What we buy
Ranges we buy on this page
We buy used, surplus, failed and obsolete Square D transformers anywhere in North Carolina. This page covers identification, condition checks and removal planning for plant engineers, facility directors, demolition crews and other owners handling compact dry-types or small distribution units.
From a Charlotte mechanical room to a retired Greensboro production line, the useful starting points are the Square D nameplate, enclosure condition and a clear route out.

| 3-phase | 15 kVA - 20 MVA | up to 230 kV | Liquid or dry |

Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
What makes a Square D different
Square D is the Schneider Electric brand that supplied dry-types and small distribution transformers across North American industry. Its compact dry-type enclosures fit into electrical rooms where panelboards, conduit racks and concrete housekeeping pads leave little clearance for inspection or lifting equipment.
The familiar Square D nameplate layout can remain easy to read after 40 years, provided paint, corrosion or grime has not covered it. Photograph the complete plate before disconnecting conductors; that record helps distinguish units whose gray enclosures look nearly identical.
Local reality
Square D vintages and models in the state
An older Square D dry-type in a Winston-Salem plant may have served several generations of machinery without moving from its pad.
Separate the original transformer identification from later electrician labels, especially where a handwritten circuit designation now describes equipment that has already been removed.
Record the actual primary and secondary ratings rather than assuming every Square D enclosure contains a 480-to-208Y/120-volt unit. Model and catalog numbers belong in the identification record, along with kVA, phase and frequency.
Matching enclosure dimensions alone does not establish matching electrical construction.
Around the site
Where they fail
Winding insulation breakdown is a concern for Square D dry-types left in hot mechanical rooms. Restricted ventilation, lint-covered openings and nearby process heat can compound thermal stress.
Burned varnish, darkened winding surfaces or a reported electrical fault warrant documentation, not an attempt to reenergize the unit.
On forced-air Square D units, fan failure can remove the cooling needed for operation at the applicable rating. Record stalled motors, damaged blades and disconnected fan wiring.
A failed fan does not, by itself, establish whether the core and winding assembly escaped heat damage.
Where it sits
The nameplate and the paperwork
For a Square D removal in Raleigh, collect a readable nameplate photograph, overall enclosure photographs and the facility's equipment designation. Include kVA, voltages, serial number and temperature rise class. These details prevent confusion when several similar dry-types share the same electrical room.
An obsolete Square D may still appear on an active one-line diagram after its downstream panel has been abandoned. Have qualified facility personnel reconcile the diagram with field identification.
Maintenance reports, fault records and written release authorization help establish condition and permission to remove it.
On the ground
Inspection priorities
Three checks matter early on a Square D dry-type: temperature rise class, enclosure type and whether the unit has been wet. Read the marked ratings directly.
Do not infer outdoor suitability from a rain-stained cover or assume a basement installation has remained dry.
With the unit safely isolated by qualified personnel, inspect accessible Square D enclosure surfaces for water lines, rust and damaged ventilation openings. Ask about roof leaks, sprinkler discharge and flooding. Moisture history matters even when the exterior has dried and the nameplate remains legible.
Local reality
Getting a Square D out of the building
A compact Square D enclosure can conceal a heavy core and winding assembly. Confirm weight from manufacturer documentation or another reliable record before selecting lifting equipment. In a Durham hospital basement, measure door openings, elevator limits and the turn between the pad and corridor.
Removal planning should identify the Square D unit's approved lifting provisions, anchorage and conductor entry points. Do not treat ventilation slots or sheet-metal covers as lifting points.
Photograph overhead conduit and nearby piping so the crew can plan clearance without improvising beneath a suspended load.
Around the site
How the brand affects our assessment
The Square D name helps organize identification, but it does not establish the condition of a particular unit. A legible plate, documented voltage ratings and an intact enclosure support a clearer assessment than a brand badge on equipment with an unknown fault history.
For Square D units retired from North Carolina facilities, we consider the actual construction, winding condition, moisture exposure and removal requirements.
Separate photographs of each nameplate and enclosure are useful when a demolition project includes several generations of dry-types with different ratings and access constraints.

Questions
Straight answers
Equipment types
Do you buy failed Square D dry-type transformers?
Yes. We buy failed Square D dry-types in North Carolina, including units with winding insulation breakdown or failed cooling fans. Provide the nameplate, photographs and the known failure history. Keep faulted equipment isolated; an energized demonstration is not needed.
Service area
What if my Square D nameplate is unreadable?
Send photographs of the Square D enclosure, remaining labels and any matching maintenance records. A facility one-line diagram may help, but it must correspond to the actual unit. Do not assign voltage or kVA from a neighboring transformer that merely looks similar.
Payment
Can a wet Square D transformer be assessed?
Yes. Identify whether the Square D unit encountered a roof leak, sprinkler discharge or flooding, and provide photographs of water lines or corrosion. Do not energize it to check operation. Moisture exposure must be disclosed even if the enclosure now appears dry.
