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 Marblehead, including the load calculation your panel actually needs.
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“Whole-house LED retrofit across our warehouse. Our lighting bill dropped and you can finally read labels on the top rack.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
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 Marblehead 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.
