Notes for Tables 5 and 6:
1 Bus bar can accept up to 2 cables per terminal.
2 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.
3 For a 100% switch mode load, it is recommended that you size the neutral cable for 1.732 times the phase current.
4 For units with external bypass, see Figures
5 For UPS module only (UPS input breaker).
6 100% imbalance, provided output current rating is not exceeded.
