GFCI breaker trips on outdoor BBQ
I built a big brick BBQ 2 years ago and it has worked flawlessly. The BBQ has a dedicated circuit from the garage panel. There is a switch on top (of the counter) that controls an outlet behind the fridge for the rotisserie, and there is one outlet that has power for the fridge. I was required by code to replace the breaker to a 20 amp GFCI, as well as add a disconnect behind the fridge (kinda usless there but that's what the inspector wanted). After doing the mods the GFCI trips as soon as the disconnect is ON. (nothing is plugged in) When the disconnect is off, the breaker doesn't trip. I disconnected the switch for the rotisserie outlet and it still trips with just the single outlet connected to the circuit. (there are no gfi outlets in the line, just a duplex 20 amp that has the bar cut so it separates the 2 outlet hot wires, (so one can be switched). I have double checked all the wires, looking for obvious shorts, and all looks well. I also tried replacing the outlet with a new one, same problem. Also, is there a way to tell if the breaker is tripping due to load, or fault? When the test button is used there is a yellow indicator. When it trips, there is not. This is quite a simple circuit for it to be causing me so many headaches. I wired the entire garage with lights, outlets, welder, and all, with no problems. I think I might be mistreating the GFCI with a switch or something.
