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 Otis, 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.”
“Our panel was original to the house and completely full. OSB upgraded us to 200 amp, pulled the permit, met the inspector, and left the basement cleaner than they found it.”
“Fan on a vaulted ceiling that two handymen said couldn't be done. Right downrod, right box, level and silent.”
