Signs You Need an Electrical Panel Upgrade
Frequent breaker trips or lights that flicker when your refrigerator or other major appliances turn on often indicate that your existing panel is undersized for the electrical load your household now demands. Homes that still rely on outdated fuse-based systems face similar capacity constraints. Legacy panel brands such as Federal Pacific Stab-Lok and Zinsco are another serious concern, as industry documentation shows they may fail to trip during overloads. If you notice any of these signs, having a licensed and insured electrician perform an assessment is the surest way to determine whether an upgrade is necessary. Once one or more warning signs are present, understanding the practical upgrade process becomes the logical next step.
How an Electrical Panel Upgrade Works in Altadena
After identifying your signs for an upgrade, we go over what to expect when upgrading your electric service panel in Altadena. First, we do a load calculation to determine if your 60- or 100-amp service needs to be upgraded to 200-amps. We pull the permits with LA County Public Works for unincorporated Altadena. We coordinate with SCE or PWP for both disconnect and reconnect. Surge protection is required on all new services, so we install a whole home surge protection device. We evaluate any Federal Pacific and Zinsco panels for safety and replace if necessary. Disconnect the power, remove the old panel, install the new breakers and surge protector, and connect the new panel and test. Call in the final inspection to ensure our work is up to code.
24/7 emergency electrician services keep you covered during the entire process.
Choosing Your Panel Upgrade: Amperage, Brands, and Permits
When considering an electrical panel upgrade in Southern California, it is essential to find a balance between current needs of your household and the demands of the future. When increasing the amperage from the existing service of 60-100 amps, it’s usual for homeowners to increase the service to 200 amps. New single-family homes in California, per Title 24, require a 200-amp service. Federal Pacific and Zinsco panels have documented reliability concerns and should be evaluated for replacement. Permits in unincorporated Altadena are handled through LA County Public Works. Upgrades require a whole-house surge protective device. California code requires a 36-inch clear working space in front of the panel, 6 feet 6 inches of vertical clearance, and prohibits panels in bathrooms, closets, or above stairways. Coordinate with Southern California Edison or Pasadena Water and Power. With the service size and type decided, next consider how your Altadena location might impact the installation.
Altadena and Foothill Area Considerations for Panel Upgrades
When upgrading electrical panels in the Altadena area, any project must account for local permitting through LA County Public Works, particularly for unincorporated communities. We evaluate the safety of older models, such as Federal Pacific and Zinsco, due to reliability concerns. With high-draw appliances such as EV chargers and induction ranges, a 200-amp service is often required, and we perform precise load calculations to determine when a full upgrade is necessary. Current code mandates that a surge protector be installed on the service to the home for all new dwelling service replacements, safeguarding electronics across the foothill communities.
Our team serves Altadena and surrounding foothill communities including Pasadena, Sierra Madre, and La Cañada Flintridge, and our location at 2408 Lincoln Ave in Altadena means we’re intimately familiar with local terrain and regulations.

Factors Affecting Electrical Panel Upgrade Costs
There are a number of costs associated with an electrical panel upgrade. Each of these will be evaluated on a case-by-case basis for Altadena and the foothill communities.
- Service capacity upgrades from 100A to 200A require heavier wiring and formal load calculations.
- Legacy panels such as Federal Pacific and Zinsco typically need complete replacement, not repair.
- Mandatory whole-home surge protection adds a required component to new service installations.
- LA County plan review and inspection fees contribute to overall project scope.
- Routing wiring through existing construction and resolving hidden deficiencies affect labor time, making a site visit essential.
Keep in mind the factors that affect time also affect cost. The information we provide allows homeowners a general idea of the process.

Frequently Asked Questions
Is a 100 amp panel up to code?
For new single-family homes in California, a 100-amp panel is not up to code because the California Electrical Code mandates a minimum 200-amp service. For existing homes, a 100-amp panel may be allowed if it adequately handles the current electrical load, but an upgrade is often necessary for modern high-draw appliances.
How much clearance do you need from an electrical panel?
The required clear working space in front of an electrical panel is 36 inches deep, with a width of at least 30 inches or the equipment width, whichever is greater. Vertical clearance must be at least 6 feet 6 inches from the floor. Panels are prohibited in bathrooms, closets, and above stairways.
