Does that mean that your J1772 will have thermal monitoring too? If your J1772 mod supports thermal monitoring and passing through the proximity wire to the unit, it would be worth the money over a more typical EVSE.

If I can source the appropriate thermistor, yes. Of course we can pass through the proximity wire, both with our own cable or the Tesla cable. Every JLong is built this way.

The units definitely communicate with each other using a separate wire connection. RS-485 would certainly fit with the twisted pair connection the manual shows.

We finally have these in stock... fully 80 amp compliant J1772. Also, thermal management of the plug temperature.

Tony:

Some logistical questions:

1. If mounting two units, how close to each other do they have to be? Can they be on opposite sides of a 2 car garage in order to charge two cars?

2. If I have a 50A supply, and am charging my RAV at 40A, what happens when I plug in my Volt which can take up to 16A. Does the RAV drop to 24A or do they each drop proportionally to say 29A and 11A?

3. I currently have a Leviton on a 6-50 3 wire outlet. Will it connect or do I have to order an adapter?

4. How many wires are needed to interconnect the two units?

Mike

5. If one of the cars completes it charge, will the other return to full amperage?

(sorry, forgot to include this with other questions)

Here's the installation manual. NOTE: Do Not Use 277 Volts!!! It is referenced on pages 9 and 21 in the manual. There is a misprint about using a 50 amp circuit (rotary knob setting "8") MAX to string 4 units together (page 29, Note 2); that is wrong. It can be at any setting up to a 100 amp circuit.

49 feet, according to Appendix B, page 29. They could certainly be anywhere in any common household garage.

I don't know... the manual doesn't say.

It will be hardwired. If you use the same physical outlet, they will remove the NEMA 6-50R and physically connect the wires together in the junction box. Simple and easy. You would have to set the "master" J-Wall at "8", for a your 50 amp circuit, for instance. The remaining units are set as "slaves" by using position "F" on the rotary switch of EACH slave.

4. How many wires are needed to interconnect the two units?



If appears that two twisted pairs are required, preferably shielded

I'm confident that it does, but the manual doesn't state that.

Looks like a good deal Tony. Now if I could only sell my Leviton. Any offers?

Tony:

Would each unit require a separate 50A breaker or could one breaker supply two units that are connected as master and slave (assume they are mounted next to each other).

You could wire up four individually, each with its own circuit breaker, or just use the 50 amp circuit that you have. Four can run at the same time on ONE breaker.
