For common sizes, a 32A charger uses a 40A breaker, 40A → 50A, 48A → 60A, 80A → 100A; commercial 70A needs a 90A breaker. Use a dedicated 240V circuit; wire gauge must match the 125% sizing for code compliance. Remember plug-in options are usually ≤50A; larger breakers require. . WARNING: This manual contains important instructions for installing and using the Watti Home Gen2 EV charger. This is necessary because a 60 Amp dedicated circuit breaker is required for the installation, and the National Electrical Code (NEC) mandates that electrical circuits be rated for at least 25% more amperage. . I have my electrical panel in my drywalled garage, and want to install a 48A EV charger on the wall next to the panel. My plan was to run wire through the bottom of the panel, sideways through one stud, and then up the drywall space into the back of the EV charger. Do not remove cover or attempt to open the enclosure of the device.
