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 Wellesley, including the load calculation your panel actually needs.
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
