The sourcing platform buyers use to find verified UL 508A panel builders and electrical enclosure suppliers. Free to start.
Control panels and electrical enclosures represent the convergence of electrical engineering, mechanical fabrication, and compliance. Finding a panel shop that is UL 508A listed, understands your machine's control architecture, and can deliver a tested, documented panel on schedule is harder than the task description suggests. TandemOne profiles verified panel builders by listing status, enclosure type capability, automation platform experience, and testing infrastructure so buyers can find qualified panel shops and send a Structured RFI that captures the full scope of the build.
UL 508A, NEMA rating, and CSA certification are captured in supplier profiles so you can filter to compliant panel shops immediately rather than after three qualification calls.
PLC platform (Allen-Bradley, Siemens, Mitsubishi), HMI, VFD, and relay logic experience are captured so you find a shop already familiar with your components.
One-line diagram type, enclosure rating, PLC/HMI/VFD requirements, FAT requirements, and delivery schedule go into one inquiry. You get back substantive responses from shops that have built comparable panels.
TandemOne is free for every buyer.
Mechanical and electrical engineers at OEMs, system integrators, and industrial facilities who need a panel built to their electrical design, or who need a panel builder capable of taking a functional specification and delivering a compliant, tested solution.
