Good morning, I have 2 cutler hammer arc fault breakers some times they trip together sometimes not, even when nothing is in use. From everything we have traced and dug into which seems to be everything on each circuit there is no crossing neutrals and the two circuits are not even in any of the boxes together. Any ideas? Thank you

If they are the old style, I’d replace them with the new kind that has trip codes.

Did one the other day and it showed internal failure. Lot quicker and easier than tearing into a house full of wiring, chasing a ghost.

Many General contractors use laborers that wont read OEM test procedures, or fault codes

Thank you, just replaced both breakers and will see if that solves it.

Many non-residential electricians on this forum wont read instructions, if WAG replacements, or getting answers on the internet is easier.

Not surprisingly, I have no idea what you’re talking about.

I believe the OP is an electrician, not a General Contractor. Nor is there any indication he sent a laborer to trouble shoot it.
