Installation Prerequisites

Overview

JuiceBox requires one of the following to be installed by a qualified technician:
  • NEMA 14-50 outlet
  • Hardwired electrical connection
  • The JuiceBox may require a disconnecting means if:
    • Not within line of sight of the Electrical Panel
    • Required by local code
  • Hardwire version: Only the pre-installed, hard wire whip shall be used to connect to a junction box or disconnect. It is not long enough, nor is it meant to go directly into the electrical panel.
CAUTION: Do NOT drill any additional holes into the JuiceBox enclosure as it can cause damage to the PCB and/or electronics inside.

    Location

    When selecting a location to install the outlet or hardwire connection, keep in mind that JuiceBox should be positioned:

    • Within range of the local Wi-Fi network
    • Within reach of the vehicle's charge port
    • Away from direct sunlight (for outdoor installation)
    • Protected from rain (for outdoor installation)
    • With sufficient vertical clearance:
      • Mounted indoors: 24 - 48 in (61 - 122 cm) above the floor
      • Mounted outdoors: 18 - 48 in (46 - 122 cm) above the ground
    • Plug-In Version Only: Within reach of the NEMA 14-50 outlet so that the cable does not strain. The cable is 1 foot (30 cm) long.

    NOTE:

    • For the installation wiring, please have your electrician size the conductors for both rated wire temperature and 125% continuous load. Please refer to both the National Electrical Code (NEC) and your local Authority Having Jurisdiction (AHJ) for any additional requirements.1

    1The neutral wire is not used, but may need to be present in the receptacle.

    Installation

    Fully read and understand the directions before installation. Refer to important safety information at the end of this document.

    This section describes installing the JuiceBox onto a wall mount. If installing onto a JuiceStand, refer to the JuiceStand Manual.

    1. Turn off the circuit breaker to the NEMA 14-50 outlet or hardwired electrical connection.
    2. Use the enclosure screws (x4) to secure the enclosure bracket onto the back of the JuiceBox.
             WARNING: Do not continue this installation until the circuit breaker is turned off.
    1. Install the locking bracket:
      • Standard: Use a wall screw (x1) to secure one side of the wall bracket into the stud closest to the installation area. Use a beam level to ensure that the bracket is level horizontally, then use a wall screw (x1) to secure the other side of the bracket into the wall.
        NOTE: Mount to wood, a stud, or use concrete or dry wall anchors.

      • Locking: Mount the locking bracket to the wall with the center tab facing downwards; the side posts protrude out from the wall and point upwards.
    2. Hang the JuiceBox onto the wall bracket.
    3. Optional: Use a wall screw (x1) to secure the bottom of the enclosure bracket to the wall.
    4. Locking Bracket: Slide the locking bar through the holes in the side posts of the bracket. Secure the locking bar with a padlock.
    5. Connect the JuiceBox to the hardwired connection:
      • Plug-In Version: Plug the JuiceBox into the NEMA 14-50 outlet.
        WARNING: Do not use this device with an extension cord.
      • Hardwire Version: Connect the pigtail harness to the wiring terminal:
         
        Red Black Green
        L1 L2 Ground
        NOTE: No neutral (white) line is used.
        CAUTION: Do not use wire nuts. They might melt at high current.
    6. Turn on the circuit breaker that supplies power to the JuiceBox. Wait 10 seconds.
      Verify that the JuiceBox is powered by checking that the "Power" indicator light on the enclosure is solid green.
    7. Optional: Install the charging cable holder.
      NOTE: Mount to wood, a stud, or use concrete or dry wall anchors.

    Load Balancing

    • Load balance to Circuit only.

    • Load balance to panel is NOT recommended.

    • Can only balance stations with the same specifications (Pro40 with Pro40).

    • 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.
