Yes, exactly. It's like you were reading my mind!

That could cause a fire if you just put a 10-30 amp adapter on a NEMA 14-50 plug, then plug it all into a NEMA 10-30 receptacle.. If the car is still thinking to pull 40 amps, yet the adapter is daisy chained into a NEMA 10-30 (30 amp) receptacle, then it will get hot and could cause a fire.

The beauty of the Eberhard RFMC design is that this cannot happen. The diode in the plug adapter communicates with the micro controller in the box. This prevents the car from pulling more than is possible for the NEMA receptacle that you are plugged into.

If you are just putting a plain adapter on a NEMA 14-50 plug, be very careful about the amps you pull via the VDS.

The standard MC240 from Tesla is only 30 amp capable right now, so you can't really over-draw through it. (e.g.: NEMA 10-30 to 14-50 to MC240 is probably OK).

When they finally offer a 40amp capable version people will have to be more careful.

We have designed a new box for the Roadster Foundry Mobile Connector. It is a smoother look and is more waterproof.

James,

is it lager than the "old" one?
I am sure many want to know. Besides the technical features, one big advantage of the RFMC is that it is/was so much smaller than an MC240.

It is the same size as the previous one. The dimensions of the sticker are just off on that concept photo. The new design is really good and slightly more waterproof by reducing the number of penetrations into the box.

It is 1/3 the size of the big bulky MC240 from Tesla.
It also has more adapter options, will work with European electric standards and will do any voltage and amperage from a household outlet all the way up to 40 amps.

We think we could make it do 240 volts / 48 amps on the Tesla VDS when plugged into a 50 amp outlet. But those silly NEC rules are holding us back from offering that to the public.

At 240 volts and 48 amps, that is 68% of what the HPC provides at home.
A 5 hour recharge from empty while on the road with the MC. That would be really useful.

James, that new box should also have a way to mount it on a garage wall for permanent garage installations.

Looks nice.

I guess that makes the ME boxes super rare now.

Collector's items! With the name on it of the founder of Tesla Motors. There are, what, only a dozen, maybe two, in existence? I've got one of them.
