Circuit Breaker Repair and Reconditioning Facility

The Quad Plus testing process for circuit breaker repair has set the standard for the industry. In our 17,000-square-foot breaker facility, we can repair, refurbish, and retrofit circuit breakers. Our PEARL-certified industrial breaker technicians have over forty years of experience and follow strict reconditioning and refurbishment processes as defined by ANSI/ IEEE C37.59.

  • We inspect each circuit breaker for worn or missing parts.
  • We perform electrical and mechanical testing and analysis to determine any issues with the circuit breaker.
  • Upon approval for repair, defective parts are removed and replaced with new parts.
  • A final test and inspection are performed before the circuit breaker is returned.

Quad Plus Testing will use only OEM or manufacturer-recommended parts. We offer partial reconditioning that focuses only on problem areas or a complete teardown and rebuild of the breaker to return mature breakers into a “like new” condition.

We repair all brands, including:

  • Westinghouse

  • GE

  • Siemens

  • Allis-Chalmers

  • Square-D

  • ITE

  • Cutler-Hammer / EATON

  • BBC/ABB

  • McGraw Edison
