Electrical Panel Upgrade

Upgrade your panel from 100 to 200 amps — permits, utility coordination, and fixed pricing by licensed electricians.

An electrical panel upgrade — also called a service upgrade — increases the amperage capacity of your electrical service to support modern household loads. Most homes built before 1990 were equipped with 100-amp panels. Today’s standard is 200 amps, and homeowners adding EV chargers, hot tubs, or additions often find 100-amp service cannot safely accommodate the load. Our licensed electricians handle the full process: load calculation, panel replacement, utility meter pull coordination, permit filing, and final inspection. We provide a fixed quote before any work begins, and every upgrade is documented with a passed inspection record for your insurance and resale files.

Electrical Panel Upgrade — Everything You Need to Know

From timeline and permit requirements to signs your panel is failing — here’s what homeowners need to know about panel upgrades before requesting service.

What a Panel Upgrade Involves

A panel upgrade begins with a load calculation confirming the correct target amperage. We assess the existing panel, service entrance conductors, and meter base to identify what needs replacing alongside the main panel. On installation day, we coordinate with your utility to pull the meter, de-energize the service, and restore power after installation. Circuits are transferred, connections torqued to specification, and breakers labeled. Depending on the utility, the upgrade may also require replacing service entrance cable or the weatherhead. Most residential upgrades complete in a single day.

Signs You Need a Panel Upgrade

Planning to add an EV charger, hot tub, or home addition is the most common trigger — a load calculation often reveals insufficient headroom even when the panel appears functional. Other indicators: panel older than 25 years, Federal Pacific Stab-Lok or Zinsco equipment regardless of age, split-bus panel without a single main breaker, breakers tripping under normal loads, and insurance carriers flagging the panel as a condition of coverage renewal.

Why Our Upgrades Stand Out

Permit filing and utility coordination are included in our quoted price. We work with LADWP, SCE, PG&E, and Pasadena Water and Power on meter pulls and service restorations. Every upgrade uses materials meeting or exceeding code, and we schedule the job to minimize time without power.

  • Fixed quote before work begins
  • Permits filed by our office
  • Utility coordination handled
  • Inspection record provided
  • Same-day available

Re-Entry Safety Advisory

Before You Return to a Flooded Property

Has your property been evacuated or marked unsafe? Wait until civil authorities officially allow entry. Receding water does not automatically mean a building is safe to enter.

Immediate Danger: Leave the area immediately and call 911 if you encounter active sparking, structural instability, or immediate hazards.
Property Access & Electrical Inspection Protocol
⚠️ Flood-Exposed Systems: Our electricians recommend having all flood-exposed wiring, service panels, and outlets evaluated before any circuits are energized or used again.
✓ Requesting Service: Once official entry access is permitted, call with your address and a description of what areas were affected by water.
✓ Future Preparation: For future weather events, a safety inspection can identify existing electrical concerns while the property is completely dry and safe.
We hope you and your loved ones are somewhere safe.
