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 Barnstable, including the load calculation your panel actually needs.
“Every smart switch I bought failed because there was no neutral. They pulled neutrals in the rooms that needed it and set up the rest properly.”
“Lost a furnace board and a TV in one storm. They put a surge device on the panel and explained exactly what it does and doesn't cover.”
“Office fit-out on a tight deadline. They worked around our contractor, hit every date, and the inspection passed first time.”

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