Electrical Panel Upgrade in Nampa, ID
As the Treasure Valley has boomed, many Nampa owners of older homes north of downtown and mid-century houses near Lakeview Park have found that their 60 or 100 amp services cannot carry central air, a heat pump, a hot tub or an EV charger. Homes on larger lots often add shops and outbuildings, which need a subpanel and a feeder sized for welders, compressors and heaters.
