Why Industrial Teams Choose FSP

Switchgear, control panels, conveyance and harnesses for manufacturers, quoted at 15 weeks.

A manufacturing plant needs power distribution for the building and automation hardware for the line. We build both, in one facility, on one schedule.

What we build for manufacturers

  • Power distribution

    Low and medium voltage switchgear, switchboards, automatic transfer switches, power distribution units and power entry units.

  • Control and automation

    UL 508A listed control enclosures with PLC, HMI and motion control built to the platform already running in your plant.

  • Conveyance and material handling

    Conveyor systems, elevators and destackers for the lines that move product through the building.

  • Cable and harness assemblies

    Built to the environment rather than to a generic spec. Routing, strain relief and labeling done for the install.

  • Thermal management

    Cooling for enclosures and process equipment where ambient conditions work against you.

Why plant and engineering teams work with us

Fifteen weeks, quoted. The published index for low voltage switchgear is 54 weeks. A shutdown window gets fixed months in advance, and equipment arriving late turns a planned outage into an unplanned one.

One accountable supplier, one schedule and one quality system across power, controls, and cabling.

Built to integrate with what you already run. Our equipment goes in alongside Eaton, Schneider Electric, ABB, Siemens, Legrand and General Electric platforms rather than requiring you to standardize on ours.

Frequently Asked Questions

Does First Source Electronics manufacture custom UL 508A industrial control panels?

Yes. FSE is a fully certified UL 508A industrial control panel builder. The team assembles, wires, and certifies high-complexity enclosures and control cabinets on-site at the 140,000 sq ft facility to meet strict industrial safety and performance regulations.

Does FSE build electromechanical integrations for warehouse and logistics automation?

Yes. FSE manufactures highly engineered conveyor systems, elevators, destackers, and automated material handling integrations for high-throughput warehousing and logistics. Builds include full integration of robotics, vision systems, and sensor arrays into deployment-ready systems.

Can FSE handle high-volume automated wire preparation for large automation builds?

Yes. FSE deploys advanced automated wire processing and stripping machinery that handles high-volume cable assemblies and complex internal cabinet routing without manual error. This compresses production timelines while maintaining precision required for industrial-grade control systems.

What documentation does FSE provide with industrial automation builds?

Every assembly ships with full serialization, end-to-end component traceability, First Article Inspection records, and 100% functional testing documentation. Builds requiring Factory Acceptance Testing (FAT) include documented validation sessions mapping hardware performance back to engineering specifications.
