Now that I have a delivery date and VIN I started to look more serious at charging details at home.
I was not concerned, because I have 10-2 30amp Plug (3 wires) in the farthest corner of my Garage for a Heater I use once in a blue moon. It has a L6-30 (Locking 3 Pin Hot Hot Ground).
I saw the wide range of adapters and never thought twice I'd have an issue.
Turns out Tesla makes a 6-20 Adapter and 6-50 Adapter but for some dumb reason no 6-30 adapter.
They offer a 10-30 (which should be illegal because it's Hot Hot - Neutral with NO GROUND).
They offer a 14-30 (which is 10-3 (4 wires)) and is Hot Hot Neutral and Ground. But I have no Neutral.
Yes I know Neutral is the same as Ground but it is treated as a separate line. And you never pull current over a ground.
There is a company that makes a Tesla Adapter for 6-30 and L6-30 but both are out of stock.
I've seen lots of folks go through several adapters to get there which is costly and every connection adds more fault points.
So it's obvious the system doesn't need a Neutral since they have a 6-20 and 6-50 adapters (both are Hot Hot Ground - nothing needs 120V neutral).
Turns out my heater outlet is a little bit of stretch so I'm gonna daisy chain off it for a closer outlet for the car.
It is really bad to use a 6-50 outlet on a 10-2 wire (code wise) and if you use a 6-50 Tesla Adapter the car some how must know it can pull 80% of 50 Amps and overload the 30 amp circuit. There should be nothing -50 or -20 in the circuit path that is inherently 30 amps.
I was thinking of buying a 14-30 adapter from Tesla and cut the plug off and put a 6-30 plug. Which I think is what the 3rd party company did. But I don't know where in that adapter Tesla signals how much current to pull.
So then a lightbulb went off. All I need to do is install a 14-30 outlet and NOT connect neutral (Just Hot Hot and Ground).
That's all the 6-20 and 6-50 adapters could pass through.
This probably doesn't meet code, but wouldn't be dangerous. Anything that needed that functionality just wouldn't work very well.
My only concern is the Tesla might check if Neutral is there if it's supposed to be (even if it doesn't pull current on it).
I highly doubt it does.
So my plan is to daisy chain another outlet off my 6-30 outlet (with more 10-2 wire) put in a 14-30 Outlet and leave Neutral unconnected. And buy the Tesla 14-30 Adapter. This will be cheap, safe and just slightly grey code wise.
My main panel is only 100AMP and pretty darn full so I don't want to add another circuit.
Has anyone done this? Or know how these adapters work?
