Electrical installation is some of the most consequential work done in a home, and it lasts. A panel or a circuit installed today will carry load for the next 20 to 40 years, so the quality of the work decides how safely the system performs for decades. LBA's licensed electricians install, upgrade, and rewire electrical systems for homeowners across the Kansas City metro, every job permitted, inspected, and built to the National Electrical Code as adopted locally.
Electrical Panel Upgrades in Kansas City & Overland Park
The panel is the distribution center for every circuit in the house, and in much of the Kansas City metro it is undersized for how people live now. A 100-amp panel specified for a 1960s Overland Park ranch was never meant to carry a modern air conditioner, a high-efficiency furnace, an EV charger, a hot tub, and a connected home full of electronics. The result is a panel running at or near capacity, breakers that trip under ordinary load, and no room to add what you actually need.
A 200-amp service upgrade resolves that. It opens capacity for current demand, leaves room for future additions, and is often required before other work can proceed, including an EV charger or a standby generator. LBA performs panel upgrades across the metro and coordinates the service disconnect and reconnect with Evergy as part of the project, so you are not chasing the utility yourself.
Installation Services We Provide
- Panel upgrades and replacements, most commonly from 100-amp to 200-amp service
- Sub-panel installation for additions, finished basements, detached garages, and workshops
- New circuit installation for appliances, additions, and high-draw equipment
- Dedicated circuits for HVAC equipment, electric dryers, ranges, hot tubs, and your water heater
- Whole-home rewiring for older homes with aluminum or knob-and-tube wiring
- Outlet, switch, and lighting rough-in for remodels and new spaces
- Panel-level surge protection installed at the same time as a panel upgrade
New Construction and Older Homes Tell Different Stories
Johnson County communities such as Lenexa, Shawnee, and Olathe have seen some of the metro's fastest residential growth, and newer homes there generally arrive with adequate 200-amp panels. The installation work in those neighborhoods tends to be additive: a circuit for a finished basement, a workshop sub-panel, a charger for a new EV.
Older homes across Kansas City, MO, Mission, and the inner-ring suburbs are a different situation. With a median build year around 1969 and roughly a fifth of Kansas City, MO homes built before 1940, panels rated at 100 amps or less, two-prong ungrounded outlets, and obsolete wiring are common. These are not cosmetic issues. They are capacity and safety limits that affect every appliance and system in the home, and a panel upgrade is often the first step before anything else can be done safely.
Permits, Evergy Coordination, and What to Expect
Most installation work in Kansas City, MO and across Johnson County requires a permit. LBA files the permit applications, coordinates with the local building department, and manages the Evergy service disconnect and reconnect on projects that require it. You do not run that process in parallel with your day job.
Timelines track with scope. A single new circuit is typically a half-day job. A full 200-amp panel upgrade is usually one full day, including utility disconnect in the morning and reconnect in the afternoon, with a stretch of the day without power. Whole-home rewiring is scoped individually. Larger projects can be paired with financing.
Frequently Asked Questions
Panel upgrade cost depends on the existing service configuration, permit fees, the Evergy coordination required, and the specific panel and breakers installed. LBA provides upfront pricing after an assessment of what your existing system actually needs. We do not quote a number before we understand the panel we are replacing.
Most residential 200-amp upgrades are completed in one day. The day usually includes an Evergy disconnect in the morning, the panel swap, and reconnect in the afternoon, so plan for a portion of the day without power. LBA schedules the utility coordination for you.
Yes, for most installation work. Kansas City, MO and Johnson County both require permits for panel upgrades, new circuits, and EV charger installs, and the permit must be in place before work begins. LBA handles the application and the inspection. Unpermitted work can affect your insurance and create a problem at resale.
Most metro homes are well served by 200-amp service. Homes with an EV, electric heat, a hot tub, a large workshop, or plans to expand may need a 200-amp panel plus a sub-panel, or in some cases 400-amp service. The right answer comes from a load calculation, which we perform before recommending anything.
Sometimes. A 200-amp panel with open breaker space can usually take a 30 to 50-amp EV circuit without an upgrade. A 100-amp panel running near capacity likely needs an upgrade first. We evaluate this upfront. See the EV charger installation page for detail.
Yes. Whole-home rewiring for older homes in Kansas City, MO, Mission, and the inner-ring suburbs is part of what we do, including homes with aluminum branch wiring or knob-and-tube. These projects are scoped individually based on construction and existing wiring. Call (913) 268-6822 or visit the electrical hub to start.
