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.
That is a combo AFI/ GFI breaker. I know some of the earlier ones had recalls and were problematic I believe CH especially. That rocker switch should simulate an arc fault one way and a ground fault the other. There is clearly some kind of defect here if this is not cutting power.
Even if the AFCI circuit breakers also provide GFCI protection they are not permitted in lieu of standard GFCI circuit breakers or receptacles which are class A and trip at 4-6ma. If the location for the receptacles requires GFCI protection the AFCI device cannot be used to provide it.
To all those who have already said this, you are correct this breaker will not provide ground fault protection. Additionally though if the test switch is not tripping the breaker that is another defect in itself.
