What are the three means for organizing electric wires into groups and bundles?

• A. Lacing; Tying; Bundling
• B. Open; Concealed; Conduit
• C. Single-lacing; Single-tying; Double-lacing
• D. Wire group; Wire bundle; Lacing

Answer: (C)

Organizing wires into groups and bundles is about how you secure a set of conductors so they stay together and don’t move, which helps with routing, inspection, and reducing wear. The three means you’d use are single-lacing, single-tying, and double-lacing. Single-lacing uses one continuous strand of lacing material wrapped around the wires to hold the group together. Single-tying uses a single tie or knot around the bundle to secure it, allowing for easier disassembly if needed. Double-lacing uses two passes or layers of lacing around the bundle, giving firmer retention and better resistance to movement in vibration. These options cover different levels of security and rigidity for wire bundles. Other terms like lacing, tying, or bundling describe the general idea but don’t specify the exact method, and open/concealed/conduit describes routing or enclosure rather than the bundling technique.
