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 Petersham, including the load calculation your panel actually needs.
“Six recessed lights in the kitchen and a dimmer that actually works. The ceiling patch was so small I didn't need a painter.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“They rewired our restaurant kitchen overnight so we never closed a single service. That mattered more than the price, honestly.”

Yes — hardwired, commissioned, and set to the right breaker size for your vehicle and panel.
Most Petersham 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.
