DO NOT, UNDER ANY CIRCUMSTANCES, plug an unmodified 120v evse, such as the one that came with your Leaf, into a 240v outlet.mikelb wrote:I have a dryer outlet that is 30A, 250V. Is it safe to charge by unplugging the dryer and plugging in the EV when I need to charge, and plugging in the dryer when it's needed? Are there any safety concerns?
That's absolutely against code. Only one 240V device allowed per circuit. "Remembering" to never run them together is subject to error either by forgetfulness or perhaps visitors "helping out". And "the circuit breaker will save me" is not the right way to look at it.Graffi wrote:As was already stated, you can get an EVSE rated 24 amps or less, or update the circuit to 40 amps and use a 30 amp EVSE. This would be my choice, as long as the wires will handle 40 amps. Just replace the circuit breaker, then install an additional outlet next to the current one, using the type of outlet that the EVSE uses. Leave both the dryer and the EVSE plugged in all the time, but NEVER use the dryer when the EV is charging.
Read through the information provided re: neutral vs. ground is this previous thread:Phatcat73 wrote:Similar question. I have a Bosch 240V 16 amp EVSE and an unused 3 prong 240V 30 amp dryer outlet (considered the old style outlet). The EVSE requires a hard wired connection. I purchased a dryer cord, installed it to the EVSE and found that it works!
However, the Bosch requires 2 hot leads and a ground, whereas the 3 prong outlet has 2 hot leads and a neutral.
Is this safe? If not, how is evseupgrade getting around this with their adapter?
That is neither code, nor safe.Graffi wrote:Leave both the dryer and the EVSE plugged in all the time, but NEVER use the dryer when the EV is charging.
