120v operation with the current 40a Advanced Kit

I think I know the answer to this, but I wanted to double check before ordering.  


Will I be able to use this kit with a regular 110v nema 5-15 household outlet for the time being until I get 220v installed in my garage later this year or next year?  I'd like to buy one charger now and upgrade it to fit my needs.


Sorry if this is a newb question.  I have some wiring experience from building guitar amps and various automotive projects, but no experience with circuits like these.


Thanks.


Yes. the Advanced series will take whatever voltage you provide to it from 90 up to 264. 120v, 208v and 240v all work great.

 Hi,

I just bought an Advanced OpenEVSE kit.

Am going to make the unit portable with a 14-50 plug.

For a 14-50 connector to 5-15 plug, exactly how is an adapter cable wired?


Thanks and good health,  Weogo


NEMA 14- 50 Ground to NEMA 5-15 Ground

NEMA 14-50 Hot 1 to NEMA 5-15 Hot 1

NEMA 14-50 Hot 2 to NEMA 5-15 Neutral

NEMA 14-50 Neutral NOT CONNECTED.

Thanks!


That's what I figured, just wanted to make sure.


Good health,  Weogo


 If you're feeling more wealthy than handy, it looks like you can buy these: http://www.corddepot.com/shop/electric-vehicle-power/conntek-ev14400t-5-15p-to-14-50r-ev-adapter/

 Hi Tony,
 
That's a nice looking assembly.
I do live audio production and build a lot of cabling.

The reason I originally asked the question is one video showed
tying the ground and neutral wires, which I understood to be a no go.
I've searched but can't find the video to post a correction.

Thanks and good health,  Weogo

@OpenEVSE Support, thanks for the 14-50 to 5-15 wiring info. I am in a similar situation. I plan to use 220V at home for faster charging, but there is only 110V at work. Can I simply solder one 14-50 cable and one 5-15 cable at the input end of the openEVSE charger? Will the openEVSE charger auto detect the input voltage? Thanks a lot.

Hi George,


Please clarify, are you talking about having a 'Y' cable, with one leg having a 120V plug, and the other a 240V plug?

This would not pass code, as you would have a live connector exposed.


I suggest putting a 14-50 on the end of the cord.

Then make a short adapter cord with a 14-50 receptacle going to a 5-15 plug.


Additionally, a solid screw connection can be more durable than soldered.

Soldering can create a stress point where the wire can break.

Most aircraft wire connections are high quality crimps or other mechanical fasteners.


Yes, OpenEVSE will auto-detect the input voltage.


Thanks and good health,  Weogo


Yes, I was thinking about a 'Y' cable. Thank you for the explanation. I will make an adapter cord then.
