Recommended Cable Sizes 400/415 V

DANGER
hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 4/0 AWG.
Failure to follow these instructions will result in death or serious injury.
NOTE: Overcurrent protection is to be provided by others.

Cable sizes in this manual are based on Table 310.15 (B)(16) of the National Electrical Code (NEC) with the following assertions:

  • 90 °C (194 °F) conductors (75 °C (167 °F) termination)

  • An ambient temperature of 30 °C (86 °F)

  • Use of copper conductors

If the ambient temperature is greater than 30 °C (86 °F), larger conductors are to be selected in accordance with the correction factors of the NEC.

Equipment grounding conductors (PE in this manual) are sized in accordance with NEC Article 250.122 and Table 250.122.

NOTE: The DC cable sizes given here are recommendations – Always follow the specific instructions in the battery solution documentation for DC+ / DC- and DC PE cable sizes.
NOTE: For 100 and 120 kW, use two separate conduits for each of the input, bypass, and output cable sets. Organize cables as illustrated in each conduit to avoid eddy currents (heating).
NOTE: For 150 kW, use two separate conduits for each of the input, bypass, output, and DC cable sets. Organize cables as illustrated in each conduit to avoid eddy currents (heating).
