Load Sharing Use and Setup

You just installed and added your second of two JuiceNet enabled devices, but only have one electrical circuit.  Good news, the JuiceNet servers allow you to share one electrical circuit safely while charging both vehicles.

For your electrician:

Please note the following: You can only have a 50A circuit for Pro 40 load sharing, and a 100A circuit for pro 75 load sharing (per load sharing group).

For load sharing, these work for splicing the wires together so that you can have 2 outlets on one circuit. I suggest a junction box between the two outlets for ease. 

---
This insulated, multi-cable connector block is big enough or either the #6 or #4/3 size wire. When sharing a 100A circuit they would need the #4 and up (for 2 pro 75 units only).  You will need two of these, one for each hot leg, and you should be able to use a large wirenut or similar connector for the grounding wire.




For you:

Once your electrician has them wired up and connected to WiFi, please add them to a new Load Group in your dashboard. It will allow a combined output per the NEC 125% rule. For example, a 50 amp circuit for two Pro 40 units would split the available 40A.

To set up a Load Sharing Group, follow these steps:
Go to dashboard.emotorwerks.com and login (same as your app login) and under My JuiceNet select Load Groups.
​

Select + New Load Group and give it a name and shared amperage rating (this is 80% of the circuit breaker)
​

When selecting the amperage limit for the group (this is remembered even if offline), please follow this chart:
100A circuit breaker = 75A Maximum Current (A)
50A circuit breaker = 40A Maximum Current (A)
40A circuit breaker = 32A Maximum Current (A)
30A circuit breaker = 24A Maximum Current (A)
20A circuit breaker = 16A Maximum Current (A)
​

Now click on the group name to add the JuiceBoxes in your account

​​

Select from your list, if you have 2 JuiceBoxes, you will see 2 to select. Check them and select "add selected."
​
The boxes will default to 8A, and will start there, and they will check to see if it is sharing so as not to trip the circuit before it gets the server command. When one car is charging, it will get full charging capabilities. When the second car plugs it it will start at 8A, then ramp up to 50% and the first car ramps down to 50%. As one car tapers off, the other will increase so that all available amps are able to be used as needed.

That's it, please note that if your server connection is lost the Load Share group will default to the offline amperage rating of 8A for safety.
