EV Charger question

[olly]

I don't do a lot of EV chargers installs
I am helping my brother in-law install a charger for his new Ford Lightning. SHM. I am only helping because he is family and I really don’t have time for this, one of those annoying situations that's not paid. The charger is the: Ford Charge Station Pro - 80 AMP WALL BOX

1. Is an 80A breaker good? Or should it be sized at 125% for continuous duty?.
2. He has Siemens type QAF2. Do these breakers have adjustment on them?
3. Would you install GFCI if it were in your garage? Is that to Taboo for this site?
4. Spec calls for #3 CU. Its going in FNMC, 1” so I will be using THHN. #4 THHN seems fine to me based on code

Before you report me for a DYI look at my history. This just isn't in my wheel house.
Thanks in advance for reading and any reply's given

You need a 100 amp breaker, and wire sized for 100A circuit loaded to 80 amps, so #3. Plus you must follow the instructuon manual and it also states #3. So you will.need 1 1/4" conduit. Gfci is not required.

He decided to go "green" hahahhahahahaha. He must pay for it to be hooked up properly.

If it doesn't need a neutral you will probably be fine with 1" conduit.

Compared to the gasoline equivalent, yes the F-150 Lightning will generate less pollution over its lifetime. [The impacts will be different, so that requires a judgement as to the tradeoffs involved, but is a pretty safe call assuming the truck doesn't suffer an infant death through collision, etc.]

And yes, you currently pay a premium for that. Most likely the net subsidies are still biased towards the gasoline F-150, but even if not, the electric vehicle market is still maturing, so that's not unexpected.

Just hooked up one of these. No neutral is needed. Don't worry about gfi it's over 50 amps 1 phase. Copper only and it's 75° at 3 awg so double check your liquid tight. There's a wierd kick on the charger too you can't come in straight up or down.

Also….there is a hardware setting that can deprecate the charge rate to 64, 48, 40, or 32 Amps. You are allowed to size the branch circuit based on that setting.

Or he likes the 0-60 time. And/or the using the truck as back-up power for the house.

That backup for the house is a big deal to set up and doesn't come with the charger. Ford has a transfer switch that from what I've seen isn't even available unless that's recently changed. They just only in the past few months got the first orders out.

Yup. Although it can also be used as a portable generator with an inlet and manual transfer setup, without all that.

It is available, but it’s expensive and a PITA to install and get running.
If you have nat gas, it costs less to install a 22 KW generator. Plus, your truck doesn’t have to be home for backup to happen.

0-60 in 4 seconds is not to be ignored!

This guy has a nice description of what is involved

Perfect opportunity to sell the hook-up as a payment service, charging interest along the way.

It's also a super waste of resources.
You know eV's burn through tires way faster, yes? Hmmm, where's all that rubber coming from, and where's all that old tire rubber going?

Why would that be? For a given set of driving habits (acceleration, braking, no peeling out. etc.) why would EVs be harder on tires than ICE vehicles?

 

[synchro]

EV's are significantly heavier than an equivalent vehicle with an internal combustion engine:

Same places all the engine oil and spark plugs for ICE vehicles come and go from?

the ground?

 

[LarryFine]

the ground?

No, back to the source.

The black stuff on roads after bumps is actually shock-absorber oil.

I bet you’re really fun at parties.
