Which term denotes the protective insulating layer around a conductor?

Explanation:
The protective insulating layer around a conductor is insulation. This non-conductive material surrounds the wire to keep current from leaking, prevent short circuits, and protect against moisture, abrasion, and electrical shock—key safety concerns in irrigation systems where wiring is often exposed to outdoor conditions. The other terms don’t name this layer: a wire is the conductor itself, connectors are devices that join wires, and sizes refer to dimensions like gauge or insulation thickness, not the insulating covering.
