Common causes
Overload, short circuit, ground fault, arc fault, a failing appliance or a weak breaker can present in similar ways.
- Note what was running
- Unplug portable loads
- Reset once only
- Stop if heat, odor or arcing is present
Malco field guide
A breaker is doing its job when it trips. The important question is whether the cause is ordinary overload, a connected device or a fault in the circuit.

Overload, short circuit, ground fault, arc fault, a failing appliance or a weak breaker can present in similar ways.
Do not replace a breaker with a larger rating, hold it on or repeatedly reset it. Those actions can defeat the protection the wiring depends on.
A technician can isolate the load, test the circuit, inspect terminations and determine whether the breaker, wiring or connected equipment is responsible.
The useful first step
A licensed on-site estimate gives Malco the information needed to explain the real options, cost drivers and safest next step.
Arrange an assessmentStraight answers
No. Electrical symptoms can share several causes. An on-site assessment is the safest way to confirm the condition and scope.
Call immediately for heat, smoke, burning odor, arcing, water near equipment or repeated breaker trips. Avoid opening energized equipment.
