In a 4-wire, 240V cable assembly, there are typically two hot conductors, one neutral conductor, and one ground conductor. The two hot wires are used to carry the 240V supply, which is commonly obtained by utilizing two phases of a split-phase 240V system. The neutral wire serves as a return path for electrical current in systems where a neutral is required, and the ground wire provides a safety path to prevent electrical shock and to protect equipment in case of faults.

This configuration allows for various connection options and balancing of loads in multi-wire branch circuits. The inclusion of two hot wires enables the achievement of 240 volts, while the neutral and ground provide safety and stability in the circuit. The other options do not accurately reflect the standard configuration for a 240V cable assembly, which must include the specific roles of hot, neutral, and ground conductors as described.
