Charging on a standard outlet gets you a handful of miles an hour. A Level 2 charger fills the battery overnight. OSB installs home and workplace EV charging across Wenham, including the load calculation your panel actually needs.
“We had knob-and-tube in the attic and our insurer was getting nervous. They rewired in stages so we never lost power for more than a few hours at a time.”
“Office fit-out on a tight deadline. They worked around our contractor, hit every date, and the inspection passed first time.”
“Six recessed lights in the kitchen and a dimmer that actually works. The ceiling patch was so small I didn't need a painter.”
A short run from a panel with free capacity is often under a thousand dollars plus the unit. Long runs, trenching, or a panel upgrade raise it. We quote flat after a quick look at your panel.

Yes — hardwired, commissioned, and set to the right breaker size for your vehicle and panel.
Most Wenham installs are done in a few hours. Trenching to a detached garage or a same-day panel upgrade extends it to a full day.
We file it, meet the inspector, and hand you the closed permit for any rebate paperwork.
