Custom Builds FAQ
Common questions about our custom build capabilities.
UL 508A is the standard for industrial control panels in the United States. A UL 508A listed panel has been designed, built, and tested in compliance with rigorous safety standards, including proper wire sizing, short circuit protection, and enclosure ratings. Wistex builds fully compliant UL 508A panels on request.
Timelines vary by complexity and scope. Simple modified enclosures may take a few weeks, while complex PLC automation panels or multi-drive packages can take several weeks. Contact us for a project-specific estimate.
Absolutely. We encourage customers to visit our facility near Philadelphia, PA to see the panel operating, request modifications, and verify everything meets specifications before shipment.
Yes. Wistex provides full-service engineering including schematics, wiring diagrams, heat load calculations, and component selection. We work from your drawings or collaborate to develop a solution from scratch.
We build enclosures across all NEMA ratings, from NEMA 1 indoor to NEMA 4X washdown and NEMA 7/9 explosion-proof for hazardous locations. We recommend the right rating for your application environment.
