200A Main Panel Upgrade in Winchester

A 100 amp service upgraded to a new 200 amp main panel, with SCE disconnect and reconnect coordinated by Keen, a Riverside County permit pulled and a final inspection passed. The upgrade that comes before solar, batteries, EV chargers and heat pumps.

Too Little Panel for What Comes Next

Many Inland Empire homes still run on 100 amp service. That is fine until you add an EV charger, a heat pump, a battery or solar, and suddenly there is no room in the panel or the utility will not approve the load.

A panel upgrade means the power is off, the utility has to be scheduled, and the county has to sign off. It needs to be done once and done right.

Scope Delivered

New 200A Main Panel

Removed the old 100A service and installed a new 200A main panel with meter section, recessed into the exterior wall.

Utility Coordination

Scheduled the SCE disconnect and reconnect so the home was back on power the same day.

Permit + Final

Pulled the Riverside County permit and passed the service panel final inspection.

How We Built It Right

Wired for what is next

Breakers are landed neatly with room left for future circuits, so the next project, whether solar, an EV charger or a battery, does not start with another panel job.

What This Project Proves for Your Property

Thinking about solar, a battery or an EV charger on an older home? Start with the panel. Keen's C-10 crews do service upgrades on their own and as part of solar projects, so you get one contractor and one plan.

Questions About Projects Like This

Do I need a panel upgrade for solar or an EV charger? +
Often, if you have 100A service. Solar adds a breaker and a backfeed limit, and EV chargers add significant load. We check your panel and load before recommending an upgrade.
How long is the power off for a panel upgrade? +
Typically most of a day, scheduled with the utility. Keen coordinates the disconnect and reconnect so you are not left managing SCE yourself.
