Electrical Panel Upgrades for EV Charging in Westminster, CA
When the service cannot carry a charger circuit, the panel is the job. We upgrade 100-amp services to 200 amps, coordinate with the utility, and clear the way for charging that will not trip.

When a Panel Upgrade Is the Real Answer
A lot of Westminster housing stock still runs the original 100-amp service, and by the time you add central air, an electric dryer, and a range, there is little headroom left for a 48-amp continuous load. A load calculation tells you whether that is your situation. If it is, upgrading to 200 amps is not just about the charger — it removes the ceiling on everything else you might add later.
What the Upgrade Covers
A documented load calculation
Performed to the NEC standard, showing exactly what your current service supports and what it will support afterward.
New panel, main breaker, and grounding
Modern panel with proper bonding and grounding electrode conductors, which many older installations lack entirely.
Utility coordination
We file with the utility, schedule the disconnect and reconnect, and align it with the city inspection so your power is off for hours, not days.
The charger circuit landed and tested
The upgrade and your EV circuit are one project with one price, not two separate jobs.
Old Panels, New Cars
Insufficient service is the single most common reason a Westminster EV charger quote goes up. Finding it early is much cheaper than finding it after a charger has been mounted. It is also the reason we do the load calculation before quoting rather than after.
How the Job Runs
- 01
Site visit and load calculation
Panel work is one of the few jobs we always look at in person before quoting.
- 02
Flat quote and utility filing
Fixed price in writing, then we file with the utility and the city.
- 03
Disconnect, upgrade, reconnect
Coordinated so your power is out for hours in a single working day, not across days.
- 04
Charger circuit and sign-off
Your EV circuit is landed on the new panel, then we meet the inspector and close the permit.
Panel Upgrade Questions
Do I definitely need 200 amps?
Not always. Load management devices can sometimes let a charger share existing capacity safely. We price both routes when both are viable.
How long will my power be out?
Typically most of one working day, coordinated with the utility so it happens in a single window.
Does a panel upgrade qualify for rebates?
Sometimes, when it is done as part of an EV charging project. We document it so the claim is possible.
Will you also replace old wiring?
We flag anything unsafe we find, but the upgrade itself covers the service and panel. Any additional work is quoted separately and only with your approval.
