Preplexed by Tripping AFCI

It’s because the AFCI device is not monitoring the conductors that are upstream which are feeding it. It’s monitoring the conductors that are connected to the load side of the AFCI device.

Ah ha!! Makes sense now. Thanks!!

Except… the panel mounted AFCI is monitoring only the downstream hot. The neutral is pigtailed directly to the subpanel (or main panel) neutral, so the AFCI device can’t separately monitor the neutral.

(For a device AFCI/GFCI combo, of course it can monitor both the downstream hot & neutral).

Can you show an example of an AFCI circuit breaker that does not have a connection for both the hot and the neutral on the circuit breaker?

Morning, Robert.
Hope this post finds you well.

It is quite easy to install wall fasteners without worrying what systems are in a wall assembly, behind the drywall. Zircon MetalliScanner M40. I have one in my main tool caddy. Often clients propose, I would like to remove a kitchen or other wall? Is it possible, Mr. Young?
I always say, anything is possible if you have the money and time to do it. Remember though, there are likely systems or components to systems inside the wall assembly that will have to be rerouted or abandoned.

Thanks Robert,
I wonder how reliable those devices are at finding electrical cables? There’s a big disclaimer at the end of the video saying that you should not rely solely on this device to find hidden objects.
