I bought a new Model Y recently and was planning to install NEMA 14-50 Receptacle for the Mobile charger. I saw many posts and youtube videos regarding this. Now, it looks like a wall connector is the best option to install.

For Installing NEMA Outlet for Mobile Charger – I have to buy NEMA 14-50 adapter ($45), Industrial NEMA 14-50 receptacle/outlet (Bryant $50, Hubbell $80 – if available), a box+plate for the outlet ($7) and GFCI 50A double pole breaker ($100 – GFCI required according to NEC 2021 – new requirement). Other accessories are common to both.

For Tesla Wall Connector – Wall Connector Gen 3 ($400), Non-GFCI 50A/60A double pole breaker ($10-$30).

For a Mobile charger – $200 -$225 to Charge Tesla Model Y @30mph
For Wall Connector – $430 to charge Tesla Model Y @ 42mph + You will have a mobile charger in your car as a backup.

The difference is $200 for which we get a mobile charger as a backup (Mobile Charger costs $200). Wall Charger has inbuilt GFCI and has WIFI for future use. If we install a GFCI breaker for NEMA PLUG, the chances of tripping are more and we have to reset it manually to continue charging whereas the wall connector resumes charging automatically.

This is the information I gathered by watching several videos, going through this forum, and reading some articles online.

Please kindly update me if I’m wrong or missing any information. I was planning to install Wall Connector next Week.
