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 for the 93PM 50 kW Three-Wire SIAC-B are pressure terminations. The power
wiring connections for this equipment are UL and CSA rated. See
