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 2-4. The recommended line-to- line load unbalance is 50% or less. Source protection for the AC input to bypass should be treated as if supplying a 550 kVA three- phase transformer, to allow for inrush current. Bypass input wiring and bypass input breaker rating should be treated as if supplying a 550 kVA load, regardless of the rating
