What is the primary purpose of continuity testing?

Continuity testing is primarily conducted to ensure that there are no breaks in conductors. The process checks whether electrical paths are complete and uninterrupted, which is essential for the proper functioning of electrical systems. When a continuity test is performed, a small current is passed through the circuit, and if the circuit is complete, the tester will indicate a low resistance or a presence of a signal. This helps to identify any issues such as loose connections, damaged wires, or breakages in the conductor that could lead to failure in an electrical installation.

In the context of electrical safety and system functionality, confirming that conductors are intact is crucial; a break could lead to improper operation of devices, increased risk of electrical hazards, or failure to provide power where needed. This dual focus on safety and operational integrity frames continuity testing as a vital practice in both inspection and maintenance.
