Have 1p 20a breaker that keeps tripping. I turn it on and it buzzes for a second or two and shuts to off. I know it possible the breaker could be bad but the panel/breakers are fairly new. Anything else I can troubleshoot/check? Thank you. It does indicate the rooms it serves on the panel schedule.

Disconnect the wire that goes to the breaker and see if that helps.

What's the circuit used for? Lights? Receptacles? Anything plugged in? Sounds like something is just overloading the circuit. That's what they are there for.

A slow trip like that sounds like a high resistance short. This may be an Easter egg hunt to find the cause.

Nothing at all plugged in. No loads on circuits. Switches that feed receptacles and regular unswitched receptacles. We just gutted house(not sure if it was working prior) so I check if any wires nicked but all looks good.

Nail or screw though cable?

You will need to go to a receptacle near the start of the circuit and disconnect the wires. Test each pair of black and white with a continuity tester (everything unplugged from all on the circuit). That will tell you which direction to look for a short ( continuity means a short).

You also need to test black to ground.
