Circuit Breaker Repair Shop

The Quad Plus Testing process for circuit breaker repair has set the standard for the industry. We can repair, refurbish and retrofit circuit breakers. Repairs are a significant cost savings compared to purchasing new. Quad Plus Testing is PEARL certified and follows 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.
