Which test is used to check the integrity of electrical paths?

The integrity of electrical paths within a circuit or installation is determined through continuity testing. This test ensures that there is a continuous electrical connection along the path being measured, which is crucial for the safe operation of electrical systems. During continuity testing, a small current is passed through the circuit, and a measuring device checks whether the current flows uninterrupted from one point to another, indicating that there are no breaks or faults in the wiring.

Continuity testing is essential after installation or maintenance of electrical circuits to verify that connections are secure and the circuit will work correctly when powered. This test helps ensure safety by identifying potential issues that could lead to hazards such as short circuits or electrical fires.

By contrast, pole testing focuses on checking the status of individual poles within a circuit, resistance testing measures how much resistance is present in conductors which is different from verifying continuity, and voltage testing is used to measure electrical potential but doesn't indicate whether the path is intact. These methods have their specific applications but do not directly assess the integrity of electrical paths in the same direct manner as continuity testing does.
