DETACHED GARAGE INSTALLATIONS
The existing wiring to most detached garages is adequate for general lighting and 120-volt outlets. Powering up an EV needs quite a bit more power than this. When a detached garage has no power or only basic 120-volt power, we usually install a 100-amp feed underground or overhead to the garage. A sub-panel is then installed in the garage, which will feed the charger and re-feed the existing general lights and receptacles. These installations generally require a site visit to determine whether an underground or overhead method is best for the field conditions.
