UPS Terminal Connections

FOR U.S. INSTALLATIONS, READ THIS IMPORTANT NOTE
• The mm² and AWG wire size for each circuit breaker size shown on the wiring diagrams. The minimum
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.
