Need portable charger adapter advise.

Wed Jul 22, 2020 9:17 am

I just got a 2020 SL Plus. Our home had a 240 outlet in the garage so I figured I could plug in the portable charger. However, the outlet had 3 slots and the charger has 4. I found an adapter but was asked if I can set charting limits for the Leaf.

Need advise please.

Thanks,
Matthew.

You need to look at the breaker to see how many amps the garage 240 circuit can handle. Then multiply that by .8 to get the amount of continuous load it can handle. If it is a 30 amp circuit, then you should NOT use the Nissan dual voltage EVSE on it, because the car will draw 27.5 amps - too much for continuous use. If the circuit is 50 (or 40) amps then you can have the correct plug installed in the outlet.

Do not know what country you are in, but in the USA you need a Nema 14-50 receptacle.

40 amp min circuit, 50 amp preferred with appropriate size wire for the length of the wire run.

with the Nissan EVSE you can not set the current limit.

I am trying to post a picture of the circuit breaker...I am not an electrician so I am clueless...but it's a double breaker, each says 25 on it. So is that 25 or 50?

Which outlet from https://en.wikipedia.org/wiki/NEMA_conn ... d_pins.svg is it, assuming you're in North America?

'13 Leaf SV w/premium (owned)

Congrats. The SL Leaf is a great car. Once you know what your max breaker current is we can recommend variable current EVSE’s if needed. Hopefully your breaker is minimum 40 amps and you are good to go with the stock EVSE that came with the car.

In the USA and the outlet is the 6-15 or the 6-30...that looks like two straight eyes and a nose.

That would be a 25 amp, 240 volt circuit breaker. You can get a wall mount or cable type charging station that can be set to 20 amps, which is the most you can use with that circuit.

On the old standard a 25 amp breaker was allowed to protect 12 gauge wire.
Or even worse a 10 gauge aluminum wire.
If that's the case and you plug in a 6.6kw charger the breaker won't trip and the wire will likely melt.
It calls for a "40 amp circuit" because that means 8 gauge wire will be used in the circuit.
Have it checked by an electrician.

+1 on having an electrician check it out. There is no guarantee what wire is attached to that breaker but as Lefty said, it's a 25A/240V breaker so the most you can run on it is 20A, due to the 80% de-rating required for continuous loads. It is possible the wire has a higher (or lower, although that would be a code violation....) current rating than either the receptacle or the breaker so I'd get someone knowledgeable to take a look at it to see what you have.

The bottom line is that the Leaf charger and the Nissan-supplied EVSE - aka the charging cable - assume an 35A+ /240V circuit. There is nothing in them to detect or modify this requirement, so you need to either upgrade your 240V circuit in the garage or get a new cable that can be set to the lower ampacity that your circuit can handle, once you find out what it is.
