Best for: Older homes or appliances without grounding requirements. Consider upgrading for improved safety.
2. Grounded Receptacle
Appearance: Two vertical slots with a rounded hole beneath.
Function: The third prong (ground) reduces the risk of electrical shock and protects devices from power surges.
Best for: All modern appliances and devices that require a grounding feature.
3. Tamper-Resistant Receptacle (TRR)
Appearance: Similar to grounded outlets but includes built-in shutters.
Function: Prevents objects other than plugs from being inserted, enhancing child safety.
Best for: Homes with children or anywhere added safety is a priority.
4. Arc Fault Circuit Interrupter (AFCI) Receptacle
Appearance: Standard outlet with test and reset buttons.
Function: Reduces fire risks by detecting and interrupting arc faults within the circuit.
Best for: Bedrooms, living rooms, and other areas where arc faults may occur.
5. Ground Fault Circuit Interrupter (GFCI) Receptacle
Appearance: Standard outlet with test and reset buttons, usually marked with “GFCI.”
Function: Shuts off power quickly if a ground fault or current leakage is detected, preventing electric shocks.
Best for: Kitchens, bathrooms, garages, and outdoor areas exposed to moisture.
6. Surge Suppression Receptacle
Appearance: Similar to a grounded outlet but with built-in surge protection.
