Electrical Panel Upgrades in Chicago & DuPage County
Upgrade your electrical panel for generators, EV chargers, or modern electrical demand — licensed, permitted, and installed by the same team that sizes and sells the equipment.
What's Included in a Standard Panel Upgrade
- Site evaluation and load calculation to confirm correct panel size
- Removal of the existing panel and installation of the new panel (typically 100A to 200A, or 200A to 400A)
- Breaker replacement and circuit re-termination to code
- Grounding and bonding brought up to current electrical code
- Municipal permitting and inspection coordination
- Final testing and homeowner or facilities walkthrough
Mr. Volt Inc. upgrades electrical panels for homeowners and businesses throughout Chicago, Willow Springs, and the greater Chicagoland area. Panel upgrades are often required before adding a generator, EV charger, or additional circuits — because we handle generator and EV installs too, your panel is sized correctly the first time instead of being upgraded twice.
Common Panel Sizes
| Panel Size | Typical Use Case |
|---|---|
| 100A | Older homes with light electrical load; often needs upgrading before adding major appliances |
| 200A | Most common upgrade target — supports generators, EV chargers, and modern home electrical demand |
| 400A | Larger homes, homes with multiple high-draw systems, or commercial / light industrial properties |
Chicago-Area Permitting
Panel upgrades in Chicago and most collar suburbs require an electrical permit and inspection before the new panel can be energized. We handle permit submission and inspection scheduling as part of the upgrade so you're not tracking down inspectors yourself.
Common Questions
How do I know if I need a panel upgrade?
If you're adding a generator, EV charger, or additional major appliances and your panel is 100A or older, it likely needs an upgrade. A site evaluation and load calculation will confirm exactly what's needed.
How long does a panel upgrade take?
Most residential panel upgrades are completed in a single day once permits are in place. Commercial jobs are scoped individually based on panel size and site conditions.
Will I lose power during the upgrade?
Yes, power is shut off for the duration of the panel swap, typically a few hours. We coordinate timing with you in advance.
What's the service area?
