Installation

Overview

JuiceBox requires either a hardwired electrical connection or a NEMA 14-50 outlet.

The JuiceBox power supply must be connected to a circuit breaker that is rated for at least 125% of the device's continuous load.

• 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 hardwire connection or outlet, keep in mind that JuiceBox should be positioned:

• Within reach of the vehicle's charge port
• 18 inches above the floor or ground
• If applicable, within range of a cellular connection or the local Wi-Fi network

Wiring And Circuit Requirements

For additional specifications, refer to the Specifications section.

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 Pro 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, NEMA 6-50 outlet, or hardwired electrical connection.

2. Use a stud sensor to determine an appropriate mounting location, then use the 2 screws to secure the wall bracket.

3. Insert the enclosure screws into the enclosure, as shown. Tighten the screws until approximately 2 mm of thread are visible.

4. Hang the JuiceBox onto the wall bracket.
   NOTE: If the JuiceBox does not hang securely, adjust the screws that were installed in step 3. The 48 and 80 amp are hardwire only and do not have a plug as shown.

5. Connect the JuiceBox:
   • Plug-In Version: Plug the JuiceBox into the NEMA 14-50 outlet or NEMA 6-50 outlet.
   • 1-Phase Hardwired Version: Connect the harness to the junction box.
     WARNING: It is the installers responsibility to ensure that the JuiceBox is wired in accordance with the local electrical code.
     NOTE: The hardwire versions of the JuiceBox are shipped with appropriate wires that meet the National Electric Code (NEC) NFPA 70 and require a nearby junction box connection. Any alteration of the supplied wiring will invalidate the warranty and may not conform to NEC.

     L2 (Red)	8 AWG	6 AWG	3 AWG
     Ground (Green)	8 AWG (THHN)	8 AWG (THHN)	6 AWG (THHN)

6. Turn on the circuit breaker that supplies power to the NEMA 14-50 outlet, NEMA 6-50 outlet, or hardwired electrical connection.

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.
