Circuit Breaker Diagnosis & Replacement

A circuit breaker is a protective device. When it trips, will not reset or feels abnormal, Landmark Electric determines whether the breaker is defective or responding to an overload, short circuit, ground fault, damaged load or panel condition.

Services available within circuit breaker diagnosis & replacement

Circuit Breaker Diagnosis & Replacement includes a defined group of related evaluation, repair, installation and coordination services. Landmark selects only the services supported by the property, equipment and approved project objective.

The written option identifies which services apply, what Landmark supplies, known access limits and any customer, utility, manufacturer or other-trade responsibility before work moves forward.

  • Overload.
  • Short-circuit and ground-fault diagnosis.
  • Compatible breaker replacement.
  • Panel condition review.
  • Circuit Breaker Diagnosis & Replacement evaluation and project-fit review.
  • Existing electrical repairs & troubleshooting system and capacity review.
  • Repair, correction or replacement options based on field findings.
  • Code, equipment-listing and manufacturer-instruction review for the approved scope.
  • Permit, inspection, utility or other-trade coordination when the project requires it.

A tripping breaker is not automatically a bad breaker

Replacing a breaker without testing the circuit can hide the real problem and re-energize a fault. The trip may be caused by too much connected load, damaged insulation, a failed appliance, moisture, a loose connection or required AFCI or GFCI protection responding to a fault.

Landmark reviews the trip pattern, connected loads, breaker type and accessible circuit condition before recommending replacement.

What breaker diagnosis can include

Testing is selected for the reported condition and safe access available at the appointment.

  • Confirm breaker identity, rating and listed compatibility with the panel
  • Review the connected load and when the trip occurs
  • Check accessible terminations for looseness, heat or damage
  • Separate an equipment fault from a branch-circuit fault
  • Evaluate relevant panel condition before installing a replacement

Compatible replacement matters

A breaker must be listed or classified for the specific panel and application. Physical fit alone does not establish compatibility. Required poles, amperage, interrupting rating, conductor size and AFCI or GFCI function must be considered.

Landmark replaces the complete breaker when replacement is supported; internal breaker mechanisms are not field-repaired.

Do not use a breaker as a routine switch unless it is identified for that use

Frequent manual operation can wear equipment not intended for regular switching. When a load needs everyday control, Landmark can evaluate an appropriate switching method rather than relying on repeated breaker operation.

Codes and standards that apply

These references explain the framework for this work. The adopted code, Michigan amendments, local authority, utility rules, equipment listings and manufacturer instructions must be considered together for the actual installation.

Technical content last reviewed August 4, 2026. Requirements may change; project-specific determinations are made from the adopted rules and field conditions.

Frequently asked questions

Can I keep resetting a breaker that trips?

No. If it trips again, leave it off and have the cause evaluated.

Can any breaker that fits be installed?

No. The breaker must be suitable and listed or classified for the panel and application.

Can Landmark repair the inside of a circuit breaker?

No. Internal breaker mechanisms are not field-repaired; a defective breaker is replaced with a compatible device.

Why might a new breaker still trip?

The breaker may be responding to an unresolved overload, short circuit, ground fault, damaged load or wiring condition.

What your service visit includes

Your $79 dispatch and evaluation charge covers sending an electrical professional to your property and the initial on-site evaluation. During that evaluation, the electrician examines the relevant accessible system, shows or explains the supported findings and identifies the cause when the available evidence reasonably allows. Clear, flat-rate options are presented before approved work begins, and the charge is waived when you proceed with approved work during the visit. Any special access, extended diagnosis, permit or after-hours considerations are explained before work moves forward.

Local. Licensed. Ready.

Clear electrical options start with a careful evaluation.
