quick question… got the new breaker and everything seems fine, except test switch will not work unless I wire pigtail to ground bus instead of neutral bus. ( of course neutral bus has no connection) should I wire pigtail to ground? or is that gonna cause a neutral /ground bonding that is supposed to be a nono in sub panels?
So my expertise isn’t within home sub panels… but in a professional setting I ground my neutrals 90% of the time. In this scenario, I can see a ground being needed, so I say go connect it to ground
