What it is
Panel upgrade vs. service upgrade
A panel upgrade replaces the breaker panel, the metal box that holds your breakers. It can keep the same amps or go with a service upgrade.
A service upgrade raises the amps coming into the home. If you need more power, not just more breaker spaces, see 200 amp panel upgrade in Greenville.
- Replacing a worn, damaged or recalled panel
- A larger panel with more breaker spaces
- A subpanel for a shop, garage or addition
- Moving a panel out of a closet or bathroom
Signs the panel needs replacing
- Rust, water marks or scorching inside
- Breakers that will not stay on or feel hot
- Double-tapped or crowded breakers
- An older panel brand with known breaker problems
Getting it done
Permits and GEUS for panel work in Greenville
Panel replacement needs an electrical permit from the City of Greenville. The electrician applies online and books the City inspection.
Changing the main panel usually needs power cut at the meter, so GEUS schedules a disconnect and reconnect. A subpanel fed from the existing panel usually does not.
The electrician labels every circuit in the new panel. Accurate labels help you and any future electrician find circuits fast.
Before you call
- Panel brand and age, if known
- Photo of the panel with the cover on
- What you plan to add
Subpanels
When a subpanel makes sense
A subpanel is a smaller breaker panel fed from the main panel. It adds breaker spaces closer to where you need them.
Subpanels suit shops, garages and additions. They do not add capacity. If the main service is already near its limit, the electrician recommends a service upgrade instead.
Common subpanel spots
- Detached shop or barn
- Garage with tools or an EV charger
- New room addition

Electrical Panel Upgrade in Greenville: FAQs
Talk to a licensed electrician
Describe the problem and your ZIP. We will connect you with a local pro in Greenville.
Call (815) 456-4349What is the difference between a panel upgrade and a 200 amp upgrade?
A panel upgrade replaces the breaker box. A 200 amp upgrade raises the service size and usually replaces the panel, meter base and service wires too.
Does a subpanel give me more power?
No. A subpanel adds breaker spaces. The total power is still limited by your main service size.
Is my old panel unsafe?
Some older panel brands have known breaker problems, and any panel with rust, scorching or hot breakers needs attention. An electrician can inspect it.
