Electrical Panel Upgrade

We assess your existing service, panel condition, available breaker space, and planned electrical loads before recommending a panel replacement or service upgrade. Permit and utility coordination depend on the project and local jurisdiction.

Plan the Panel Around the Loads You Actually Need

A larger panel is not automatically the right answer. We first separate equipment condition, available breaker space, and calculated electrical demand so the proposed work fits your home and future plans.

Condition and Compatibility

We identify the existing panel, main breaker, meter arrangement, grounding, and any equipment compatibility concerns.

Capacity Review

A load calculation, the worksheet used to estimate the home's electrical demand, checks whether planned loads can be added safely.

Permit and Utility Scope

A panel replacement, service upgrade, or relocation can involve different city and utility steps. We define those steps before scheduling.

Clear Circuit Directory

The completed panel should have an accurate circuit directory so future service work starts with useful information.

Plan the panel around present and future loads

Breaker space, panel condition, service capacity, and calculated demand are separate checks. A load calculation is the worksheet used to estimate the home's electrical demand. Identify planned equipment before selecting a panel scope.

Does an open breaker space prove capacity is available?

No. An open space shows physical room for a breaker, while a load calculation evaluates electrical demand.

What information helps with the first review?

Provide clear panel photos, the main-breaker rating, planned equipment, and any known utility or permit records.

What We Do

Panel Upgrade Services

We assess panel condition, service capacity, permit requirements, and any PG&E involvement before defining the work.

100A → 200A Upgrades

A service-capacity increase may support new electric vehicle charging, induction cooking, heat-pump equipment, or other loads. The required panel, meter, and utility work depends on the existing service and calculated demand.

Federal Pacific Replacement

Federal Pacific Stab-Lok equipment has documented breaker-performance concerns. We confirm the equipment and assess its condition before recommending replacement.

Zinsco / Sylvania Replacement

We identify Zinsco or Sylvania equipment and assess its condition, listing compatibility, and connection to the existing service. Replacement equipment is selected for the project-specific service, listing, and permit requirements.

Sub-Panel Installation

A subpanel, a secondary distribution panel supplied from the main panel, can add circuit spaces near new loads. Available service capacity must still be checked.

Fuse Box Replacement

We assess the fuse equipment, connected circuits, service, and grounding before defining a replacement scope.

EV-Ready Panel Prep

We can include known future loads in the capacity review. Each later installation still needs equipment-specific design and approval.

PG&E Coordination

We define the applicable city and PG&E steps after confirming the jurisdiction and approved scope.

Reconnection Planning

The outage and reconnection schedule depends on the installation, inspection, and utility sequence. We review the expected timing before work begins.

When to Upgrade

Signs You Need a New Panel

Breakers trip frequently

Frequent tripping can have several causes, including an overloaded circuit or a fault. An inspection is needed before assigning the cause to the panel.

You see scorch marks or buzzing

Scorching, heat, odor, or buzzing warrants prompt professional inspection. The inspection determines whether repair, equipment replacement, or another response is appropriate.

No room for new circuits

A full panel may need a compatible expansion option, load review, or replacement. Available breaker spaces alone do not establish service capacity.

Federal Pacific / Zinsco label

Insurance requirements vary by carrier and policy. Confirm any coverage condition directly with your insurer.

Fuse box still in use

Fuse equipment should be assessed for condition, capacity, grounding, and the planned loads. Any lender or insurer requirement should be confirmed directly with that organization.

Planning for a sale

Before a sale, an electrical assessment can document panel condition and identify work that may affect the transaction. Cost recovery and buyer response cannot be assumed.

How It Works

Our Panel-Upgrade Process

Site Assessment

We inspect the panel, meter location, grounding, available breaker space, and the equipment you plan to add. A load calculation, the worksheet used to estimate a home's electrical demand, may be needed before we recommend a scope.

Permit and Utility Review

The approved scope identifies the permit and utility steps that apply. Fox Electric coordinates the applicable steps, but owner participation or direct utility action may also be required.

Scheduled Installation

We replace the approved equipment, complete the specified grounding work, label the circuits, and coordinate reconnection when utility work is part of the project. The schedule depends on the permit, utility, access, and scope.

Inspection and Closeout

We coordinate required inspections and provide the available project closeout and product documents.

Planning Example

Planning Example: Older Panel Replacement

Planning example: replacing older panel equipment begins with positive identification of the panel, an assessment of the existing service and grounding, and a review of planned electrical loads. The final equipment and permit scope follow from those findings.

Existing equipment: Confirm the manufacturer, model, rating, and condition
Capacity: Review electrical demand and planned future loads
Approvals: Identify city and utility steps before scheduling
Final scope: Select equipment after the assessment and load review

The Fox Difference

Why Choose Fox for Your Panel Upgrade

Outage Planning

We plan the outage around the approved scope, inspection, and utility requirements, then explain the expected sequence before work begins.

PG&E Coordination

We identify and coordinate the utility steps required for the approved project. The property owner may need to provide information or respond to utility requests.

Permit and Inspection Scope

When permitting applies, we include the required application and inspection steps in the project scope and retain the available closeout records.

Future Load Planning

We review planned electric vehicle charging, heat-pump, induction, and other loads before selecting panel capacity. Future equipment still requires its own specifications and installation review.

Older Equipment Assessment

We identify Federal Pacific and Zinsco equipment, assess its condition, and explain the replacement options that fit the existing service.

Circuit Directory

We prepare a clear circuit directory based on the circuits identified during the approved work.

FAQ

Panel Upgrade Questions

How long does a panel upgrade actually take?

The installation schedule depends on the panel location, approved scope, permit, inspection, and any utility work. We explain the expected outage and sequence after those details are confirmed.

What affects the cost of a panel replacement or service upgrade?

Cost depends on whether the project is a panel replacement, service-capacity increase, relocation, or a combination of these. Access, utility requirements, grounding work, and the selected equipment also affect the scope.

Will my power be off all day?

The outage window depends on the approved scope, inspection sequence, and utility schedule. We explain what must be turned off and when power is expected to return after those details are confirmed.

Do you handle the PG&E paperwork?

When utility coordination is required, we identify the application and project information needed for the approved scope. Some utility decisions and communications may still require the property owner's participation.

My panel is Federal Pacific. Is it really dangerous?

Federal Pacific Stab-Lok equipment warrants a careful assessment because documented breaker-performance concerns may affect the replacement decision. We confirm the equipment and condition before recommending a scope.

Will an upgrade require permits?

Permit requirements depend on the work and jurisdiction. When a permit is required, the project scope identifies the application, inspection, and closeout steps.

What's the warranty on a panel upgrade?

Any workmanship terms and manufacturer coverage will be stated in the project documents and applicable product materials.
