Nema 1450 vs 650

[Aferreira613]

Is there a difference? Is there a benefit to one over the other?

A 14-50 has two hots, a neutral, and a ground. A 6-50 just has two hots and a ground. Since most EVSEs don't use the neutral anyway, either will work fine to charge your car. That being said, a 14-50 is more common and is the plug type on the EVSE that comes with the MME.

14-50 will be more common to EV's. But the only real advantage otherwise is 14-50 CAN offer 120v circuits out of it while 6-50 cannot because of the lack of a neutral wire. Paying for install 6-50 might be cheaper because it needs 1 less piece of copper.

FYI-
A JuiceBox EVSE plug-in gives you a choice of either 6-50 or 14-50 plug.

I guess Enel-x thinks there is no difference for their 32A or 40A EVSE.

ChargePoint also offers their Home Flex in a choice of plugs. Plus, most 50 amp RV hookups will be the 14-50 style. Not that you would take your home EVSE to a campground, but hey, you never know. Ha ha.

6-50 is cheaper to install since it doesn’t have a neutral wire. Downside is you need an adapter if using the mobile charger. I usually put in 6-50s on new installs since that’s the direction I see the industry going to save wiring costs (the neutral is not used, so it’s a waste of copper for an EVSE). Hopefully the mobile charger will come with a 6-50 plug someday.

My EVSE came with a 6-50p so I installed a 6-50r. That said, most EVSEs have a 14-50p these days, so the 14-50r is most likely going to be your choice by default. ?‍?

I want the ability to use either the Chargepoint home flex or the provided Ford charger. Since the Mach e charger uses a 14-50 that's what I'm installing. So I can use either charger if needed.

Saving the cost of one strand of copper didn't change my logic for the 14-50

Just my reasoning.
