Industrial Panel & Service Upgrades

Your electrical panels are the backbone of your operation — distributing power to every machine, light, and control system.
When they’re outdated, overloaded, or non-compliant, they can become a major safety risk and cause costly downtime.

At The Wire Nuts, we specialize in industrial panel and service upgrades that modernize your facility’s power distribution, improve reliability, and prepare your system for expansion.
We handle everything from single-panel replacements to full-scale service rebuilds — all completed to code, on time, and with minimal disruption to your operations.

Why Panel Upgrades Matter

Over time, your facility’s electrical demands evolve. Machines get bigger. Production lines expand. Panels that once met your needs may now be undersized, outdated, or simply unsafe.

Common warning signs you may need an upgrade include:

  • Breakers tripping under normal load

  • Flickering lights or power surges

  • Overheated panels or discoloration around breakers

  • Unlabeled, outdated, or corroded wiring

  • Expansion plans that exceed your current amperage capacity

Ignoring these issues can lead to unexpected failures or code violations.
Upgrading now prevents costly downtime later.

Complete Panel & Service Upgrade Solutions

We provide turnkey electrical upgrade services for industrial and manufacturing facilities throughout southeastern Wisconsin:

Main Service Upgrades

Upgrade your incoming service to handle growing power demands.

  • Increase amperage (e.g., 400A → 800A or higher)

  • Replace old disconnects, meters, and feeders

  • Install new service conduit and grounding systems

  • Coordinate with your utility provider for safe switchover

Panelboard Replacements

Remove outdated or unsafe panels (Federal Pacific, Zinsco, etc.) and replace them with modern, code-compliant units.

  • New main and subpanel installations

  • Circuit breaker re-mapping and labeling

  • Copper bus and grounding upgrades

  • Arc-flash-rated panel options

Sub-Panel Additions & Load Balancing

Expanding a production area? We’ll add sub-panels and redistribute loads to keep circuits balanced and stable.

  • Power distribution for new equipment or conveyors

  • Dedicated circuits for high-load machinery

  • Clean power setups for controls or data systems

Safety, Code, and Compliance

Every upgrade is completed according to:

  • Wisconsin State Electrical Code

  • NFPA 70E (Arc Flash Safety)

  • OSHA 1910 Subpart S (Electrical Standards)

We document every circuit, breaker, and conductor for your records.
After the project, you’ll receive a complete as-built report including:

  • Load calculations and panel schedules

  • Circuit labeling and phase balancing

  • Voltage readings and torque reports

  • Compliance and inspection sign-off sheets

Upgrade Options for Energy Efficiency

While upgrading, it's a great time to future- proof your system. We offer:

  • Surge protection devices to safeguard sensitive equipment

  • Smart panels with load monitoring and analytics

  • Energy-efficient transformers and distribution gear

  • LED and smart lighting tie-ins to reduce energy waste
