This is a good choice for many hard to re-wire cases. Instead of running a ground wire, or connecting a ground connection to the outlet, you will rely on the GFI function to provide the personal protection. It is not the same thing, but for most instances it is better. A GFI breaker or outlet will trip when there is not the same amount of current flowing in both electrical lines. Better than just letting it travel to the ground via the ground wire, it stops all current flow preventing any shocks.
Surge protectors use the ground wire to redirect the surge until it can trip.
Other outlets can be wired with standard grounded outlets if they are wired through the LOAD side of the GFI outlet. We welcome your feedback. All rights reserved.
