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 Holden, 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.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”

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

We file it, meet the inspector, and hand you the closed permit for any rebate paperwork.
