Yes. To avoid complications, simply request a NEMA 14-50R outlet installation with a 240V, 50A circuit. Make sure you request that the outlet is installed within one foot of where you want your JuiceBox located.
Hardwired JuiceBoxes use the following wire gauges within the conduit:
32A/40A:
| Color | Signal | Gauge (AWG) |
| Red | L1 | 6 |
| Black | L2 | 6 |
| Green | Ground | 8 |
