The disconnect was mounted to the unit. They made a 3/4 hole in unit, knocked the ko out of the back of disconnect and did not use a chase nipple. Had a 60 amp breaker and 3ft of #10 ran from breaker to unit. Where they had it mounted the ducts covered the disconnect up.
I would of at least took the time to wire tie the romex to the vent pipe.....
I wired a replacement 10kw heat today that had #10 ran to the unit from a 60a breaker mounted to it today.
