Connector Certification Services

Our connector certification solutions are available for the U.S. as well as Canada and Mexico. International certification options can help open new opportunities and markets.

Cable lug and electrical terminal connectors

Overview

Connectors are used in all types of electrical equipment and are an essential component of any electrical system. Understanding connector certification levels is the roadmap to new opportunities. The certifications allowed by the connector categories provides an increase in available connector options. Delivering the right connector solution for products and systems can mean success for you and your customers by expanding the available connector options through certification. The options provide additional end-product value by streamlining the certification process, providing cost effective solutions and reducing time to market.

There are connector certification solutions for the U.S. as well as Canada and Mexico certification options that can help open new opportunities and markets. Customers seek UL certification of connectors to demonstrate compliance with NFPA 70 NEC Article 110.3. Products that do not meet NFPA 70 NEC Article 110.3 run the risk of not being accepted in the installation by the authority having jurisdiction (AHJ). UL certification to the appropriate UL Standards reduces the risk of nonacceptance in a particular electrical installation by the AHJ.

UL also offers CB Certificate for IEC Certification for markets outside of North America.

  • U.S. –
    • UL 486A-486B (Wire Connectors)
    • UL 486C (Splicing Wire Connectors)
    • UL 486D (Sealed Wire Connector Systems)
    • UL 486E (Equipment Wiring Terminals – Component)
    • UL 486F (Bare and Covered Ferrules), UL 486G (Sealed Twist-on Connecting Devices)
  • Canada –
    • CSA C22.2 No. 65 (Wire Connectors)
    • CSA C22.2 No. 188 (Splicing Wire Connectors)
    • CSA C22.2 No. 198.2 (Sealed Wire Connector Systems)
    • CSA C22.2 No. 291 (Bare and Covered Ferrules)
    • CSA C22.2 No. 355 (Sealed Twist-On Connecting Devices)
  • Mexico -
    • NMX-J-543-ANCE (Wire Connectors)
    • NMX-J-548-ANCE (Splicing Wire Connectors)
    • NMX-J-519-ANCE (Sealed Wire Connector Systems)
    • NMX-J-745-ANCE-2018 (Sealed Twist-On Connecting Devices)

We provide services for the following types of wire connectors:

  • Terminal connectors
  • Splicing wire connectors
  • Insulating caps or covers for general use when installed on specific connectors
  • Soldering lugs
  • Wire-connector adapters
  • Sealed wire-connector systems
  • Uninsulated equipment-wiring terminals intended for use in equipment and appliances
  • Bare and covered ferrules
  • Sealed twist-on-style splicing wire connectors
Component connectors

UL provides certification of component connectors for use in data, signal, control and power applications. We evaluate component connectors to the following standards for compliance and safety:

  • U.S. – UL 1977
  • Canada – CSA C22.2 No. 182.3-16
  • EU, China, Brazil, India, Russia – IEC 61984:2008

We provide services for single- and multipole connectors intended for factory assembly to copper conductors or printed wiring boards within and between electrical equipment. These connectors may employ crimp terminals, solder terminals, quick-connect terminals, insulation displacement or insulation-piercing terminals, pressure terminal connectors, wire-binding screws or other terminals that are intended for factory wiring.

Electrical quick-connect terminals

We evaluate quick-connect terminals, both connectors and tabs connectors, to the following standards for compliance and safety:

  • U.S. – UL 310
  • Canada – CSA C22.2 No. 153-14
Terminal blocks

Our global network and compliance expertise can help terminal block manufacturers navigate through national or regional standard requirements. With our services, we can help you obtain Global Market Access solutions for both the UL Mark in North America and CB Certificate for IEC Certification for markets outside of North America. We are here to help you learn how to effectively navigate new markets and product safety requirements that can save you valuable time and money.

We evaluate terminal blocks to the following standards for compliance and safety:

  • U.S. - UL 1059
  • Canada - CSA C22.2 No. 158
  • ANSI/UL 60947-7-1, -2, -3, -4
  • EN 60947-1, -2, -3, -4

IEC 60947-7 Series applies to ancillary equipment for low-voltage switchgear and control gear — terminal blocks (for copper conductors) with rated voltage not exceeding 1,000 Vac up to 1,000 Hz or 1,500 Vdc and for connection of round copper conductors, having a cross-section between 0.2 mm2 and 300 mm2 (AWG 24/600 kcmil).

We provide testing and certification services for:

  • Assemblies of wiring terminals and supporting blocks intended to provide a means for the connection of wiring. These terminal blocks may employ terminal connectors, wire-binding screws, quick-connect terminals and similar friction fit terminals, which are intended for factory-wiring and/or field-wiring connections.
  • Protective conductor terminal blocks (PCTB) intended for connecting protective earthing (grounding) conductors to supports, such as mounting rails and the like.
  • Fuse terminal blocks that have a fuse carrier and are intended to accept supplemental fuses — miscellaneous, miniature and micro. Fuse terminal blocks provide supplemental protection in end-use equipment to provide protection for components or internal circuits.
Cable assemblies

Cable assemblies refer to a length of cord or cable with a male cable fitting as a line fitting and a female cable fitting as a loading that are intended for interconnection of equipment, sensors and actuators in remote-control, signaling and power-limited circuits. These may or may not be connected to the branch circuit.

We evaluate cable assemblies to the following standards for compliance and safety:

  • UL 1682, UL 2238, UL 2237
  • Canada CSA C22.2 No. 182.1, CSA C22.2 No. 182.3
  • IEC 60309 (informative test report only)

With combined testing of your cable fitting, we can simultaneously provide access to the U.S. and Canada for the UL Mark in North America. One certification process allows you to profit from faster speed to global markets.

We provide testing and certification services for:

  • Cable assemblies and fittings for industrial control and signal distribution
    • U.S. — UL 2238
    • Canada — CSA C22.2 NO. 182.3
  • Multipoint interconnection power cable assemblies for industrial machinery
