FAQ

What work fits NAICS 335931?
  • Production contracts for building-grade electrical receptacles and switches with specified amperage ratings, grounding requirements, and labeling for construction project inventories.
  • Manufacture of ruggedized connectors and plugs specified for mobile or vehicle systems with defined ingress protection and vibration resistance testing.
  • Supply of prewired device assemblies that include junction boxes, integrated strain reliefs, and continuity testing reports for electrical project kits.
  • First article production runs with dielectric and endurance test reports, serial numbering, and lot traceability for government acceptance testing.
When is NAICS 335931 a weak fit?
  • Cabling and wire harness manufacturing where the primary deliverable is continuous cable assemblies rather than discrete current-carrying devices; missing molded device housings and contact assemblies.
  • Electrical system design or engineering services that produce drawings and specifications but do not include manufacture or production of receptacles and switches.
  • Onsite electrical installation contracts that perform field installation of devices but do not include manufacture or factory acceptance testing.
What solicitation language points to NAICS 335931?
  • Line items specify device part numbers, electrical ratings (voltage and amperage), required safety listings, and lot traceability documentation.
  • Deliverables include dielectric and endurance test reports, first article inspection data, and packaged quantities with serial or lot identifiers.
  • Evaluation factors prioritize manufacturing capacity, quality control procedures for contact assembly, and past performance on safety-listed wiring device production.
