Load Balancing

• Load balance to Circuit only.

• Load balance to panel is NOT recommended.

  NOTE: Balancing to the panel or location can be done on a system that would otherwise work safely on its own. This can reduce usage during peak hours, saving cost to both the user and the owner of the stations.

• Can only balance stations with the same specifications.

• Balancing specifications cannot exceed the rated continuous load of the circuit. (50 amp circuit = 40 amp continuous load allowed) (NEC 625.41 & 42) 2017 code.

• Per NEC 625.42 additional outlets per circuit can be added due to the JuiceNet Automated Load Management System.

• Recommend no more than 3 per circuit. The maximum number of stations per circuit is determined by dividing the number of continuous load amps allowed based on circuit size by 8. (e.g. 40 amps / 8 amps = 5 stations maximum). Note this may result in a slower charge per car.
