I am sure this has already been posted, however, I searched and could not find the answer. I am awaiting the arrival of my P85 and am trying to find the optimal location to install my 40a outlet. How long is the charging cable for the MS?
The UMC cable is 20-feet long. See the Specifications here: https://www.teslamotors.com/sites/default/files/blog_attachments/mobile_connector_manual.pdf
I would install the NEMA 14-50 plug near the garage door opening so that you can charge in or out of the garage (when buddies come over and need a charge, etc).
