200-Amp Electrical Service in Chicago
A 200-amp electrical service delivers 200 amperes of current — double the capacity of a traditional 100-amp service and the de facto standard for modern Chicago homes. It's what we install on nearly every full gut rehab in Lincoln Park, Bucktown, Wicker Park, and Logan Square. It's what builders specify in new construction in West Town and Bronzeville. And it's the upgrade most Chicago homeowners choose when they finally retire a 60- or 100-amp service that can't keep up with central air, induction cooking, an EV in the garage, and a heat pump in the basement.
200-amp service gives a single-family home enough capacity to handle current loads, run multiple large appliances simultaneously, and leave real headroom for future additions — EV chargers, electric water heaters, finished basements, or detached ADUs.
Signs Your Chicago Home Needs 200-Amp Service
Consider upgrading to 200 amps if any of the following applies:
- [EV charger installation](/services/chicago/ev-charger-installation-chicago) (Level 2 chargers pull 32-48 amps continuous)
- Heat pump conversion from a gas furnace or boiler
- In-floor radiant electric heating in a bathroom or basement
- Hot tub or spa installation — see [hot tub and spa electrical](/services/chicago/hot-tub-spa-electrical-chicago)
- [Whole-home standby generator](/services/chicago/generator-installation-chicago) with automatic transfer
- Adding a second dwelling unit — common in Chicago two-flats, three-flats, and coach houses
- Major kitchen or bathroom remodels — see [kitchen electrical remodel](/services/chicago/kitchen-electrical-remodel-chicago)
- Smart home upgrades with many high-demand devices
- Home office expansion with networking gear, servers, and workstation loads
Chicago's older electrical infrastructure, combined with rising demand for electric heating and EV charging, is making 200-amp service the new baseline. If you're doing any significant renovation in an older home, upgrading the service once — and doing it right — is almost always cheaper than returning to the panel twice in five years.
What's Included in a 200-Amp Service Installation
A complete 200-amp service upgrade in a Chicago home covers:
- ComEd service application and scheduled disconnect
- New meter socket rated for 200-amp continuous, per ComEd Book of Standards
- 4/0 aluminum or 2/0 copper service entrance conductor in appropriate conduit
- 200-amp main breaker panel with 40-plus circuit positions
- Whole-home surge protective device at the main — see [whole-home surge protection](/services/chicago/whole-home-surge-protection-chicago)
- Grounding electrode system: two ground rods plus water pipe bond, CSST bond where applicable
- Weatherproof exterior installation rated for Chicago winters
- Permit pulled through the Chicago Department of Buildings
- Final electrical inspection and ComEd release
A 200-amp upgrade in an owner-occupied single-family home typically takes one to two days on-site. For a two-flat or three-flat with metered unit panels, plan on two to three days and additional coordination with ComEd on the metering configuration.
Panel Upgrades vs. Service Upgrades
Homeowners often use "panel upgrade" and "service upgrade" interchangeably, but they're not the same. A panel-only swap replaces the breaker box but keeps the existing 100-amp service, meter, and entrance. A true service upgrade replaces the entire feed — from the ComEd service drop all the way through the main breaker. If your existing service is 60 or 100 amps and you need more capacity, a panel swap alone won't help. You need a full service upgrade to 200 amps.
