Wiring and Installation requirements

Kris -

What you need to know about the installation

Plug in Installation

Many stations plug into your home or office via a NEMA 14-50 electrical plug.

When hiring an electrician, request that they install a NEMA 14-50 receptacle for the rating of your JuiceBox or other JuiceNet Device (typically a 40A or 50A circuit). Make sure the receptacle is installed within a few feet of where you plan to mount your charging station.

 

Hardwire Installation

If your station requires hardwired installation, ask your electrician to connect the station in a protected, NEMA-compliant enclosure.

 

How do I determine if my station must be hardwired?

The details below should help you determine the necessary wiring for your station. Please consult with your electrician regarding the specific parts needed for your site, but below we’ve also included an overview of the likely materials you’ll need.

 

32/40 amp

Charging Station output (continuous load rating)  32A

Required Circuit Breaker (must be rated to 125% of the continuous load rating) 40A

Example stations: Clipper Creek HCS 40, AeroVironment EVSE RS 32

 

Plug In Installation

- 2 pole, 40A breaker1

- NEMA 14-50 receptacle (NEMA 14-50R)

- #8AWG copper wire with 3 conductors and a ground. If single conductor THHN wire is used, the ground may be #12AWG per NEC 250.122 calculations2

 For an outdoor installation, please add the following:

- NEMA 14-50R outdoor enclosure

- Shade for the unit so it is not in direct sun, exceeding the 90°C mark

1 Recommend against GFI circuit breaker.

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

 

Hardwire Installation

- 2 pole, 40A breaker1

- #8AWG copper wire with 2 conductors and a ground. If single conductor THHN wire is used, the ground may be #12AWG per NEC 250.122 calculations2,3

For an outdoor installation, please add the following:

- NEMA rated outdoor junction box with gasketed cover 

1 Recommend against GFI circuit breaker

2 Please, only use the pre-drilled opening on the bottom of the box for hardwire applications. We cannot honor the warranty if any other holes are added to the unit.

3 A fusible disconnect may be required within 6' of your JuiceNet device installation, please consult your local code.

 

40/50 amp

Charging Station output (continuous load rating) 40A

Required Circuit Breaker (must be rated to 125% of the continuous load rating) 50A

Example stations: JuiceBox 40, JuiceBox Pro 40

Plug In Installation

- 2 pole 50A breaker1

- NEMA 14-50 receptacle

- #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 calculations2

For an outdoor installation, please add the following:

- NEMA 14-50R outdoor enclosure

- Shade for the EVSE so it is not in direct sun, exceeding the 90°C mark

1 Recommend against GFI circuit breaker.

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

Hardwire Installation

- 2 pole, 50A breaker1

- Junction box to wire into from the JuiceBox2,3

- #6AWG copper wire with 2 conductors and a ground. If single conductor THHN wire is used, the ground may be #10AWG per NEC 250.122 calculations2 

For an outdoor installation, please add the following:

- A watertight/weatherproof junction box or enclosure

- Shade for the EVSE so it is not in direct sun, exceeding the 90°C mark

1 Recommend against GFI circuit breaker

2 Please, only use the pre-drilled opening on the bottom of the box for hardwire applications. We cannot honor the warranty if any other holes are added to the unit.

3 A fusible disconnect may be required within 6' of your JuiceNet device installation, please consult your local code.

 

75 amp

Charging Station output (continuous load rating) 75A

Required Circuit Breaker (must be rated to 125% of the continuous load rating) 100A

Example stations: JuiceBox Pro 75

 

Hardwire Installation Only

- 2 pole, 100A breaker1

- Junction box less than 3’ away to attach the pre-wired pigtail into

- #3AWG copper THHN wire with 2 line conductors and a #8AWG ground per NEC 250.122 calculations2,3

For an outdoor installation, please add the following:

- A watertight/weatherproof junction box or enclosure

- Shade for the EVSE so it is not in direct sun, exceeding the 90°C mark

1 Recommend against GFI circuit breaker

2 Please, only use the pre-drilled opening on the bottom of the box for hardwire applications. We cannot honor the warranty if any other holes are added to the unit.
