Electrical panel upgrades built for what comes next.
If breakers trip, the panel is obsolete, or the home needs more capacity for an EV, AC, heat pump, addition, or workshop, we plan the whole upgrade path.
A panel upgrade is a service project, not a box swap
Capacity, service conductors, grounding, meter equipment, utility requirements, placement, and connected loads all belong in the plan.
- ✓Existing service size and condition
- ✓Utility and meter requirements
- ✓Grounding and bonding
- ✓Current and planned electrical loads
