Do You Need a 200-Amp Panel for an EV Charger in Riverside, CA?

A 100-amp panel may be enough. The real answer comes from your electrical load, charger size, and future plans, not the number printed on the main breaker.

You do not always need a 200-amp panel for an EV charger in Riverside. Many 100-amp homes can run a 24 to 32-amp Level 2 charger, and load management can make tighter panels work. The real answer comes from a load calculation. Riverside Public Utilities also offers rebates on qualifying permitted installations.

You got an EV charger quote, and the electrician said four words that doubled the price: “You need a panel upgrade.”

Before paying for a 200-amp panel for an EV charger in Riverside, ask to see the load calculation. Some homes need more service capacity. Many do not.

This guide explains how electricians measure capacity, when 100 amps can work, what load management really does, and what Riverside requires. If the numbers point toward replacement, start with our guide to panel upgrades in Riverside.

Can a Level 2 EV Charger Work With a 100-Amp Panel?

The EPA’s home EV charging guidance notes that 100-amp service may be enough depending on the home’s other electrical loads. That matters in Riverside, where housing data places the median construction year at 1976.

A 100-amp service becomes harder to work with when the home already has an electric range, electric dryer, central air, and other large loads. A 48-amp charger may push that system past its calculated capacity.

How Electricians Calculate Your Available Capacity

A licensed electrician should do the math before recommending a larger service. The National Electrical Code provides more than one accepted way to evaluate an existing home.

EV charging is treated as a continuous load, which means the circuit must include a safety margin. Good planning uses the actual charger output rather than assuming every homeowner needs the fastest model available.

What Size Circuit Does a Level 2 Charger Need?

Most drivers can refill their daily mileage overnight without a 48-amp charger. The right EV charger installation balances charging speed with the home’s real capacity.

When Load Management Can Save You a Panel Upgrade

Load management monitors the home’s electrical demand. It slows or pauses charging when other large appliances need power, then resumes charging when capacity becomes available.

Load management should not hide an unsafe or obsolete panel. If the equipment is hot, corroded, full, or a problem model, review the signs of a failing panel before adding another major load.

What Does Riverside Require for an EV Charger or Panel Upgrade?

The City of Riverside upgrade checklist explains the panel process. Franco’s inspections and code compliance service can handle the coordination.

RPU Rebates That Lower the Cost

A permit is not just paperwork when a rebate requires proof of an approved installation. Keep copies of the permit, invoice, charger details, and final inspection.

When Upgrading to 200 Amps Makes Sense

Do not pay for load management on a panel that already needs replacement. Ask about Franco’s 200 amp panel upgrade offer when the long-term plan supports a larger service.
