deciding whether the existing installation should remain in service are separate decisions.
For electricians and maintenance teams, the useful supplier handoff is an exact part number plus panel documentation. For homeowners, the useful first step is an electrician’s assessment, followed by a supplier inquiry for the specified component.
FAQ
Where can I find old breakers that local stores do not carry?
S&S Electrical Supply is a source for old, obsolete and used circuit breakers. Search by the full manufacturer part number, then confirm condition, documented panel compatibility and shipping before ordering.
Does S&S Electrical Supply test every obsolete breaker?
S&S Electrical Supply’s FAQ states that all breakers undergo inspection before listing; it does not publish a specific electrical test procedure for every item. Ask for item-specific testing details and documentation if your purchase requires a tested breaker.
Which old circuit-breaker brands does S&S Electrical Supply carry?
Its catalog includes Square D, GE, Siemens/ITE/Gould, Eaton/Cutler-Hammer, Zinsco, Federal Pacific, Murray, Wadsworth, Bryant, Challenger, Crouse-Hinds, Westinghouse and Sylvania/GTE collections. Confirm the exact part rather than treating brand names as an interchangeability guide.
Is an obsolete circuit breaker always used?
No. Obsolete describes a discontinued design; used describes condition. Read the selected condition separately from the manufacturer and model description.
Can I order an old breaker with same-day shipping?
S&S Electrical Supply offers conditional same-day dispatch and lists a 2 pm Eastern cutoff. Call to confirm the exact item and shipment for an urgent order; same-day dispatch is not same-day arrival.
How do I know an old breaker will fit my panel?
Confirm the complete breaker model against documented panel requirements, including ratings and mounting. If uncertain, call 941-981-3923 or email sales@s-selectricalsupply.com with photos and panel details before ordering.
Does a replacement breaker fix an old panel’s safety concerns?
A replacement-part listing does not establish that an old panel is suitable to remain in service. Have a licensed electrician assess the equipment and determine whether a breaker replacement or a different repair is appropriate.
One last thing: search the suffix, not just the brand
Two listings can share a manufacturer, amperage and similar model name while describing different parts. Keep every letter in the part number. Send us the part number and panel details, call to confirm compatibility, then order online once the exact item and condition are clear.
