Electrical Panel Upgrade in Pasadena
If your Pasadena home is running on an outdated 100-amp panel, it’s likely original to a home built decades before central air conditioning was standard. A 200-amp upgrade brings that capacity in line with modern demand, and in Pasadena, that process runs through the city’s own municipal utility rather than a regional provider.
You’re in good hands. Our team will follow up promptly.
Why the Utility Coordination Step Is Different Here
Pasadena is served by Pasadena Water and Power, the city’s own municipally-owned utility, rather than Southern California Edison, which serves most of the surrounding region. That means service disconnects and reconnects for a panel upgrade get coordinated directly with the city, a detail worth knowing if you’ve had utility work done elsewhere before.
With a median home age going back to 1961, and a substantial share of homes older still, the underlying need for an upgrade is often less about a specific project and more about a panel that’s simply reached the end of its useful capacity.
What a Panel Upgrade Includes
- Load calculation to size the new panel correctly for your home
- Coordination with Pasadena Water and Power for the service disconnect and reconnect
- Installing a modern meter-main enclosure with updated weatherhead and riser
- Driven grounding rods and bonded main water line
- Re-routing existing branch circuits into the new panel with modern AFCI protection

FOR HOMEOWNERS
A Recent Pasadena Panel Upgrade
A historic residence operating on an outdated 100-amp panel board needed an upgrade to 200 amps to support a central HVAC installation. We pulled city permits and coordinated with Pasadena Water and Power for a utility disconnect.
The work included installing a 200A meter-main enclosure with an updated weatherhead and riser, driving dual grounding rods and bonding the main copper water line, and re-routing the existing branch circuits into the new panel with modern AFCI protection.
The upgrade passed city building inspection effortlessly, allowing the HVAC installation to proceed on schedule.
If you’re upgrading proactively rather than reacting to a specific problem, an Electrical Safety Inspection in Pasadena is a good way to confirm what else, if anything, needs attention first, particularly given how much older wiring can coexist with a newer panel.
