Recommended Cable Sizes 208 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 300 kcmil.
Failure to follow these instructions will result in death or serious injury.

The maximum number of cable connections per busbar: 2 on input/output/bypass busbars; 4 on DC+/DC- busbars; 6 on N/PE busbars.

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 or aluminum conductors

  • Installation method C

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 and ensure that the DC cable sizes match the battery breaker rating.

CAUTION
hazard of fire
  • Connect only to a circuit with the below specifications.
  • Connect to a circuit provided with a 250 A branch circuit overcurrent protection maximum in accordance with the National Electrical Code, ANSI/NFPA70, and the Canadian Electrical Code, Part I, C22.1.
Failure to follow these instructions can result in injury or equipment damage.
NOTE: Overcurrent protection is to be provided by others and marked with its function.
