Electrical Panel Upgrade & Replacement in Liberty, MO
The homes around Liberty's historic square are some of the oldest in the metro, and a good number still have the panel they were built with. If yours is a fuse box, a 60-amp service, or a Federal Pacific, replacing it is one of the highest-value safety upgrades you can make to the house.
What we usually find in Liberty panels
Near the square and around William Jewell, we still open fuse boxes and 60-amp services regularly — enough capacity for a 1940s kitchen and nothing like enough for central air, a second refrigerator, and a car charger. We also find a lot of Federal Pacific Stab-Lok and Zinsco panels from mid-century remodels. Both are widely flagged by electricians and insurers as fire risks because their breakers can fail to trip under load. Newer Kingsridge builds are usually fine on capacity but sometimes full, with no space left for another circuit.


What an electrical panel upgrade costs in Liberty
Most contractors won’t tell you what sets the price until they’re standing in your house. Here’s what we look at, and which parts actually move the number.
| Job | Relative cost | What drives it |
|---|---|---|
| Like-for-like 100A replacement | Baseline | Swapping a failing or unsafe panel without increasing service size. |
| 100A → 200A service upgrade | Higher | New panel, new meter socket, new service entrance conductors. The most common job out here. |
| Fuse box replacement | Highest | Older homes near the square. Often needs mast and grounding work brought up to current code. |
| Sub-panel addition | Lowest | Detached garages, workshops, finished basements. |
The variables that move it most are whether the meter socket and service mast need replacing, whether the grounding electrode system meets current code, and how the utility drop comes in. Flat price before any work starts.
What to Expect
On-site assessment
We open the panel, check the service size, look at the grounding, and count what's actually on each circuit.
Right-sized recommendation
100A, 150A, or 200A based on real load, not a guess. We'll tell you if you don't need the upgrade.
Permit
Pulled through the City of Liberty.
Utility coordination
We schedule the disconnect and reconnect with Evergy so the outage is planned rather than a surprise.
Install and inspection
New panel, labeled circuits, and we meet the inspector ourselves rather than leaving it to you.
Questions We Get in Liberty
How much does it cost to replace an electrical panel in Liberty, MO?
Swapping a failing panel at the same service size is the least involved version. Going from 100A to 200A — the most common job in Liberty — costs more, because it means a new meter socket and new service entrance conductors, not just a new panel. Fuse box replacements near the square run highest, since the mast and grounding usually need bringing up to code at the same time.
How do I know if I need a panel upgrade?
Breakers that trip when two appliances run at once, a fuse box instead of breakers, lights that dim when the AC starts, or a panel with no empty slots left. Adding an EV charger or hot tub is also a common trigger.
Is a Federal Pacific panel really dangerous?
Federal Pacific Stab-Lok and Zinsco panels have a documented history of breakers failing to trip under fault conditions. Many insurers ask about them directly. If you have one, replacing it is the recommendation regardless of whether it's currently causing you trouble.
Will my power be off all day?
Usually four to eight hours, coordinated with Evergy so you know the window in advance. We plan it around your day where we can.
Do you handle the permit and inspection?
Yes. We pull the permit through the City of Liberty and meet the inspector on site.
