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.
Benefits of 200-Amp Service
A 200-amp panel provides capacity for modern loads with room for future additions.
- Supports EV chargers, hot tubs, additions
- AFCI and GFCI slots reduce fire and shock risk
- Eliminates aging panel corrosion issues
- Improves resale value
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.

- Permits filed by our office
