What to check safely
Stay outside the wiring and look for the pattern.
- Note which rooms, lights, outlets, appliances, or exterior devices are affected.
- Look for a tripped GFCI in bathrooms, kitchens, garage, laundry, or outdoor areas.
- Check whether a breaker handle appears tripped without repeatedly forcing it back on.
- Stop using the affected area if there is heat, smell, buzzing, sparks, or shock risk.
