I'm in the process of building a new curbside charging station to replace my current one, which was designed for charging my Volt but has been also been set up to work with the Model S. Now that I've used it for more than a year, I want to make some important improvements that will ensure that it's more convenient to use with my Model S when it's delivered in the spring. The set up will basically be the same concept -- a Hubbell pin and plug system that will make it portable so I can move it from the curbside when it's not in use. However, this time I'll be using a 7" wide bollard cover with a lockable hinged door. That way I can install the UMC permanently inside the bollard so I don't have to keep plugging and unplugging the 14-50P connector and hanging the UMC on the side of the post, where it's exposed to the weather. I can also keep the cable inside the bollard and extend only what's needed to reach the Tesla when I want to charge. The cable will thread through an opening at the bottom of the hinged door. The inspiration for this approach came from this product in the UK called StreetServ. I've already ordered an extra UMC from Tesla for this purpose. My concern is about direct wiring the UMC. To do this I'll have to cut the adapter end off the UMC and direct wire the leads to the Hubbell plug and its 240v 50 amp connections. The actual wiring should be easy to do but as I've not seen the adapter end of the UMC I'm not sure how it's set up. I assume it must have a least three pins, one for ground and the others for neutral and hot. Am I correct in this assumption? I know this will void the warranty but I'm not concerned about that. Any thoughts or advice? A photo of the end of the UMC without an adapter attached would be much appreciated. I've assembled all the materials for this and will begin work in a few weeks.
