Many Northern California houses in the (707) area code were built between 1960 and 1999. A lot of these homes have outdated, inefficient, or poorly maintained electrical systems that may require an electrical panel upgrade or breaker box replacement.

An electrical panel is the command center for your home’s electrical system, safely distributing power to lights, outlets, and other electrical devices throughout the house.
If you are experiencing one or more of the following issues, it may be time to upgrade your home electrical panel:
Upgrading or repairing unsafe electrical equipment boosts power capacity to support modern appliances while delivering dependable, long-term performance and peace of mind.

A defective electrical service panel poses a serious fire risk and should be replaced immediately to avoid catastrophic damage. Older homes in Northern California were often equipped with Zinsco electrical panels, which are now severely outdated and known to overheat. Additionally, Federal Pacific Stab-Lok, Sylvania, and Challenger brand panels are recognized fire hazards that should be replaced, as they have lost their UL safety listings.

Modern demands for power often exceed the capabilities of existing systems and require a new electrical panel to ensure better compliance, safety, and reliability.
Fuse boxes, which were commonplace in homes built before 1960, are now considered obsolete and unable to handle modern energy requirements. Circuit breakers provide a much safer alternative, automatically cutting off the current in the case of a short or overcurrent, protecting the home and its occupants from serious harm.
The experienced team at 707 Plumbers, Inc. & Electric has the knowledge and capabilities to assess a home’s electrical system to determine if an electrical panel upgrade is necessary.

During panel replacements, the California Electrical Code mandates the installation of Arc-Fault Circuit Interrupter (AFCI) protection across most residential living areas. AFCI breakers are designed to continuously monitor circuit conditions and detect dangerous electrical arcing.
Additionally, bathrooms, kitchens, garages, basements, laundry rooms, and outdoor spaces require Ground Fault Circuit Interrupter (GFCI) protection. GFCI devices monitor the balance of electrical current between hot and neutral conductors, instantly cutting power in milliseconds if a ground fault or current leakage is detected, effectively preventing severe or fatal electric shocks.
Our licensed electricians understand the current code requirements and can safely upgrade an electrical panel with cost-effective solutions.

At 707 Plumbers, Inc. & Electric, every electrical panel upgrade involves the following process:
