Start With the Right Recommendation
Does Your Home Need a New Electrical Panel?
Not every older electrical panel needs immediate replacement, and not every new appliance requires an electrical service increase.
The important questions are whether your equipment is in suitable condition, whether your service can support the electrical demand, and whether the installation meets applicable requirements.

Recognizing the Warning Signs
Three Reasons to Have Your Electrical Panel Evaluated
These are common situations that bring homeowners to Dollens Electric for a professional assessment.
Electrical Safety Concerns
Breakers that repeatedly trip, damaged equipment, overheating, corrosion, buzzing, burning odors or other unusual electrical symptoms.
Aging or Limited Equipment
Deteriorated panels, older service configurations, limited breaker space, or equipment identified during a home or insurance inspection.
Upcoming Home Improvements
EV charging, heat pumps, battery storage, electric appliances, additions or remodeling that may change your electrical requirements.
Not Sure Whether You Need a Replacement or an Upgrade?
You don't need to know your existing amperage or select equipment before contacting us. Explain the concern or planned improvement, and we'll help determine what type of evaluation is appropriate.
Electrical Service Capacity
200-Amp or 400-Amp Service?
A 200-amp service is common in modern single-family homes. Larger homes or properties with substantial electrical demand may require higher-capacity configurations.
The appropriate size depends on calculated loads, the existing installation and applicable utility requirements.
We recommend capacity based on the home, not simply the largest available panel.

Understanding Your Investment
How Much Does an Electrical Panel Upgrade Cost in San Jose?
There is no single price that accurately represents every panel upgrade. The scope of work determines the estimate.

Replacing existing equipment can be substantially different from increasing utility service capacity.
Installation Conditions
Equipment location, accessibility, required corrections and service configuration affect the work.
Utility & Project Complexity

Questions Homeowners Ask
Main Electrical Panel Upgrade FAQs
How long does a main electrical panel upgrade take?
Some straightforward panel replacements can be completed in one working day. The overall timeline depends on the installation, permitting, inspections and utility scheduling.
Will my power be turned off during the upgrade?
Yes. Replacing main electrical service equipment requires a temporary outage. The duration and restoration arrangements depend on the work and utility coordination.
Do I need a 200-amp panel to install an EV charger?
Not necessarily. Existing demand, charger requirements and available load-management options determine whether a service upgrade is needed.
When is 400-amp service appropriate?
Higher-capacity service may be appropriate for homes with substantial electrical demand or expansion plans. The decision depends on load calculations and utility requirements.
Is a permit required for a panel upgrade in San Jose?
Yes. Main electrical service upgrades require applicable electrical permits and inspection. The precise requirements depend on the work.
Does PG&E need to approve my panel upgrade?
PG&E involvement depends on the proposed service changes, meter configuration and utility requirements. Service modifications commonly require utility coordination.
Should Zinsco or Federal Pacific panels be replaced?
These legacy panel types have recognized safety and reliability concerns. A licensed electrician should evaluate the equipment and recommend appropriate corrective work.
Can an upgrade accommodate solar or battery backup?
Yes. Solar interconnection and battery backup requirements can be considered when planning the electrical service configuration.
