Notes for Tables 1 and 2:
1 Based upon UL rating of termination connector and upon 75
o
C copper conductors at 30
o
C ambient from NEC Table 310-16.
Conductor size may vary based on installation requirements.
2 For a 100% switch mode load, it is recommended that you size the neutral conductor for 1.732 times the phase current.
3 For units with external bypass, see Figures
and
4 For UPS module only (UPS input breaker).
5 100% imbalance, provided output current rating is not exceeded.
