At Wendy's, which AWG conductors are required for running power conductors for rooftop unit RT-2?

To select the appropriate American Wire Gauge (AWG) conductors for running power conductors for a rooftop unit like RT-2, you need to consider several factors, such as the amperage rating of the unit, voltage drop, and application.

In the context of commercial rooftop units, the larger the AWG number, the smaller the wire diameter, meaning that options like 2/0, 3/0, and 4/0 provide increasingly more capacity to handle electrical load. The choice of 4/0 AWG indicates that this unit is designed to handle high current requirements efficiently, minimizing voltage drop over longer distances typically involved in commercial installations like rooftop units.

For larger rooftop units that have significant power needs, using 4/0 AWG conductors ensures that the wiring can support heavy loads while maintaining safety standards. This size is often necessary for high-capacity HVAC systems, making it suitable for RT-2.

Using smaller conductors would not only be inadequate for carrying the necessary current but could also lead to overheating and potential safety hazards. Hence, 4/0 AWG is the appropriate choice in this situation, providing the necessary capacity for reliable performance of the rooftop unit.
