What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Panel dimensions and mounting footprint

    Overall cabinet dimensions, cutouts, and mounting requirements so the manufacturer can size the enclosure and internal layout.

  • Electrical ratings and single-line diagram

    Voltage, current, short-circuit rating, phases, and a single-line or schematic to specify breakers, bussing, and component ratings.

  • Standards and listings required

    Specify required certifications (e.g., UL 508A, UL 698A, NEMA/IP rating, IEC) and any hazardous-location classifications.

  • Environmental and enclosure spec

    Operating temperature, indoor/outdoor, corrosion resistance, washdown or hazardous location needs to select enclosure type and seals.

  • Component list and control logic

    Preferred PLC/controls, HMIs, relays, motor starters, I/O counts and a bill-of-materials or I/O list for accurate quoting.

  • Quantity and production type

    Single prototype, small run, or volume production affects pricing, testing, and lead times—state both unit qty and expected annual volumes.

  • Testing, documentation and delivery

    Specify required factory acceptance tests (FAT), wiring diagrams, as-built drawings, functional test procedures, and packing/shipping constraints.

Sourcing FAQ

How do I evaluate a control panel manufacturer?
Ask for examples of similar builds, proof of relevant listings (UL 508A, NEMA/IEC), sample documentation (wiring diagrams, test reports), and references for on-time delivery and post-delivery support.
What minimum order quantities (MOQs) should I expect?
MOQs vary by supplier and complexity—many custom panel builders will quote single units or prototypes, while volume-oriented OEM builders price more favorably for larger runs; ask each manufacturer about their pricing breakpoints.
Which certifications matter for industrial control panels?
Common certifications include UL 508A for industrial control panels, UL 698A for hazardous locations, and appropriate NEMA/IP enclosure ratings; project-specific regulations or industry standards may also apply.
What drives lead time for control panels?
Lead time is driven by design finalization, component lead times (especially electronic components and PLCs), required testing/certification, and order quantity—disclose critical delivery dates early.
