recommended circuit breaker sizes for each model and voltage application are listed on the wiring
diagrams.
• Conductor sizes shall be no smaller that the 75°C wire size based on the ampacities given in Table 310.15
(B) of the Electrical code® (NEC®) ANSI/NFPA 70–2020, and article 220. All circuit conductors, including
the neutral conductor, must be the same size ( ampacity ) wire. Code may require a larger AWG size than
shown in this table because of temperatures, number of conductors in the conduit, or long service runs.
Follow local code requirements.
