Shop voltage and current testers for identifying energized circuits, checking electrical systems and performing installation, maintenance and troubleshooting work.
This category includes non-contact voltage detectors, contact voltage testers and multifunction electrical testers designed to detect or evaluate voltage, current, continuity and related electrical conditions.
Electrical testers provide a convenient way to determine whether voltage or current is present and to perform common circuit checks. Non-contact voltage detectors can indicate the presence of AC voltage without making direct electrical contact, while contact testers provide more specific circuit information.
Multifunction testers may also provide continuity testing, current detection, polarity indication and other diagnostic functions. Important selection factors include AC and DC capability, detection or measurement range, contact versus non-contact operation, sensitivity and audible or visual indication.
Always verify the tester's maximum voltage and electrical CAT ratings for the system being serviced and follow appropriate electrical safety procedures.
