I inspected a home built in 1950 today. In the Kitchen there are 3 prong outlets across the counters. I tested each of them and none them were protected with GFCI outlets. Not all that unusual in some of our older homes. They all showed an open ground, again not all that unusual in some of our older homes.
When I inspected the panel I found a fairly new Cuttler-Hamer panel with relatively new branch wiring, with ground. On the Kitchen circuit I found the breaker pictured here. My first thought was this is just an arc fault breaker, but the test button is more like a rocker switch. when moved in either position it does trip the breaker.
Any assistance on what I am seeing? I am not sure if this is also supposed to be GFCI and it is not wired correctly, or it is not offering the protection.
Thanks in advance,
