FAQs
Why should I consider upgrading my electrical panel in Jefferson City?
Upgrading your panel ensures your home meets current NEC and City of Jefferson electrical codes, provides the capacity needed for today’s high-demand appliances and electronics, reduces fire hazards caused by overloaded circuits, and can lower insurance premiums. It’s especially important in homes that still have 60- or 100-amp service, fuse boxes, or panels manufactured by brands with known safety recalls.
How do I know my existing panel is outdated or unsafe?
Common signs include frequent breaker trips, flickering lights, warm breaker handles, a burning smell, visible rust or corrosion, and the presence of fuses instead of breakers. Panels older than 25–30 years or those labeled Federal Pacific, Zinsco, or Challenger should be inspected immediately, as many have documented safety issues.
What size service panel does the average Jefferson City home need today?
Most modern single-family homes require at least 200 amps to safely power HVAC systems, electric water heaters, kitchen appliances, EV chargers, and future solar installations. During an on-site load calculation, a licensed electrician will assess your square footage, major equipment, and planned upgrades to recommend the correct amperage—often 200 A for typical homes and 300–400 A for larger properties or those with multiple EVs.
Do I need a permit for an electrical panel upgrade in Jefferson City?
Yes. The City of Jefferson Building Regulations Division requires a residential electrical permit any time a service upgrade, panel replacement, or meter relocation is performed. A licensed master electrician pulls the permit, schedules inspections, and ensures all work complies with the 2023 National Electrical Code and local amendments.
How long does the panel upgrade process take and will I be without power?
A standard panel replacement typically takes one full day on site. Power is usually shut off for 4–8 hours while the old panel is removed, new service equipment is installed, and the utility reconnects. Complex upgrades or service relocations can extend the outage. Your electrician will coordinate with Ameren Missouri to minimize downtime and advise you on protecting refrigerated goods and sensitive electronics.
What is the cost of an electrical panel upgrade in Jefferson City and are rebates available?
Costs range from $1,800 to $3,500 for a straightforward 200-amp replacement, and $3,500 to $6,500 when the utility service mast, meter base, or main grounding system also needs updating. Adding whole-home surge protection or an EV-ready subpanel increases the price. Ameren Missouri occasionally offers rebates for service capacity increases tied to electric vehicle adoption, and some homeowners qualify for the 30 % federal Residential Clean Energy Credit when upgrading panels to support solar PV.
