NEMA 14-50 or 6-50 for garage charging?

[GHammer]

I am NOT a fan of the screw directly into the wire. So what other options do we have that are cost effective?

Use ferrules?

Hubbell seems like a reasonable solution for the 6-50 at least.

These suggestions of "you never know if a neutral might be required some day in the future" are utter B.S. There would never be any use for that. The purpose of a neutral is so you can have the two separate voltages of 120V and 240V in the same device. Car charging will always want the high voltage and won't have any use for lower AC. They probably will need to create a little 5V DC system for electronics and LEDs, but that will have to be created from a transformer on the circuit board anyway, and can be done from the existing 240V AC input just as well as an otherwise useless 120V. There would not be any purpose to using a 120V supply in an EVSE. And it doesn't fly to think that some day all connections might require dual voltage. There will always be some circuits that are just for straight up high power applications--mainly heating--like electric water heaters or whatever that use only two hots and ground.

That the Hubble I bought two of. They have the screw on the wire. Not the clamp type. Just because it is a Hubble does not mean it has the clamp type I found out.

Good data! Thanks!

Incidentally, it looks pretty identical to the Bryant one (just like the Hubbell and Bryant ones are very nearly identical).

But do note, there are slight differences between even the 14-50 Hubbell and Bryant receptacles. They clearly are still trying to make The Hubbell the premium brand.

So bummer. I wish we could come up with a more robust 6-50 (without having to resort to ferrules).

What uses a 120 volt 50 amp 5-50? Or even a 5-30?

The only real application of dual voltage plugs is connecting RVs, as those can have both 240V and 120V appliances. Electric dryers in North America use dual voltage too, but in Europe they work just fine with 230V only.
