On Saturday I'm taking possession of my new S 85D, upgrading from a Volt (yeah!). I have this Seiemens 30A EVSE level 2 charger (Amazon.com: Siemens VC30BLKB 30-Amp Bottom Fed VersiCharge Electric Vehicle Charger: Home Improvement) in my garage connected to a 240V outlet wired to a 40A breaker. So I have two options for charging my Tesla: connect to the EVSE via the J1772 adaptor or connect directly to the 240v outlet. Because I only have a 40A breaker I cannot charge more than 30A so I am not sure it matters whether I use the EVSE or not? Thoughts? tha k you!
