This set of homemade electrical adapters has provided, not only plug-in convenience, but has served as an "electrical life line" in obscure locations which have few charging options.  To other Tesla owners, I am not recommending, nor discouraging use of such homemade adapters.  The intention of this post is to document what works for me and what I consider to be a valuable asset.

  2. Regarding your NEMA 10-30(M) to NEMA 14-50 (F) connector - I understand where the two hot wires connect. What is not clear is which connection(s) of the NEMA 14-50 are connected to the Neutral of the NEMA 10-30. My gut tells me connect to the NEMA 14-50's ground, but Tesla's UMC could want both the Neutral and the Ground to have continuity. email 2cybers (at) gmail (dot) com

    1. You're right, the neutral of the NEMA 10-30 connects to ground of the NEMA 14-50. The neutral of the NEMA 14-50 is not connected to anything as it appears the neutral is not needed.
