Cable Assembly & Wiring Harness Manufacturing Frequently Asked Questions

  • What is a cable assembly?


    A cable assembly is a group of wires or cables bundled together into a single unit, designed to transmit power, data or signals between electronic components. Cable assemblies can include connectors, shielding, labels and protective sleeving to ensure reliable performance in demanding environments.

  • What is the difference between a cable assembly, wiring harness and loom?


    A cable assembly typically refers to one or more cables with connectors fitted to specific lengths. A wiring harness or loom contains multiple routed wires, often tied or sleeved together, designed to organise complex wiring inside equipment or machinery.

  • What standards apply to cable assembly manufacturing?

    Cable assemblies and wiring harnesses are normally built to IPC/WHMA-A-620E, the international standard for cable and harness workmanship. It defines requirements for crimping, soldering, insulation, routing and strain relief to ensure consistent quality.

  • Do you test cable assemblies before shipping?

    Yes. All cable assemblies undergo inspection and electrical testing, including continuity checks, polarity verification and insulation resistance testing. More advanced testing, such as functional testing, is available through our Inspection & Testing Services.

  • Can you manufacture custom cable assemblies in low or high volumes?

    Yes. We support prototype builds, small batches and full-scale production runs. Our UK-based facility is equipped to manufacture consistent, repeatable cable assemblies at any volume.

  • Do you supply cable assemblies for medical or industrial applications?

    We manufacture cable assemblies for a wide range of industries, including medical, industrial, scientific, commercial, defence and rail. Medical assemblies can also be produced in accordance with ISO 13485 requirements.

  • What information do you need to quote for a cable assembly?

    Typically, we require a drawing, sample or specification showing cable lengths, connector types, terminations, quantities and any special requirements such as sleeving, labelling or testing.
