    The panel sticker on my HVAC unit says that the max fuse or breaker should be 30 A. But for some reason they have a 60 amp breaker in the main panel. I'm assuming, that's not correct.

      I’m assuming that’s incorrect but it could be correct if it has electric heat kit depending on the model of the heat kit

    You need to run two separate wires, the one with the disconnect already there is for the air conditioner, compressor and fan you will need to run a separate wire for the heat strips which will not have a disconnect. will go directly from breaker to heaters.

      the manufacturer gives you two options. One large circuit and another option for 2 small circuits. Watch the video and read the label.

      @@ikecostner1 it gives you two options but that's not the how the installer installed that unit, that disconnect has a wire going over in a whip to the air conditioner. You need to run a separate wire from the breaker box to the heaters that wire is too small and the disconnect is not sized like you said for the heaters. That's how about every install I've ever done or seeing works. Here in West Virginia we run our own wires and put our breakers in, we don't have electricians do it. Ten-two wire going to the outside unit up to a 50 amp breaker I know most will say max 40 amp breaker for ten two wire but you can go up to 50, according to the NEC code book. Electric heaters will depend on kws if it's 5K 10K 15 or 20 kW to size the wire and breakers, you may run even two wires if you want two different sets of heaters.

      But some of this may depend on code or regulations in a certain state that's extra from the NEC requirements. So if you're in California are you even allowed to still have air conditioning? 🤣😂🤣

      @@davidframe1613 you do not have to run 2 separate feeds or whips, maybe you were taught that way but that’s not required at all.

      @@davidframe1613 your motor can be wired for a higher over current protection than the standard circuit ampacity, but the heat kit doesn’t get a larger breaker than what the ampacity is, all of this info is in article 440 of the NEC
      Maybe you guys do things differently, and by different I mean wrong, so maybe you should hire electricians
