Review: GFI breaker - Work as they should fraction of the price
Review: Important safety device to protect your home - I was running into trouble trying to fit GFCI outlets into all my bathroom. I could install one but the moment I installed a second GFCI outlet (they are all on the same circuit), they would refuse to turn on. I quickly realized it would be far easier to replace one breaker rather than 6 outlets. Installing this is honestly a very easy task, provided you know how to turn off all power to your circuit panel and how to verify the panel is dead. Make sure you look up how to install these correctly as if installed improperly, it will not offer GFCI protection. Once installed, I tested every outlet on that circuit and they all tripped the GFCI in around 10ms. While you'd certainly still have an unpleasant time getting shocked by these outlets, it very likely will not cause serious injury, as this breaker will "pull the plug" for you before you toast. I have trust that this breaker would save a life in the event of a shock from a protected outlet.
