FAQ

Can I replace an outlet myself?

Yes, if you follow safety steps and have basic tools. Always turn off power at the circuit breaker before starting.

How do I know if an outlet is damaged?

Signs include sparking, a burnt smell, or devices not working properly when plugged in.

What's the difference between a standard outlet and a GFCI outlet?

GFCI (Ground Fault Circuit Interrupter) outlets protect against electrical shocks and are required in areas like kitchens and bathrooms.

Why is my outlet box hot to the touch?

A hot outlet box may indicate an overloaded circuit, poor connections, or a faulty outlet. Turn off the power and consult an electrician.

How often should I check my outlets?

Inspect outlets annually for signs of wear or damage, especially in high-use areas.
