Homeowners want to know whether their 100-amp panel is enough for an EV charger, what the problem is with their Federal Pacific or Zinsco panel, and what a panel upgrade actually involves from permit to inspection. A website that explains amperage requirements and panel hazards earns the upgrade call. Free mockup, no commitment.

Web Design for Electrical Panel Upgrade Companies in Kansas City
Electrical panel upgrade customers are homeowners with a 60 or 100-amp panel in a house adding an EV charger, heat pump, or whole-house generator, homeowners with a Federal Pacific Electric (FPE) Stab-Lok or Zinsco panel that a home inspector flagged as a fire hazard, or homeowners whose panel is full with no available breaker spaces for additional circuits. The central education is amperage capacity and why modern electrical loads have exceeded what 100-amp service was designed to support: a 100-amp service provides 24,000 watts at 240V — a 40-amp EV charger draws 9,600 watts, a 3-ton heat pump draws 3,600 watts at the compressor, and a 10kW whole-house generator transfer switch requires a dedicated circuit — stacking these loads on existing 100-amp service creates capacity shortfalls. 200-amp service: provides 48,000 watts, the current standard for new construction and the minimum recommended for homes with EV charging plus heat pump plus electric appliances. 400-amp service: two 200-amp meters and panels, used for large homes or homes with significant EV fleets; requires utility upgrade at the meter socket. Federal Pacific Stab-Lok panels: manufactured 1950s–1980s; breakers documented to fail to trip on overcurrent — the breaker stays closed when a circuit draws more than rated amperage, allowing the wiring to overheat and ignite insulation. CPSC and independent testing (Schneider Electric study) found significant failure rates. Insurance carriers routinely deny coverage or require replacement. Zinsco/GTE Sylvania panels: similar documented breaker-to-bus bonding failure — breakers can arc when attempting to trip, or fuse to the bus bar and cannot be reset. Permit and inspection: a panel upgrade in Kansas City and Johnson/Jackson counties requires a permit from the local authority having jurisdiction (AHJ) — unpermitted panel work creates insurance and resale problems. The utility (Evergy) coordinates service disconnect for the work day and reconnect after inspection approval. An electrical panel upgrade website that explains the FPE/Zinsco failure mechanisms, what 200-amp vs. 100-amp service actually allows, and what the permit and inspection process involves earns the homeowner who has been putting off the upgrade because they do not understand the risk or the process.
What homeowners research before upgrading an electrical panel
- Amperage requirements — 100A vs. 200A capacity, EV charger + heat pump + generator load calculation
- Federal Pacific hazard — Stab-Lok breaker failure mode, CPSC documentation, insurance implications
- Zinsco hazard — bus bar bonding failure, arc risk, inability to reset, insurer position
- 200A vs. 400A service — when 400A is required, utility meter socket upgrade, two-panel setup
- Permit process — KC AHJ permit requirement, Evergy disconnect/reconnect, inspection approval
What your panel upgrade website would include
- Amperage guide — 100A watt capacity, modern load examples, why EV + heat pump + generator exceeds 100A
- FPE Stab-Lok section — breaker failure mechanism, CPSC documentation, insurer denial risk
- Zinsco section — bus bar bonding failure, arc hazard, insurance implications, replacement urgency
- 200A vs. 400A section — capacity comparison, when 400A is required, utility meter upgrade process
- Permit and inspection section — KC AHJ process, Evergy coordination, why unpermitted work creates problems
- Quote form with panel brand and size, planned new loads, insurance request, full address for permit jurisdiction
What clients say
“Most of my FPE calls started the same way — a home inspector flagged it and the customer wanted to know if it was really a problem or just an inspector being cautious. The website section on the Stab-Lok breaker failure mechanism — actual test data, CPSC documentation, why insurance carriers deny coverage — meant customers arrived already understanding it was a real hazard and not a scare tactic. The permit section also helped: explaining the Evergy disconnect and inspection process upfront reduced the number of customers who were surprised the job takes a full day.”

Simple pricing
A panel upgrade site with amperage guide, FPE/Zinsco hazard section, and quote form starts at $200. A full site with 200A vs. 400A comparison, permit process section, and load calculator is $425–$750. One panel upgrade covers the cost. No contracts, no monthly fees.
