Tips

  • Common locations for GFCI outlets are kitchens, bathrooms, and garages.

Common Mistakes to Avoid

1. Ignoring Safety Precautions

Reason: Attempting repairs while the power is still on can lead to serious injury or death from electrocution.
Solution: Always turn off the power at the breaker box before attempting any repairs.

2. Assuming the Problem is with Your Wiring

Reason: Many outages are due to problems outside your home, like downed power lines or transformer issues, leading to wasted time troubleshooting internal wiring.
Solution: Check with your neighbors first to see if they are also experiencing an outage before investigating internal wiring.

3. Failing to Reset Circuit Breakers Properly

Reason: Improperly resetting a tripped breaker may cause further damage or not solve the underlying problem.
Solution: Turn the breaker completely off, wait a few seconds, and then firmly switch it back on to the 'on' position.
