We've upgraded hundreds of panels throughout California — from 60A and 100A panels in older homes to 400A commercial service upgrades for growing businesses. Every upgrade is performed to current California electrical code, with all permits pulled and inspections coordinated on your behalf.

Panel Upgrade Questions
Common questions from California homeowners and business owners about electrical panel upgrades.
How do I know if I need a panel upgrade?
Signs you need a panel upgrade include: breakers that trip frequently, lights that flicker or dim when appliances turn on, a panel rated under 200A, a home built before 1990, Federal Pacific or Zinsco brand panels, plans to install an EV charger, adding a major appliance, or building an ADU. We offer free assessments to give you a definitive answer.
How much does an electrical panel upgrade cost in California?
Panel upgrade costs vary based on the upgrade size, your property's existing wiring, utility requirements, and local permit fees. We provide free, itemized estimates with no hidden fees — so you know the exact cost before we start. Contact us for a quote specific to your property.
How long does a panel upgrade take?
Most residential panel upgrades are completed in 4–8 hours, meaning your power is off for only part of one day. Larger upgrades or those requiring significant utility work may take longer. We give you a clear timeline during your estimate so you can plan accordingly.
Do I need to be home during the panel upgrade?
We recommend being home or having a representative present for the start and end of the job. During the work itself, you're welcome to go about your day. We'll communicate clearly about when power will be off and when it will be restored.
Will a panel upgrade affect my homeowner's insurance?
Yes — positively. Upgrading from an outdated or recalled panel (Federal Pacific, Zinsco, fuse boxes) to a modern code-compliant panel can lower your insurance premiums and prevent your insurer from dropping coverage. We provide full documentation of the completed upgrade for your insurance provider.
