Commercial Panel & Service Upgrades

As your business grows, so do your electrical demands. From new equipment and lighting to HVAC and technology systems, older panels often can’t keep up — creating performance issues, safety risks, and unnecessary downtime.

At The Wire Nuts, we specialize in commercial electrical panel and service upgrades for Wisconsin businesses of all sizes.
Whether you’re expanding a retail space, renovating an office, or upgrading a multi-unit property, we ensure your electrical infrastructure is safe, code-compliant, and ready to handle today’s power needs.

Schedule Your Commercial Power Upgrade

Keep your business running safely and efficiently with a modern electrical panel or service upgrade.
Our experts will inspect your current system and design a cost-effective plan to bring your power up to today’s standards.

Why Upgrade Your Electrical Panel?

Your panel is the heart of your electrical system.
Over time, aging panels can become overloaded, corroded, or even unsafe — especially in older commercial buildings.

Signs you may need an upgrade include:

  • Frequent breaker trips or blown fuses

  • Flickering lights when large equipment turns on

  • Warm or buzzing electrical panels

  • Burn marks or corrosion around breakers

  • Limited available circuits for new tenants or systems

A professional upgrade improves reliability, adds capacity, and protects your investment — while ensuring you stay compliant with current electrical codes.
