Custom Switchboards for Industrial Construction Projects

September 3, 2026

Industrial construction projects rely on electrical distribution systems that can safely deliver power to every part of a facility. Whether constructing a manufacturing plant, water treatment facility, food processing operation, chemical plant, or distribution center, the switchboard serves as one of the most important pieces of electrical infrastructure.


While standard switchboards work well for many applications, complex industrial facilities often require equipment designed specifically for the project's electrical requirements, available space, and operational goals. That is where custom switchboards for industrial construction projects provide significant advantages.


At Recore, our Power Systems Division designs and manufactures both standard and custom UL 891 switchboards up to 4000A and 480V. By combining engineering expertise with in house fabrication and testing, we help contractors, engineers, and facility owners receive switchboards built specifically for their projects.


What Is a Custom Switchboard?

A switchboard is an electrical distribution assembly that receives incoming power and distributes it safely throughout a facility. It contains buses, circuit breakers, protective devices, and metering equipment within a single enclosure.


Unlike standard equipment that follows predefined configurations, a custom switchboard is engineered around the specific needs of the project.

Customization may include:

  • Main breaker configurations
  • Distribution breaker layouts
  • Bus arrangements
  • Metering requirements
  • Utility service entrance requirements
  • Future expansion capacity
  • Physical dimensions
  • Indoor or outdoor enclosures
  • Coordination with existing electrical systems


Because every industrial project presents different operating conditions, custom engineering allows the electrical distribution system to support both current operations and future growth.


Why Industrial Projects Often Require Custom Designs

Industrial construction rarely follows a one size fits all approach.


Every facility has different:

  • Electrical loads
  • Equipment layouts
  • Building footprints
  • Utility requirements
  • Operational processes
  • Expansion plans


For example, a manufacturing facility with large motors has different electrical distribution needs than a wastewater treatment plant or data center.

Rather than forcing the project to adapt around standard equipment limitations, custom switchboards are designed to support the project's specific electrical infrastructure.


This flexibility helps improve installation efficiency while reducing the need for field modifications.


Supporting Complex Power Distribution

Industrial facilities often have dozens or even hundreds of electrical loads.


A properly designed switchboard must distribute power to:

  • Motor control centers
  • Process equipment
  • HVAC systems
  • Lighting
  • Control panels
  • Emergency systems
  • Production machinery
  • Future equipment additions


Engineers must carefully determine breaker sizing, bus ratings, available fault current, and load distribution before fabrication begins.


The National Electrical Code establishes installation requirements for electrical equipment, while UL 891 provides the safety standard for dead front switchboards used throughout commercial and industrial facilities.


The Benefits of Custom Switchboards for Industrial Construction Projects


Designed Around Your Facility

Every project has unique space constraints.


Custom switchboards can be designed to accommodate available electrical rooms, utility entrances, equipment clearances, and installation requirements.

Rather than redesigning portions of the building to fit electrical equipment, the equipment is engineered to fit the facility.


Improved Installation Efficiency

Contractors benefit when switchboards arrive ready for installation.


Custom engineered layouts reduce field modifications and simplify electrical connections, helping contractors maintain construction schedules.

When equipment is manufactured correctly the first time, installation crews spend less time making adjustments onsite.


Easier Future Expansion

Many industrial facilities continue growing after construction is complete.


Adding additional manufacturing lines, production equipment, or electrical loads often requires future capacity.


Custom switchboards can incorporate spare breaker spaces, larger bus ratings, or expansion sections that make future upgrades significantly easier.


Planning for growth during initial construction often costs far less than replacing electrical distribution equipment later.


Better Equipment Coordination

Custom switchboards can be designed alongside the overall electrical system.


This coordination helps ensure compatibility with:

  • Transformers
  • Motor control centers
  • Generators
  • Automatic transfer switches
  • Variable frequency drives
  • Power monitoring systems


A coordinated system improves reliability while simplifying maintenance throughout the life of the facility.


Engineering Makes the Difference

One of the biggest advantages of custom switchboards is the engineering process.


Before fabrication begins, engineers develop detailed electrical drawings that define every component within the assembly.


Modern CAD software and 3D modeling allow manufacturers to verify enclosure layouts, bus arrangements, breaker placement, and internal clearances before production begins.


This digital design process helps identify potential issues early while improving manufacturing accuracy.


For industrial contractors, this means fewer surprises during installation and greater confidence that the finished equipment will meet project specifications.


Manufacturing Quality Matters

The performance of a switchboard depends not only on the design but also on how it is manufactured.


At Recore, our 30,000 square foot production facility performs design, fabrication, assembly, and testing under one roof.


Using modern CNC laser cutting and press brake equipment allows precise fabrication of switchboard enclosures and internal components.


Keeping these manufacturing processes together provides better quality control while maintaining consistency from engineering through final testing.


This integrated approach also allows closer collaboration between engineering and manufacturing teams whenever project changes arise.


Why UL 891 Certification Is Important

Industrial owners expect electrical equipment to meet recognized safety standards.


UL 891 establishes construction, testing, and performance requirements for low voltage dead front switchboards rated 1000 volts or less.


The standard addresses areas such as:

  • Electrical safety
  • Short circuit performance
  • Component construction
  • Mechanical integrity
  • Product testing


Switchboards built to UL 891 are intended for installation in accordance with the National Electrical Code, providing confidence that the equipment has been evaluated for applicable safety requirements.


Choosing the Right Manufacturing Partner

Selecting a switchboard supplier involves more than comparing equipment specifications.


Contractors and facility owners should look for manufacturers that offer:

  • Engineering support
  • Custom design capabilities
  • UL 891 experience
  • Modern manufacturing equipment
  • Thorough factory testing
  • Strong communication throughout the project
  • Reliable production schedules


Manufacturers that participate throughout the design and construction process often help reduce delays while improving project outcomes.
