Bonsall panel upgrade cost questions
I'm upgrading to 200A for an EV charger. Does that change the price?
Not on its own. The panel upgrade price is the same whether the added capacity goes to an EV charger, a pool, or a kitchen remodel. The charger circuit itself is a separate line item.
Why is North County Inland pricing more predictable than other regions?
Most homes here were built in the same 20-year window with similar wiring and easy garage access, so there are fewer surprises once we open the panel.

For a typical Bonsall rural property (residence plus well-pump plus secondary structures), generator sizing usually lands at 14-22kW.
