Level 2 Charging at Home Help

Tue May 14, 2019 2:01 pm

Hey everyone,

Just bought my first EV a little less than a month ago (used 2014 Leaf SL). I'm looking to install a 240V outlet in my garage, but that's as far as I have gotten cause I need help with the stuff below lol

1. Should I install a 20-AMP, 30-AMP or 50-AMP Outlet?

2. Should I get a 16A or 32A charger? I'm seeing a ton of these on Amazon even though they all seem to be the same with some extra twist.

3. Can too much AMPs destroy anything or should the charger be able to control that?

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!

Your car can take up to 27.5 amps and you need at least 40 to meet code requirements at that rate, so if you want full charging speed I suggest a 40 amp circuit, with a 30amp charging station. You can also go with 50 amps and a 40 amp charging station, as "future proofing" in case you get a faster-charging EV in the future.

Given you will install the outlet right next to the breaker panel and you have the capacity, I would suggest the future-proof route of installing 50A circuit with a NEMA 14-50 outlet. This will let you charge at up to 40A. Any EVSE plugged into this will only deliver the maximum to your car, so that's not an issue at all.

Second this. I had a 14-50 installed rather than try to just get by with a dryer outlet.

If you have the capacity, I also recommend going with a 50 amp circuit (which will allow up to a 40 amp EVSE). A couple of reasons for this, even though your Leaf will not be able to take advantage of such a capacity:

1. As battery sizes increase, on board charging speeds will increase as well. Teslas can already charge at 40 amps IIRC. My eGolf even though it only has a 24 kWH battery already can charge at 30 amps.

2. It will not be unusual to have two EV's in the future. A few folks here already do. Having a 50 amp circuit will allow 2 EV's to simultaneously charge at 20 amps each.

Same as above, I got a 14-50 outlet wired by an electrician, that n case I move or need to change EVSE
The Juicebox I bought delivers faster than my Leaf can accept, but it will only draw as fast as it needs. I have let someone with a BMW charge and it was twice as fast. It had some features I like and customer service was exceptional. I spoke to a human in California who answered my obvious (in hindsight) questions when I set it up.

The problem with a 40a circuit is they don't really make a 40a outlet, they jump from 30 to 50 and while it's code to run a 40a breaker to a 50a outlet, it's not code to run a 40a circuit to a 30a outlet.
Personally if running a 40a circuit to a 50a outlet(such as the common EV outlet 14-50) I'd probably label it somehow as being on a 40a circuit.
Best to just run a 50a circuit IMO :)

Future proof? Outlet? Install a NEMA 6-50 outlet and plug in a Clipper Creek HCS-50 with 6-50 plug.

Right. Just have the Nissan EVSE posted upgraded here; http://evseupgrade.com/?main_page=index&cPath=1

Have a 40 amp 220V service installed with L6-30 receptacle. You can also buy a number of adapters to carry in the vehicle with the EVSE
to charge at various locations.

This always happens. Someone posts about having a circuit installed for their 6.6kw (or less) charger-equipped Leaf, and the next thing you know 50 amp circuits are being pushed. Not everyone needs to "future proof" their garages. It's an option, not the only sensible thing to do.
