NOTE Callout letters A, B, C and D map to Figure 5-6 through Figure 5-9.
NOTE Line-up-and-match battery wiring with a 105°C
rating is factory supplied with the Eaton 93PM Integrated Battery Cabinet (IBC).
NOTE The neutral conductor is sized the same as the phase conductor for balanced and resistive loads. Non-linear loads, up to the maximum of 1.5x the load
current, require a larger neutral conductor and should be sized in accordance with NFPA NEC 70 Article 310.15(B)(5)
