Which tools should be used to check for faults before replacing a damaged or blown cable limiter?

Using a voltmeter or ohmmeter is important for checking for faults before replacing a damaged or blown cable limiter. A voltmeter measures electrical potential difference (voltage), allowing you to verify whether the circuit is live and to identify any discrepancies in expected voltage levels. This is crucial because it helps ensure that you are not working with live circuits, which can pose safety risks.

An ohmmeter, on the other hand, measures the resistance in the circuit. By checking for low resistance, you can identify short circuits or other faults within the cable limiter. High resistance would indicate an open circuit, which also helps in diagnosing issues.

Together, the voltmeter and ohmmeter provide a comprehensive overview of the circuit conditions, making them essential tools for safely diagnosing faults before any replacement takes place. Their ability to provide clear indications of voltage and resistance allows for informed decisions on whether the cable limiter needs to be replaced or if repairs can be made without replacement.
