JuiceBox wiring for the 40A and 75A models

Kris -

This  is a suggested installation wiring guide for our JuiceBox EVSE.  The circuit breaker rating should be rated to 125% of the continuous load. The JuiceBox rating is based on the continuous output allowed per the National Electrical Code.  

 

For the JuiceBox 40 plug in (standard)

You will need the following:

  • A 2-pole, 50A breaker
  • A NEMA 14-50 receptacle ( NEMA 14-50R)
  • #6AWG copper wire with 3 conductors and a ground.  If single conductor THHN wire is used, the ground may be #10AWG per NEC 250.122 calculations
    • Note: the neutral wire is not used, but may need to be present in the receptacle to be to code.
  • If for an outdoor installation, please add the following:
    • A NEMA 14-50R outdoor enclosure
    • Shade for the JuiceBox so it is not in direct sun, exceeding the 90°C mark.

You will need the following:

  • If for an outdoor installation, please add the following:
    • A watertight/weatherproof junction box or enclosure
    • Shade for the JuiceBox so it is not in direct sun, exceeding the 90°C mark.
