FAQ

Can I replace an outlet without turning off the power?

No, always turn off the power at the circuit breaker to avoid electrical shock.

How do I know if I need a 15-amp or 20-amp outlet?

Check the circuit breaker for the outlet. A 15-amp outlet is standard for general use, while a 20-amp outlet is for high-power appliances.

What is a GFCI outlet and when should I use one?

A GFCI outlet protects against electrical shock and should be used in areas near water, such as kitchens, bathrooms, and garages.

Can I use a smart outlet with my existing wiring?

Yes, as long as your wiring supports it. Check the smart outlet's requirements and ensure it's compatible with your electrical system.
