    Or are they a special bread made for outdoors with a different mounting application?
    To be legal , the circuit breakers must be stamped that they are HVACR rated . And , hopefully the same brand as the loadcenter .

    What are the 2 green wires that attach to the Romex ?

    Low voltage to the condenser ? That would be illegal in my neck of the woods .

    Is here, too; technically. I've taken to knocking out a small blank on the disconnect or drilling a hole and running the LV on the outside of the HV whip when I catch the rare install.

    HACR labeling of circuit breakers is no longer required and was removed from UL 1995 as a requirement for hvacr equipment installations.

    All circuit breakers that meet the requirements of UL 489 for molded circuit breakers satisfies the original testing that was required for HACR and UL dropped the additional testing requirements.

    Also as stated it is an NEC code violation
    725.136 Separation from Electric Light, Power, Class 1, Non–Power-Limited Fire Alarm Circuit Conductors, and Medium-Power Network-Powered Broadband Communications Cables.

    (A) General. Cables and conductors of Class 2 and Class 3 circuits shall not be placed in any cable, cable tray, compartment, enclosure, manhole, outlet box, device box, raceway, or similar fitting with conductors of electric light, power, Class 1, non–power-limited fire alarm circuits, and medium-power network-powered broadband communications circuits unless permitted by 725.136(B) through (I).


    (B) Separated by Barriers. Class 2 and Class 3 circuits shall be permitted to be installed together with the conductors of electric light, power, Class 1, non–power-limited fire alarm and medium power network-powered broadband communications circuits where they are separated by a barrier.

    Biggest thing with having the LV cable on the outside of the whip , over time , the plastic may deteriorate from the UV in sunlight . May depend on the composition of the plastic ?

    But probably closer to code .

    Having a weep hole in the bottom of a rain-tite enclosure is usually not a bad idea , anyway .

    Be careful out there .

    God bless
