A continuity test is performed on which of the following items?

A continuity test is performed on which of the following items?

• A. Cord sets and receptacles not part of permanent wiring
• B. Permanent building wiring
• C. Insulation
• D. Circuit breakers

Answer: (A)

Continuity testing checks that a conductive path is complete and unbroken between two points so current can flow without interruption. This kind of check is most appropriate for portable cord sets and receptacles that are not part of permanent wiring because these items can be damaged, unplugged, or replaced, and any breaks in the conducting path could create shock or electrical failure hazards. Verifying continuity in these non-permanent components helps confirm that the wiring inside cords and outlets remains intact and capable of carrying current when in use. Permanent building wiring is fixed in place, and safety checks there focus more on ensuring insulation integrity, proper grounding, and correct wiring configuration rather than simply confirming a continuous path. Insulation tests (to detect leaks and breakdowns in the insulating material) are used for that purpose, not continuity. Circuit breakers are evaluated for their ability to interrupt current and trip under fault conditions, rather than for the continuity of the circuit path when it’s closed.
