I Opened this panel and found these white and black conductors landed to the same 20 Amp single pole breaker and the bare ground on the neutral buss carrying the neutral current, no connector in the panel, cable run downstairs into the garage where I am sure there is a concealed splice in the wall before it exists in 500 Wiremold, through the wall of the garage with the wall paper with no raceway to quad receptacles in an office. Lucky for the new condo owner it is still under warranty,
A backup conductor incase one fails also with 2 12 Ga. conductors that could be a 40 amp. circuit & they could have done alot nicer job of drywall texture in that panel too
