Panel Replacement Expertise
Modern Commercial Panel Distribution
Commercial electrical panels are the central nervous system of your building’s power distribution. When panels age, become overloaded, or fail to meet current code requirements, they create safety hazards, limit your operational capacity, and risk expensive equipment damage from voltage irregularities. Moonlight Electric Solutions specializes in commercial panel replacement throughout Cheyenne and southeastern Wyoming, delivering modern distribution equipment with minimal disruption to your business operations.
Many commercial buildings in Cheyenne still operate with original panels installed during construction decades ago. These panels may use obsolete breaker types that are no longer manufactured, lack sufficient circuit space for modern loads, or contain components that have degraded from years of thermal cycling and environmental exposure. Federal Pacific, Zinsco, and certain early Pushmatic panels have well-documented safety issues that warrant immediate replacement regardless of apparent functionality.
Isaac Garcia’s experience with power distribution systems in high-reliability environments means our commercial panel replacements follow a meticulous process. Every wire is labeled, every circuit is documented, and every connection is torqued to manufacturer specifications. The result is a clean, well-organized panel that passes inspection the first time and provides reliable power distribution for decades to come.
A commercial panel replacement is not just swapping hardware. It is an opportunity to right-size your distribution, correct code violations, and organize your electrical system for clear, maintainable operation.
Commercial panel replacements differ significantly from residential panel swaps in both complexity and coordination requirements. Commercial panels often serve multiple tenants, critical equipment, and life-safety systems that require careful sequencing during the changeover. Our planning process identifies every load connected to the existing panel, determines the correct replacement panel configuration, and develops a power transfer sequence that minimizes outage duration and protects sensitive equipment.
We replace all types of commercial panels including single-phase and three-phase panel boards, main lug and main breaker configurations, and capacities from 100 amps through 800 amps. For buildings requiring more than 800 amps, we install distribution switchboards and coordinate with your utility for any required service-side modifications. Every replacement panel includes a complete circuit directory, proper breaker coordination, and adequate space for future circuit additions.

Commercial Panel Replacement Capabilities
Three-Phase Panel Replacement
Replacement of three-phase 208V and 480V commercial panel boards. We match replacement panels to your existing configuration or upgrade to higher-capacity equipment. All three-phase connections are verified for proper phase rotation and balanced loading.
Single-Phase Commercial Panels
Replacement of 120/240V single-phase commercial panels including main breaker panels, main lug panels, and sub-panels. We size replacement panels with additional circuit space to accommodate future growth without requiring another panel replacement.
Hazardous Panel Replacement
Priority replacement of Federal Pacific, Zinsco, Pushmatic, and other panels with documented safety deficiencies. These panels have failure modes that create fire and shock hazards. We provide same-week emergency replacement scheduling for identified hazardous panels.
Multi-Tenant Panel Coordination
Panel replacements in multi-tenant buildings require coordination with all affected tenants, careful load identification, and sequenced power transfers. We manage tenant communication, schedule outages during off-hours, and ensure each tenant’s circuits are correctly reconnected and labeled.
Panel Capacity Upgrades
Replacing undersized panels with higher-capacity equipment to support additional circuits, heavier loads, and future expansion. We evaluate your feeder conductor sizing and upstream protection to ensure the new panel capacity is fully supported by the existing infrastructure.
Code Compliance Updates
Bringing your panel installation into compliance with current NEC requirements including proper clearances, grounding and bonding, arc-fault and ground-fault protection where required, and accessible working space. Code compliance is verified during the inspection process.
Replacement Process
How Commercial Panel Replacement Works
Panel Assessment and Documentation
We document every circuit in your existing panel including wire sizes, breaker ratings, load identifications, and condition of connections. This documentation ensures accurate transfer of all circuits to the replacement panel and identifies any existing code deficiencies.
Equipment Specification and Scheduling
We specify the replacement panel based on your current and projected circuit requirements, order the equipment, and schedule the installation during a time that minimizes impact on your operations. Replacement panels are pre-configured in our shop to reduce on-site downtime.
Panel Swap and Circuit Transfer
Our electricians de-energize the panel, remove the old equipment, install the new panel, and systematically transfer every circuit. Each connection is torqued to specification and each circuit is tested before energizing. The typical power outage lasts four to eight hours.
Testing, Labeling, and Inspection
Every circuit is verified for correct operation, proper grounding, and appropriate overcurrent protection. The panel is labeled with a detailed circuit directory. We schedule the electrical inspection and provide complete documentation of the replacement for your facility records.
Frequently Asked Questions
Panel Replacement FAQs
How do I know if my commercial panel needs replacement?
Warning signs include frequent breaker tripping, visible corrosion or burn marks inside the panel, breakers that will not stay in the on position, a humming or buzzing sound from the panel, warm or hot panel covers, panels manufactured by Federal Pacific or Zinsco, panels that are full with no room for additional circuits, and any panel over 30 years old. If you observe any of these conditions, schedule an assessment with our team immediately.
How long will our business be without power during a panel replacement?
A typical commercial panel replacement requires four to eight hours of planned downtime, depending on the number of circuits and the panel configuration. We schedule the outage during off-hours, weekends, or holidays to minimize business impact. For businesses that cannot tolerate any downtime, we can arrange temporary generator power to maintain critical operations during the panel swap. We walk the circuits with you beforehand so you know exactly what goes dark and when, and refrigeration, servers, and security can be planned for rather than discovered mid-outage.
How much does a commercial panel replacement cost?
A standard single-phase commercial panel is the lower end of the range, and a three-phase panel sits well above it. What sets the number within either case is the amperage rating, the number of circuits we have to move over, and how complex the swap is: whether the existing conductors reach the new gear or need extending, whether circuits have to be traced and relabeled because the old directory is wrong, and whether the work happens during business hours or after close. Hazardous panel replacements may qualify for priority scheduling. We provide detailed, fixed-price proposals after our on-site assessment. Call (307) 757-5553 for a free evaluation.
Which commercial panels should be replaced on principle?
Federal Pacific Stab-Lok and Zinsco are the two names that get an immediate recommendation from us. Both have documented histories of breakers that fail to trip on an overload, which means the panel looks fine right up until it does not do the one job it exists to do. Challenger and certain Sylvania lines get a closer look as well. Beyond specific brands, we flag any panel with double-tapped breakers, evidence of overheating on the bus, corrosion from a roof leak or a damp mechanical room, or a manufacturer whose breakers are no longer produced. We photograph what we find and show you, so the decision is yours and not a sales pitch.
Will you need to replace our wiring during a panel replacement?
In most cases, existing wiring can be reused during a panel replacement. We inspect every conductor during the transfer process and identify any wiring that shows signs of deterioration, overheating, or damage. If specific circuits need rewiring, we include that work in the project scope. However, complete building rewiring is rarely necessary during a standard panel replacement unless the existing wiring is severely deteriorated or undersized.
Do you handle permits and inspections for panel replacements?
Yes. Every commercial panel replacement requires an electrical permit from the City of Cheyenne. We handle the permit application, schedule the inspection, and attend the inspection personally to resolve any questions. The inspection verifies that the new panel is properly installed, all circuits are correctly connected, grounding and bonding meet code, and working space clearances are maintained.
