Can someone explain to me the difference between the top Combination AFCI breaker and the bottom 3 CAFCI breakers?
I see the top breaker is 20 Amps and has a white sticker in the bottom corner with an “N” on it pointing where the neutral wire connects to it.
The bottom 3 breakers are only 15 Amps and are labeled with a silver “GND” sticker and have a green sticker with black line in the bottom corner. In this panel, neutral wires were all connected next to these stickers as well.
Are there any defects here? This was in a distribution panel in a condo with a remote disconnect/service panel remotely located, so the ground wires were correctly separated from the neutrals.
Thanks in advance for your help.
