My 200 amp (Siemens eq9685) main breaker keeps tripping. I noticed the right side of the breaker is hot to touch. So I figured it was something loose and checked all connections and everthing is tight. Turned everthing back on and hooked up the amp meter. Under a low amp draw everything is fine. Get the amp draw up to around 75-80 the breaker heats up and trips. Is it the breaker going bad or is there something else i need to check?

Thanks

Bad connection to the buss.
This needs to be checked soon, or you will have to replace the panel.

Would this be pulling the breaker and check the buss bar for discolor?

No this is for a licensed electrician. You cannot do this hot. The meter would have to be pulled

I wouldn't do it hot. I have a disconnect under the meter.

Do you have a picture of your panel? Is your main removable, some arent?

Sorry for the pics being sideways. They loaded up that way for some reason.

I cant tell are they set screws or rivets holding it down

They are screws.

Almost looks like it could be turned into a main lug panel by bolting some lugs on those studs. But I would not take it apart till I had some replacement parts on hand ready to replace it.

Have you checked all your connections in both panels to make sure they are tight?
