Ok shut off the two 20amp breakers and removed those two black wires on top.
Ems reads ok,turned on main 50amp breaker in Moho and flipped all breakers on one at a time and all good. Then turned on the two 20amp ones and still all good.
Went to re connect the two black and triped the 50amp gfi in my basement.
Could still be the charging system, transfer switch, or something on the two branch circuits.
Diagram shows the two feeds as 525 (A/C pass through input) and 528 (power for charging system). With the 20a circuit breakers off reconnect one of the black wires at a time and hopefully identify which one is what.
If that holds then turn on the 20 amp breakers one at a time. I suspect the inverter charging system or the insta-hot. Unless you have something odd plugged in.
Or explain what you have done and let your electrician evaluate the rest.
