Adapter to use 240v Stove outlet for charging?

[FlasherZ]

In newer homes, grounds and neutrals must be carried separately with only one high-current bonding connection at the service entrance containing the EGC. Otherwise it must be kept separate and no, they are absolutely NOT exactly the same. It's the number one confusion for those trying to understand the NEC - the difference between "grounded conductor" (neutral) and "groundING conductor (ground) and the myth that neutral and ground are the same thing.

With that said, as noted it's generally safe. There are fault conditions that carry more risk of shock by using neutral as a ground, usually having to do with that neutral becoming a path to ground for other current in the home. But good design has relegated thus risk to minimal.

Use the adapter for EV charging only, you'll be safe.

Thank you for the explanations and details on this.

I got the adapter today, and tried to set things up for charging from the stove, but unfortunately, in the end, I was just a few feet short of reaching the stove outlet !
I knew it would be close, but was hoping

If only Ford had a passenger side option for hookup, it would have reached fine.

So now I guess my question is:

Do they sell extension cords for the Ford Lightning charge cord ?

Of course, I wish we just got the Charge Station Pro in time for delivery, or I wouldn’t be going through these hoops.
Seems kind of silly to have to do this for a brand new very $ Truck….

but I guess that’s the price for being an early adopter

Yes, you want to look for a 240v/50A RV extension cord in the length you need.

Here’s one 10 feet $78:

How much do you drive every day? You should get 20-30 miles overnight on 120v. DC fast charge on Sunday, add back a little each night on 120. Not great long term, but you’d hate to spend $200 on adapters and extensions if it’s just temporary until FCSP arrives

Thanks again for the info.

I found one by Camco on Amazon. Looks to be good quality.

This should set me up for now,
and I can keep it as a backup in case I’m traveling to someone’s house that doesn’t have charge options nearby, but has a stove/ dryer ( in a pinch! )

Thanks, I took a look at that one and decided to pay a little more for a longer one by Camco.
Again, thanks for all the advice/ help

I was thinking the same ,
but I had such a bad experience traveling a few hundred miles this weekend,
dealing with so many non-functional EV charging stations, and going way out of my way to get the charges I needed,
I’d rather pay a few bucks to be over equipped at this point.

After spending so much money on a truck, I hate to be held captive by SunRun, not knowing how long I’ll be at their mercy to get my charging set-up at home established.

Plus, this will give me a backup when traveling to friends who might not have good charging options nearby

The manual for the evse should have stated that you shouldn't use extension cord. Also one may wish to get a gfci breaker for their use and be sure to have 125% more breaker than load.

Why not call a local electrician?

I have an electrician in the wings,
just waiting for the SunRun folks to mail me the Charge Station Pro.

To make it cost efficient, he wants to do the install in one visit, otherwise I might have had him come already to set up some temporary hookup

It's okay to use an extension cord that's rated for the load. I had to make one to charge on a 6-20 outlet that wouldn't reach. Just don't string together multiple extension cords.

New code in 2017 says you need a GFCI breaker on a receptacle that was installed for an EVSE, but not a hard wired one. No need to retrofit a GFCI breaker to your stove circuit. There is a GFCI device inside the mobile connector as well that can interfere with the GFCI breaker and cause it to trip so it's kind of silly to have this requirement in the first place if you asked me.

They made it a requirement because it's a receptacle (high current at that) typically in a wet area. Even though portable EVSE's are required to have ground-fault circuitry, they want to prevent other shocks.

Not to mention that it's WAY too easy to grab a NEMA 14-50 plug by the prongs if you have gorilla hands like me.

Thanks again for the help everyone. I got the setup working now, and it’s a piece of cake.

I went from charging 2 miles per hour from the standard wall outlet,
to 12 miles per hour off the stove outlet.

What a difference!! No wonder this cord is so thick.

I can see this coming in handy someday again if I’m somewhere without good local charging options, and I can use this to either hookup to a friend’s stove or dryer, or find an RV site perhaps.

This will work great Until the Charge Station Pro shows up, and I get all the permits needed, and then get it installed by a local electrician. And this avoids spending all the time finding, driving to and waiting for the charge at a Fast Charging site.

Nice! Been there. It's kind of a hassle but still satisfying to make it work.
