I'm trying to install a GFCI outlet in my kitchen. My understanding is that you can install one GFCI on the circuit and this will protect all of the other outlets. This is assuming that the GFCI outlet is installed at the beginning of the circuit. (Correct me if I'm wrong about this).
In attempting to identify the outlet at the start of the circuit, I went one by one and disconnected each one of them, testing the others as I did that. They all seem to operate independently of each other. Disconnecting one outlet did nothing to the others.
What makes this puzzling to me is they are all connected to the same circuit breaker. So wouldn't this mean they are all on the same circuit? If they are all on the same circuit, why do all of them continue to work no matter which one is disconnected?
