Where are GFCI receptacles protected if the receptacle is properly wired?

GFCI receptacles provide protection against ground faults, and when they are properly wired, they protect all devices and outlets that are connected to them downstream. This means that any receptacle or device that is plugged into the GFCI outlet or connected to its load terminals will be protected from ground faults.

This downstream protection is crucial because it ensures that if any device connected to the GFCI receptacle experiences a fault, the GFCI will trip and cut off electrical supply to that device, preventing potential electrical shock hazards. Therefore, understanding that downstream protection is the fundamental aspect of how GFCI receptacles function reinforces their importance in ensuring safety in environments where moisture and electricity can pose a risk, such as kitchens and bathrooms.

The concept of upstream protection would imply that other devices connected earlier in the circuit are protected, but GFCIs specifically serve to protect what is downstream from them. Similarly, "sideStream" is not a recognized term in this context, and "none of the above" would not apply as we clearly see that downstream is valid.
