    Thanks! The idea of a "gas pump in every home" scares me a bit when I read of all the kludges that are accepted with home electric installations and I'm happy to help guide others here.
    As you know, the problem with these kluges is that they frequently get out of the "lab' environment and to folks with less knowledge. Even good labeling frequently doesn't prevent dangerous usage. One reason I like the extension option (#12 would be my preference) is that it makes explicit the expectation both need to be plugged in.
    Yes. I've seen more than once when someone has found himself an adapter cord and used it inappropriately.

    The biggest thing I can tell everyone is that if your insurance company finds you were using a) non-code-compliant installs and/or b) non-UL listed appliances / cords / etc., they may not cover your loss -- even if it had nothing to do with your charging. This is because they can make the presumption that if you didn't use compliant installations for your car, you didn't use it elsewhere as well.

    BTW, I kind of guessed the UMC used the adapter to select current (how else could it know wire gauge!). It's a shame it selects 80% maximum. In my case I connected a 14-50 with #6 within 18" of the main panel to a 50A 2-pole breaker. The breaker is connected to a separate meter (SCE provides a better TOU rate with a second meter) I really should be able to get 50A no problem (assuming the UMC was properly rated).
    It's a code issue. Any use greater than 3 consecutive hours is rated as a continuous load, and when continuous loads are used the circuit must be sized at 125% (with a few exceptions, where *every* device -- wire, junction box, breaker, etc. -- is rated for 100% duty cycle). Allowing it to be overridden is just asking for a lawsuit. Should you want to do this, your best bet would be to take the J1772 path and build a larger pilot signal.

    I'm wondering if I can make a short cord for daily charging and simply leave the 20ft cord in the car for on the road charging.

    Does anyone know ( possibly someone lucky enough to already hane their S) if the charging cord has any additional circuitry necessary to monitor charging? Can I make my own 5 ft charging adapter?

    You may want to look at the following websites Control Module - EV Charging Stations, Electric Vehicle Supply Equipment (EVSE), and Time Attendance or Smart Electric Vehicle Charger & EV Charger Solutions - EVSE LLC for charging stations.

    Has anyone have/bought/made a spare charging cable for 240V/50A 14-50R? I'm amazed that TM doesn't sell a spare since one ships with every car.

    and I hope it's cheaper than the Roadster UMC at $1500 Universal Mobile Connector - Available in North America Only Tesla Motors

    I parked on my UMC on very sharp rocks and was afraid I almost cut it! fortunately it is ok and just squished. I want a second one to leave at my house. I can't imagine it should cost as much as a HPC though.

    ... yet.
    Please note that the connectors sold through our online store are for the Tesla Roadster. Model S charging options will be released at a later date.

    FWIW, and I'm sure this isn't guaranteed pricing, the salespeople I've talked to at Tesla said that an additional UMC would be $500, with each "dongle" (14-50, 6-50, 14-30, etc.) being $45. So yes, cheaper. Assuming the pricing stays about the same, I'm getting a spare UMC and possibly quite a few dongles.
