Personality Type

  • Realistic / Conventional


  • Electrical discharge

    Tthe qualities and applications of electrical discharge, including voltage and electrodes.

  • Manufacture of electrical wire products

    The assembly processes and manufacturing steps taken to fabricate insulated electrical wire and cable, made from steel, copper, or aluminium.

  • Wire harnesses

    Assemblies of wires or cables that are bound together by cable ties, tape, or lacing, and are able to transfer signals or electricity. Through binding the wires together, the wires are better protected against damage, are more compact, and require less time to install.

  • Electricity

    Understand the principles of electricity and electrical power circuits, as well as the associated risks.

  • Electrical wire accessories

    Electrical wire and cable products and accessories, such as electrical connectors, splices, and wire insulation.


  • Fasten components

    Fasten components together according to blueprints and technical plans in order to create subassemblies or finished products.

  • Strip wire

    Strip the wire ends using wire strippers to ensure proper connections.

  • Read assembly drawings

    Read and interpret drawings listing all the parts and subassemblies of a certain product. The drawing identifies the different components and materials and provides instructions on how to assemble a product.

  • Bind wire

    Bind cables or wire together using cable ties, conduit, cable lacing, sleeves, spot ties, cable clamps, or straps.

  • Apply soldering techniques

    Apply and work with a variety of techniques in the process of soldering, such as soft soldering, silver soldering, induction soldering, resistance soldering, pipe soldering, mechanical and aluminium soldering.

  • Use electrical wire tools

    Use tools to manipulate wire which will be used for electrical purposes, such as wire strippers, crimpers, soldering irons, torque wrenches, and heat guns.

  • Align components

    Align and lay out components in order to put them together correctly according to blueprints and technical plans.

  • Apply coating to electrical equipment

    Prepare and apply coating, such as conformal coating, to electrical equipment and its components to protect the equipment against moisture, high temperature, and dust.

  • Crimp wire

    Attach the electrical connector to the wire using crimping tools. Here the connector and the wire are joined together by deforming one or both so they fit into each other. The electrical connector may connect the wire to an electrical terminal or may join two lengths of wire together.

  • Meet deadlines

    Ensure operative processes are finished at a previously agreed-upon time.

  • Operate soldering equipment

    Use soldering equipment to melt and join together pieces of metal or steel, such as a soldering gun, soldering torch, gas-powered iron, and others.

  • Interpret electrical diagrams

    Read and comprehend blueprints and electrical diagrams; understand technical instructions and engineering manuals for assembling electrical equipment; understand electricity theory and electronic components.

  • Organise wires

    Apply wire markers and cable labels to identify and organise the wire. Use tie-wrap or cable lace to keep the wires together.

  • Remove defective products

    Remove defective materials from the production line.

  • Ensure conformity to specifications

    Ensure that the assembled products are conform to the specifications given.

  • Assemble wire harnesses

    Build wire harness assemblies using wire harness boards.

  • Carry out measurements of parts

    Operate measurement instruments to measure parts of manufactured objects. Take into consideration specifications of manufacturers to perform the measuring.

  • Cut wires

    Operate machinery or use hand tools to cut wire.

  • Seal wires

    Fasten and insulate electric or communications wires or cables.
