A tripped circuit breaker can usually be reset once after removing the load that caused the problem, provided the panel is dry and there is no burning odor, arcing, or visible damage. If it trips again, do not keep forcing resets; the circuit needs diagnosis.
Make sure it is safe to approach the panel
Do not handle a panel that is wet, hot, smells burned, buzzes abnormally, or is arcing. In those conditions, stay away and call an electrician; if there is smoke or fire, contact emergency services.
Turn off or unplug loads on the affected circuit
Turn off or unplug appliances and lights that were operating when the breaker tripped. Reducing the load helps determine whether the event was temporary and prevents the circuit from receiving full demand immediately after reset.
Move the handle fully off, then back on
Many breakers stop in a middle position and will not reset by pushing only toward ON. With dry hands and without removing the panel cover, move the affected handle fully to OFF and then to ON once.
If it trips again, leave the circuit off
An immediate or repeated second trip can indicate an ongoing overload, faulty appliance, or wiring problem. Do not install a larger breaker or open the panel to inspect connections; an electrician should identify the cause.
