That's a great idea to test the Tesla UMC with a NEMA 5-15P using a NEMA 5-15R to a L6-20P adapter; I didn't think of that idea! that's why I sold the one I made and went with a more easily adjustable OpenEVSE http://www.myrav4ev.com/forum/viewtopic.php?f=9&t=1013Incidentally, with the homebuilt quick240 and the commercial quick220 20A device, you can charge at 16A 240V. The only caution is that many 120V outlets are only 15A but I find outlets in garages are 20A (for example, the outlet that powers the garage door). When I am not sure whether the outlets are 20A, I can limit charging with the EVSE to 12A (or 14A if charging for less than 3 hours).
