Electrical Panel Upgrades for EV Charging in San Mateo

More capacity for older Peninsula homes, from mid-century ranches near Alameda de las Pulgas to bungalows in North Central.

When the Panel Says No

Plenty of San Mateo homes were built long before anyone planned for a car that charges in the garage. Many still run on 100A service, and their panels are already carrying ranges, dryers, heat pumps or a remodel's worth of new circuits. Adding a 40A or 60A charger to that can mean nuisance trips or worse. San Mateo EV Charger Installation starts with a real load calculation. If the panel can handle the charger, we tell you. If it cannot, we lay out the options, from load management to a full 200A service upgrade, and coordinate the work with PG&E.

What a Panel Upgrade Covers

A service upgrade touches the meter, the panel and the utility. We handle all of it.

  • Load calculation

    We calculate your home's demand under code rules to see exactly how much capacity is free, and what a charger would add.

  • Load management options

    Before recommending an upgrade, we look at smart chargers, load-sharing devices and circuit pausing that can avoid one.

  • 100A to 200A service upgrade

    New panel, new meter base where required and properly sized service conductors.

  • PG&E coordination

    We submit the service request and schedule the disconnect and reconnect with PG&E.

  • Breaker replacement and cleanup

    We replace outdated or mismatched breakers and fix double-tapped or overloaded circuits we find along the way.

  • Grounding and bonding to current code

    We bring the grounding electrode system and bonding up to current code as part of the upgrade.

  • Labeled circuit directory

    Every breaker gets a clear label so you know exactly what is what.

  • Charger circuit included

    When the upgrade is for an EV, we add the charger circuit in the same project.

  • Permit and inspection

    We pull the permit and handle the inspection for the service change and the new circuit.

How a Panel Upgrade Works

Assessment

Call (650) 727-5460 and send a photo of your panel and meter. We run the load calculation and tell you whether you need an upgrade or a smarter, cheaper workaround. You get the options in writing with prices.

Utility scheduling and permit

We file the permit and submit the PG&E request. PG&E sets the disconnect date. We keep you posted by text so you know when power will be off.

Upgrade day and inspection

On upgrade day, power is typically off for most of the working day while we swap the equipment. We restore power, test every circuit, then meet the inspector to close the permit.

Why Trust Us With Your Panel

We try to avoid the upgrade first

A service upgrade is a big job. If load management gets you charging safely, we recommend it. You get both options and the numbers behind them.

We handle PG&E

Utility coordination is where panel projects stall. We submit, follow up and schedule so you do not have to.

Clean, labeled, documented

Every circuit labeled, every connection torqued, every permit finalled. Your panel will be easier to work on for decades.
