Odd electrical issue

I have a breaker that keeps tripping, the breaker controls power to 2 bedrooms, no GFCI plugs involved. Unplugged everything, breaker still trips. Started trouble shooting electrical outlets, nothing burned or looks strange, removed one outlet and was able to get the breaker to stay on. This is providing power only to the fan/light in one room, no power to any of the outlets, with the one removed. Each outlet is daisy chained, has 2 neutral/white and 2 hot/black. What’s the next step you all would suggest? I have multi-meter, plug tester. Thanks

Welcome to the forums.

Divide and conquer. Pick a point somewhat in the middle of the circuit and open it.

How old is the house....... what kind of wiring ?
If it's older wiring..... especially metal clad like BX..... the wiring can get shorted where it enters the box at the clamp. Insulation can break off. Sometimes the wiring is pushed to the back of the box when inserting the device and it hits the clamp and shorts.

Use a multimeter set to ohms to check from black to ground.

Since you have already divided out part of the circuit and the breaker stays on it means the issue is downstream of the split. Everything upstream is good.

House was built in 2012. When checking Ohms from black to ground, what am I looking for to know whether it’s good or not?

There should be no resistance measure from black to ground.

Not following what your saying Max, breaker stays on with one outlet disconnected and the fan/light will work. All other lights, outlets will not work. Are you saying the issue is in the fan/light?

I had misread what you wrote. The problem is beyond what you have opened.
