Extension cord for 40A Mobile Charging Cable Kit

[boxerbay]

My thanks to all. I have ordered the Lucid Home Connected Home Charger which is scheduled to be sent out the week of the 15th of January (such as I have been informed by Lucid). In the interim, and as an alternative when I am away from home, I ordered and received the 40A Mobile Charging Connector. The problem is my closest 110v outlet, is approximately 20 feet from where I park my Lucid. I am therefore in need for a suitable extension cord. Furthermore, the question is do I plug in the extension cord to the 110v outside receptacle and then plug in the 40A Mobile Charging Connector onto the car, or do the reverse? Thank you again for your responses.

Don't waste your time. Your fuses will trip. Also 110v charging is super slowwww. You need an electrician to put a nema 14-50 outlet on your wall.

I'd been thinking I might want to be able to plug into friends' 30A drier outlets using the Mobile charger w/30A plug option. For this, I'd been picturing getting a heavy-duty extension cord designed for 30A use (ie with the standard 30A male/female at its ends).

Any advice about this plan? Gauge of cord, being sure the connection between Mobile Charger male 30A and cord female 30A is shielded from moisture, etc.? Is 25' the longest I should consider, or could 50' be workable/safe? I could see limiting this to something like 2 hour sessions, to mimic the maximum time a drier might draw current; seem sensible, or unnecessary?

Also: the warm vs. hot distinction on the plugs, which I've seen mentioned several times.....any rule of thumb where that line is? (eg if can touch it for a full second, it's not "hot"? Or similar, name your time!)

It's a nema 14-50 that draws 40 amps if you get the adapters to run off 30amp dryer it will trip breaker in 2 minutes. I k ow I tried. Ended up sending everything back to amaxon and got an electrician to put the proper 14/50 nema on the wall near the garage door.

14-50 vs 14-30

This is the correct way. 240v 14-50 nema plug. It by the door i run cable u der door and it is looped outside on side of house. I get full charge in about 4-6 hours.

I’m all set at home with a heavy duty 50A plug ready to feed an EV for hours.

On the road, staying with friends for a night or two is the use case I’m exploring for the 30A option. Yes, for sure only the modern 14-30; went thru that with a new drier recently. I’d be using Lucid’s 30A optional attachment to their Mobile Charger, which is designed to just draw 30A and plug into a 14-30. Good to know driers only pull the full 30 (24) for bursts….so yeah, as with any non-EV-designed plug, the “hot tines” test will be key.

(I’d only use the 110 option on the road if I was hanging somewhere for a couple days…)

How about lengths for the 30A cord? Do longer cords (even correctly sized) add significant resistance heat?

Oh ok then yes use the 30amp adapter and then use an RV extension cable with male female 30amp nema ends.

I'm not an electrician but i play one on TV (jk)

My suggestion is to go with the J1772 extension for the reason of getting wet. Those connection are water tightish. Where as any other extension cord of any kind wont be at the joint. In addition as someone pointed out you will be protected by the EVSE's GCFI.
