No. Not at 240V. If the EVSE offers the Bolt 40A, the Bolt will try to draw 32A from it.

What ga2500ev said. The Bolt will draw 32 amps max and that's controlled by the car, not the thing that plugs into the car (EVSE).

portable chargers and charging rates
Hello everyone. I've got 2 questions: 1. Which portable level 2 chargers should I consider buying, and which should I avoid? 2. When charging at level 1, you can choose either 8 amps or 12 amps. Can you also choose the amperage when charging at level 2? I'm not asking whether I can buy either...

Some EVSE have the ability to set the maximum current they will draw. You may be able to change you draw to an appropriate amount - 80% of 25 amps or 20 amps max.
What is the brand/model of you EVSE? Someone on this forum may know how to adjust the maximum draw.

Incorrect. The maximum current the Bolt will draw from 240V is 32A, regardless of what the EVSE advertises above that. The circuit (breaker, wire and receptacle) needs to support 40A, according to the NEC 80% guideline.
Many brand named EVSEs have variable outputs. JuiceBoxes have software control; while Siemens units have little dials to adjust max current. For about 10 bucks you can buy/make an adapter to use the stock charger.... What socket do you have?
Also 25 amps is generally used for wired equipment like air conditioners. If you can verify the wiring is 10 AWG, you can put in a 30 amp breaker and get yourself a little bit more power. (And if not you could have a potentially dangerous code violation.)
Edit: The circuit could also be de-rated if it is being run through a conduit, so check if that's not the case too.

Yeah something like that would probably work. I'd probably swap out the breaker with a 30A and use one of the 24A chargers. But then, I'd spend a bit more money for a ul-listed unit, like a JuiceBox.
OEM EVSE on 240V should get you about 90 miles a night (8 hr). It draws 12 amps. I have a NEMA 14-50 with a #6 wire, so 12A is a very light load.
This is what I use to conver the NEMA 14-50 to a NEMA 6-20 then NEMA 6-20 to a NEMA 5-15 receptacle.

Adapter for Bolt Charging
That Coleman cable is what I used for mine. Works great...only slight downside is my adapter is pretty short, but I also used a bigger 14-50 end... @Gavinmcc - how well does that 14-50 R plug seal to the cable going in to it? Was it difficult to remove the neutral pin from the plug? Mine...

In your case, you should change charge current of your EVSE side.
If 25A circuit breaker installed, it means you should use max 25A in that circuit.
Contact manufacture of the EVSE how to change max charge current.
Unfortunately Bolt cannot change L2 charging current, while other cars can do.

In the US, you can only run 80% of the capacity when running constant load, so a 20A breaker SHOULD only support 16A. (BTW, I use 20A because not sure we use 25A breakers)

If so, charge current should set 20A by EVSE.
Not sure which EVSE Oleg Orel is using, and his EVSE can set charge current.
Eaton makes breakers in 5 amp increments. As an example, Cutler Hammer breakers (made by Eaton) can be ordered in just about any limit in 5 amp increments, including 25A. I ordered a 125A one for my EVSE project via Amazon of all places. Square D breakers, or Westinghouse ..... also owned by Eaton come in 5 amp increments. Home Depot and the like won't always stock it in all these variants but Amazon is a good starting place. As always, the breakers are rated at 75 degree's celsius for their limit so when you look at amperage tables on the internet, you are not supposed to use the popular 90 degree limit for sizing wire but the 75 degree one.
