ratings from Table 3‐13 in accordance with the NEC, ANSI/NFPA 70.
The line‐to‐line unbalanced output capability of the UPS is limited only by the full load
per phase current values for AC output to critical load shown in Table 3‐4 on
page 3-9 or Table 3‐5 on page 3-10. The recommended line‐to‐line load unbalance is
50% or less.
