Electrical subpanel repair and installation

Electrical Subpanel Repair & Installation

A subpanel may need repair when breakers overheat, circuits lose power, connections deteriorate or the feeder no longer supports the equipment being used. For new installations, the feeder and main service must support the planned demand. We evaluate the existing panel, feeder, grounding, load and circuit layout before recommending repair, replacement or expansion.

Questions customers ask

Direct answers before you call.

Can an electrical subpanel be repaired?

Yes, when the damaged component and panel condition allow a code-compliant repair. If the bus, enclosure, feeder or obsolete equipment is compromised, replacement may be the appropriate option.

Why does a subpanel breaker keep tripping?

Possible causes include an overloaded circuit, equipment fault, conductor damage, loose termination, failing breaker or a feeder and capacity problem. Testing separates the branch-circuit fault from a subpanel or upstream issue.

Do I need a new subpanel or a service upgrade?

A subpanel creates circuit space and distribution, but it does not increase the utility service capacity. A load evaluation determines whether the existing service and feeder can support the planned circuits.

Field experience

Repair or install the subpanel as part of the complete electrical system.

The feeder, upstream breaker, neutral and grounding arrangement, panel condition and connected loads must work together. Adding breaker spaces—or replacing one breaker—does not correct an undersized feeder or damaged panel equipment.
