Why upgrade your electrical panel?

Your panel decides how much power your home can safely use. Many Riverside-area homes still run on 100 or 125 amp panels built for a time before central AC, EV chargers and induction ranges. When you ask too much of an old panel, breakers trip, wires run hot and adding anything new becomes a problem.

A panel upgrade gives your home the capacity it needs today and room for what you add next, whether that's an EV charger, a heat pump, solar or a Generac standby generator.

Signs you need a panel upgrade

  • Breakers trip when the AC, dryer or microwave runs
  • You're adding an EV charger, heat pump, spa or new AC
  • Your home still has a 100 amp panel or a fuse box
  • Lights dim or flicker when big appliances start
  • The panel is warm, buzzing, rusty or shows scorch marks
  • Your panel is a brand insurers and inspectors flag, like Zinsco or Federal Pacific
  • You're planning solar, batteries or a standby generator
  • A home inspection called out the panel

What's included

  • Load calculation so the new panel is sized right
  • Permit pulled with your city
  • Coordination with SCE for the disconnect and reconnect
  • New main panel, breakers and labeling
  • Grounding and bonding brought up to code
  • City inspection scheduled and met on site
  • Power restored the same day whenever possible
  • Clean-up and a walkthrough of your new panel

FAQ

Panel upgrades: common questions

How much does a panel upgrade cost?

It depends on your current panel, the size of the upgrade, whether the meter or service wires need replacing, and what your city requires. We give you a clear, written price after a free on-site estimate.

How long will my power be off?

For most homes the power is off for one working day while the old panel is swapped. SCE schedules the disconnect and reconnect, and we plan the work around it.

Do I need 200 amps?

If you're adding an EV charger, heat pump, new AC, spa or solar, 200 amps is the usual target. We do a load calculation to confirm what your home actually needs.

Can the SCE Charge Ready program pay for my upgrade?

Eligible SCE customers may get up to $4,200 toward a panel upgrade and EV charging circuit through the Charge Ready Home Program. Check our Charge Ready page to see if you qualify.

Do you upgrade commercial panels too?

Yes. We handle commercial service upgrades and subpanels, with shutdowns planned around your business hours.
