Line-up-and-match battery wiring with a 105°C rating is factory supplied with the Eaton 93PM Integrated Battery Cabinet
(IBC).
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).
The power wiring terminals are pressure terminations, UL and CSA rated. See
cable terminations.
