New main breaker panel, new grounding and bonding to current code, labeled circuits, meter socket and service entrance work coordinated with the utility, permit and city inspection. Where you want to keep the existing panel we can add a sub panel for a garage, workshop, ADU or EV charger.
Cost depends on amperage, whether the meter and service entrance need replacing, and how the utility feeds the property. We give a fixed written price after a short on-site evaluation. Call (833) 652-8933 to schedule one in Murrieta or nearby Wildomar, Lake Elsinore, Temecula, Menifee.
