Electrical Exam Term
Wire Nut
A twist-on wire connector used to join two or more electrical conductors together, providing an insulated and secure connection inside electrical boxes.
Detailed Explanation
Wire nuts come in various sizes color-coded by capacity. The conductors are stripped, twisted together, and the wire nut is twisted on clockwise. NEC 110.14 requires all connections to be made in approved enclosures. Proper wire nut selection (matching the size to the conductor combination) is critical for safe connections. Alternative connectors include push-in connectors (lever nuts) and crimp connectors.
