![]() Given the wire will be more robust than the EVSE, the breaker should match the EVSE. I'd run #6 which would support 40A at about any expected temperature.Īlso note that while the saying is "the breaker protects the wire", the breaker also protects the EVSE. It would be large and expensive and total overkill. However, I wouldn't bother to run #2 copper wire. Chargepoint’s offering is less vast, with no 32-amp unit on offer. Since outlets and breakers are easy to change but wire isn't, if you are going to "future-proof" the circuit, concentrate on the wire. In terms of overall power, Juicebox offers a selection of offerings depending on your needs with a 32-amp unit (hardwired or plugin), a 40-amp unit (also hardwired or plugin) and a 48-amp unit that is hardwired only it’s also much harder to find and very few retailers cary it. Note there are three parts of the circuit. EVSE won't last forever, so buying more EVSE than you need is like buying a pair of pants for you son that he'll need if five years.) ![]() (Also note that buying an EVSE which supports higher charging than you need isn't that wise. Given cars usually sit for 10 hours a day, and given your commute is 300 miles a week, 30A will give you enough charging and then some. The more amps the less efficient the charging, and 30A will get you about 20 miles an hour. This unit is slightly more expensive than the. The JuiceBox 40 and ChargePoint Flex are truly next-generation chargers with attractive designs, convenient features, and integrated apps that do much. JuiceBox Pro 40 from eMotorWerks is our second pick on this list because of its power, features, and capabilities. I went for the 40 since I wanted the NEMA 14-50P and flexibility to plug in other stuff. The JuiceBox 48 is the same as the 40 except its a higher amperage, which should be hardwired only. ![]() I would not bother with charging above 30A. Two devices stand above the rest, however. As of July 2019, eMotorWerks is now officially Enel X Way, Enel’s business unit at the vanguard of innovation in energy, sustainability, and digitalization. I think I have educated myself to understand the technical specs of the units, including that the ChargePoint can charge at 48 amp versus the max 40 amp capacity of the ClipperCreek but that requires a hardwire setup and I am leaning toward an outdoor NEMA 14-50 outlet.
