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 Harwich, including the load calculation your panel actually needs.
“They found a loose neutral that had been slowly cooking our appliances for years. Nobody else even looked for it.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
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 Harwich 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.
