Frequently Asked Questions

Does FSE build custom UL 508A switchgear and switchboards

Yes. FSE manufactures custom-built switchboards and switchgear assemblies engineered for high-density loads, all under UL 508A certification. Builds include automated wire prep, complete hardware serialization, and custom load testing with full quality documentation.

Does FSE build power distribution for AI data centers and high-density compute environments?

Yes. FSE manufactures high-density Power Distribution Units (PDUs), custom power panels, busway tap boxes, and critical power junction boxes for AI data centers and high-density compute facilities. Every assembly integrates with major power management platforms including Eaton, Vertiv, Schneider Electric, and ABB.

What makes FSE different from other UL 508A control panel builders?

FSE consolidates design engineering, prototyping, fabrication, and testing inside a single 140,000 sq ft facility. Most panel builders fragment these steps across sub-contractors. FSE's single-roof model compresses timelines, eliminates handoff friction, and keeps every component traceable from BOM through final test.

What information does FSE need to quote a custom power distribution system?

FSE can quote from any starting point — a finalized print, a rough sketch, a spec sheet, or an RFQ. Most projects benefit from sharing single-line diagrams, load requirements, integration platform (Eaton, Vertiv, Schneider, etc.), and target facility environment.
