FAQ

What is a GFCI outlet?

A GFCI (Ground Fault Circuit Interrupter) outlet protects against electrical shocks by cutting power if a ground fault is detected, commonly used in wet areas like kitchens and bathrooms.

How do I know if I need an AFCI outlet?

AFCI (Arc Fault Circuit Interrupter) outlets are required in bedrooms and living areas to prevent fires caused by electrical arcs. Check local building codes for requirements.

Can I install a smart outlet myself?

Yes, if you're comfortable with basic electrical work. Turn off the power, follow the manufacturer's instructions, and ensure the outlet is compatible with your home's electrical system.

Are tamper-resistant outlets necessary?

Tamper-resistant outlets are recommended for homes with children as they prevent objects from being inserted into the slots, reducing the risk of electrical shock.

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

A standard outlet provides basic power, while a GFCI outlet includes protection against ground faults, making it safer for areas where water is present.
