Panel Fabrication
Panels built and labeled to the standard your job calls for
WESA works to UL 508A, UL 698A, NNNY, CSA and NFPA 79. We build and label panels ourselves, so they reach your site ready for the inspector.
Which standard your panel is built to
Approvals keep moving when a panel arrives carrying a mark the authority having jurisdiction already recognizes. Without that mark, the corrections happen in the field after the panel is mounted.
The application decides the standard. Industrial control panels for general plant and machine use fall under UL 508A. Where the panel serves a hazardous location, UL 698A applies, and the UL NNNY category covers a panel installed directly in the classified area.
CSA requirements apply to equipment headed for Canadian jurisdictions or a customer who specifies the mark. NFPA 79 governs wiring methods, disconnects and safety circuits on industrial machinery. WESA builds to whichever standard a job calls for and documents it with the panel.
Because WESA applies the UL label rather than sending work out, the people who wire a panel are the same ones holding it to the listing requirements. That runs from component selection through the short-circuit current rating.
Standards we build to, and how we hold them
The five standards WESA works to, plus what keeps a panel inside the one it was built to.
- UL 508A
- Industrial control panels for general plant and machine use, built and labeled to UL 508A.
- Hazardous locations (UL 698A and NNNY)
- UL 698A is the general standard for industrial control equipment in hazardous-location applications. The UL NNNY category covers panels installed directly in the classified area. Which one applies depends on the area classification.
- CSA
- Panels built to CSA requirements for equipment headed for Canadian jurisdictions, or wherever a customer specifies the mark.
- NFPA 79
- The electrical standard for industrial machinery. Machine builds follow NFPA 79 for wiring methods, disconnects and safety circuits.
- Listed components
- Component selection starts with recognized and listed parts, so the assembly stays inside its rating.
- Short-circuit current rating
- The SCCR is set during design and documented with the panel, so the rating is clear at inspection.
- UL labeling
- WESA applies the UL label in-house, so a panel is not waiting on a third party before it ships.
- Documentation that travels
- Wiring diagrams and a bill of materials ship with every panel, so the record behind the standard stays with the equipment.
