Recommended Cable Sizes 480 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: Two on input/output/bypass busbars; Four on DC+/DC- busbars; Six on N/G 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

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

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.

NOTE: For the scalable UPS (GVSUPS50K150GS), always size the cables for a UPS rating of 150 kW.
NOTE: Recommended cable sizes and maximum allowable cable size may vary for the auxiliary products. Not all auxiliary products support aluminum cables. Refer to the installation manual provided with the auxiliary product.
NOTE: The DC cable sizes given here are recommendations – Always follow the specific instructions in the battery solution documentation for DC cable sizes and DC EGC cable sizes and ensure that the DC cable sizes match the battery breaker rating.
NOTE: Neutral conductor is sized to handle 1.73 times phase current in case of high harmonic content from non-linear loads. If non or less harmonic currents are expected, neutral conductor can be sized accordingly but not less than the phase conductor.
NOTE: 20-40 kW: DC cables are sized according to 32 battery blocks. 50-100 kW: DC cables are sized according to 40 battery blocks.

Recommended Upstream Protection 480 V

DANGER
Hazard of electric shock, explosion, or arc flash
  • For parallel systems, instantaneous override (Ii) values must not be set higher than 1250 A. Place the label 885-92556 adjacent to the upstream circuit breaker to inform about the hazard.
  • For UPS rating 20-120 kW: In parallel systems with three or more UPSs, a circuit breaker must be installed on the output of each UPS. The unit output breaker (UOB) instantaneous override (Ii) values must not be set higher than 1250 A.
  • For UPS rating 150 kW: In parallel systems with two or more UPSs, a circuit breaker must be installed on the output of each UPS. The unit output breaker (UOB) instantaneous override (Ii) values must not be set higher than 1250 A.
Failure to follow these instructions will result in death or serious injury.
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: For the scalable UPS (GVSUPS50K150GS), always size the upstream protection for a UPS rating of 150 kW.
NOTE: Overcurrent protection is to be provided by others and marked with its function.
