- An Overloaded Circuit. You should be able to spot the culprit in this case by looking for an outlet or maybe an individual appliance that’s being used to heavily.
- A Short Circuit. A short circuit is a type of electrical fault. Faults, in general, occur when an electrical current strays beyond its intended path (circuit) due to a lack of resistance (e.g., from insulation or a circuit breaker).
- A Ground Fault. A ground fault is a specific type of short circuit in which the unintentional pathway of the straying electrical current flows directly to the earth (ground) or touches a grounded part of the system (such as a grounding wire or the electric box).
- An Arc Fault. Arc faults result from problems with wiring and terminal connections–for example, a loose terminal screw. Arc fault circuit interrupters (AFCIs), if your home has them and they’re up-to-date, will trip a circuit if a spark forms along faulty wiring.
