100 amp main breaker tripped. Checked all the connections. POCO checked their overhead. And this is an interesting service. Main panel in the barn across the road and overhead three wire to house. Looks like the breaker connection got loose and arched on the bus bar. I moved some breakers and added a new Siemens main. POCO was even nice enough to check overhead splices for sub feed to the house. They reset the main and it worked but called us anyways. Looks like I should schedule a panel replacement. Good thing they called.
