I've seen nuisance tripping with "series GFI's", when a GFI receptacle is connected to the load side of another GFI receptacle. That said, thousands of new hair dryers with GFI plugs are used with GFI receptacles every day. I know that I've heard the Roadster's UMC was pretty sensitive to GFI circuits. So there's an increased chance of a nuisance trip or a ground fault indicator. Technically, there should be nothing wrong with it.

Technically, according to the NEC, EVSE equipment cannot be cord-and-plug connected for outdoor locations. That said, I believe Tesla has engineered it to be reasonably weather-resistant (not weather-proof!)

Mine is outside and mostly uncovered. I haven't had any issues with the UMC getting wet in the rain. The charge port on the car is always under cover, however. The cover on the outlet box also keeps the plug out of the rain. I've attached a pic showing my set-up on a rainy day.
What I've seen with the Volt's EVSE is the following:
During boot-up, it sends a little current down the ground conductor for 1 to 2 seconds to test whether there is a secure and reliable ground present. If there is a GFCI in line that happens to be quite sensitive, it trips.

The outdoor box is the same I am using except indoors, in my garage.
Question ... the plate on top, held on with four screws ... do you find it a bit odd that it has no seal ... water can run in the top? Did you mod yours to prevent that?
I need to get a plug installed within the next few months. Tesla Obviously suggested I contact solar city. However, I have an electrician that I use for most of my home projects. If I call him, what exactly Do I ask for? A NEMA 15 – 40? I do not have a garage. My car will be parked at the front of the driveway closest to the house. The wall at the front of the house is just above my dryer below in the basement, not very close to the circuit breaker box.

Jenni, you want a "14-50 outlet, on a 50A circuit breaker in a weatherproof RV style enclosure", as seen in the very first post on this thread. Home Depot actually sells those outlets / enclosures in most stores, Lowes might have it as well. The electrician will have to run wire/pipe in your basement or outside around the house to reach from the circuit breaker panel to close to where you park. The UMC that comes with the Model S is 18 feet long, so have him install the outet within 18' of the rear drivers side tail light.

Sorry to turn the question around, but I suggest you invite the electrician to take a look at your existing home wiring, show him the Tesla supplied UMC, and see what he recommends.
If you do not yet have the car and the UMC, show the electrician this: http://www.teslamotors.com/sites/default/files/downloads/universalmobileconnector_nema_14-50.pdf
So, what if the breaker box is clear on the other side of the house down in the basement? I don't think I want to run all over the place every time I park or drive off.
Could this solve the problem:

Jenni, you can also go with this one, this is what I installed outside: 50, 30, 20 amp Surface Mount RV Power Outlet Box - RV Park Supplies
It has the advantage of the lid opening "up" and then you can mostly close it over the 14-50 while its plugged in, it also has a TT-30 which is a 30A 120V outlet for those "pop up" RV trailers (could come in handy one day), it's about the same price as well, but you need to order it and they ship it to you. They are in NY, so the shipping will take a few days before you get it.
Oh, wow, 250'! My house width is 35'. We are going from one side of the basement to another, inside the house until they come through for the outdoor outlet nearest my driveway. Sorry if I was being confusing.
Okay, my vision of your setup was very different. $1300 seems high for what you describe. I paid $900 in total for running a #6/3 line over the wide garage door, running a 120 V line for a four outlet receptacle next to the 14-50, and running a second 120V line for an outdoor light plus a switch for the light. I supplied the light ($250), so that's not included in the $900. Two electricians took about ninety minutes to complete the work.
