21 year old gfi breaker keeps tripping. The only item on the line is a two prong power adapter for an electrical toothbrush. Question does anyone know if a gfi breaker when overloaded trips like a standard one where you have to move it to the all the way off position before it will turn back on? When I push the gfi test button it clicks all the way off and can be turned back on without setting it to off position first. I"m trying to determine if I"m having a gfi event or overload. I may just replace the outlet with a gfi unit and the breaker with a standard one. It"s cheaper and then I can tell between an overload and gfi event. It"s in a rental I wired all new 21 years ago, the inspector wanted gfi breakers not outlets.
