input voltage with an inverter ineffi ciency factored in.
Note – Per the NEC, the DC grounding electrode conductor can be a #6
2
AWG (13.3 mm²) conductor if that is the only connection to the grounding
electrode and that grounding electrode is a pipe, rod, or plate electrode.
Note – Copper wire rated with 75°C (167°F) insulation at an ambient
3
temperature of 30°C (86°F), with a multiple cable fi ll factor (0.8) de-
rating (if needed).
Note – The next larger standard size overcurrent device may be used
4
if the de-rated cable ampacity falls between the standard overcurrent
devices found in the NEC.
