Why go wild on the outlet and then go minimum on the EVSE?
Get matching equipment.
3. You need to understand the physics of it: an electric device draws as many amperes as its designed to use. Think of a long jump athlete: he jumps as much as he can and making a bigger sand pit will not make the athlete jump further. On the other hand if the pit is too small he will land on hard ground and break his ankle.LeafSL14 wrote:

4. Is a DC Quick charge something that could be installed in a home? Not needed, but just curious because I can't find much on it.
The outlet is going to be installed about a foot away from the breaker, so I figured I should future proof this since it shouldn't be much of a difference in cost, but let me know what you think. The house is newer and built last year. Images below
Thanks in advance!
But why go through the expense of adding a second circuit when he can already make the first circuit large enough to charge two EV’s at 20 amps each if necessary?smkettner wrote:So add a second LCS-30 on its own circuit.

I agree a 30 amp circuit with a hardwired ClipperCreek LCS-30 charging at 24 amps should serve the OP fine even if OP upgrades to a 300+ mile vehicle in the future.
It doesn't cost that much more to wire a 50 amp circuit up front (assuming the capacity exists), and a lot more to have to re-do it if the OP desires a higher capacity in the future.
Really does not matter.... until it does. Will 2x 50 amp circuits be allowed on that panel?
And if he had gone with a 16A EVSE as he was considering doing, that would have been a dangerous combination. Kudos.Fortunately the OP saw it my (and others’) way and is going to go with a 50 amp circuit
What crazy adapter you using to plug two evse into a single NEMA 14-50? Or do you add a subpanel? Good grief.RonDawg wrote:But why go through the expense of adding a second circuit when he can already make the first circuit large enough to charge two EV’s at 20 amps each if necessary?

Uh, you seem quite concerned with matching breaker size to load. Tell me, have you swapped out many (or any) of your 15A/20A house hold breakers because they only have lamps or cell phone chargers that draw 10% to 15% - or less - of breaker capacity?metricus wrote:EXCEPT: if you install a 50A breaker and something goes wrong with your device designed for 27A the breaker will not protect it and you may damage your device or even cause a fire. Remember that all wires INSIDE the charger are sized to 30A.LeafSL14 wrote:

it is always a good idea to design the circuit EXACTLY for what it will do. My circuit uses 40A wire to comply with code but I installed 30A breaker such that it trips faster if the current exceeds 27A.
I built my own as it was cheaper than purchasing one made but this:smkettner wrote:What crazy adapter you using to plug two evse into a single NEMA 14-50? Or do you add a subpanel?
