Extensive troubleshoot for tripped dual function 15 Qo breaker. Arc was found to be happening in the living room cans. We went ahead and Redeviced the outlets and switches in the living room and upstairs bedroom to prevent further issues. Can connections were fixed and all outlets and switches are now operating properly again. Part of the job was paid warrantied since we apparently installed the cans in the living room not long ago by another technician
