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 North Chatham, including the load calculation your panel actually needs.
“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.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”

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