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 Ayer, including the load calculation your panel actually needs.
“Breaker had been tripping for months and two other companies just replaced parts. OSB traced it to a backstabbed outlet behind a bookcase in twenty minutes.”
“They found a loose neutral that had been slowly cooking our appliances for years. Nobody else even looked for it.”
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
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.
Not always. A load calculation decides it. Many Ayer homes on 200 amp service take a 48A charger without changes; older 100 amp services often need an upgrade or a load-management device.
Yes — hardwired, commissioned, and set to the right breaker size for your vehicle and panel.
Most Ayer 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.
