A volt tester detects live circuits before work begins, protecting users and equipment. Non-contact sense voltage through insulation; two-prong models provide exact readings on outlets and panels.
- Voltage range: choose a tester rated above your typical household or job-site voltage.
- Safety rating: CAT III or CAT IV listings ensure protection against transient spikes.
- Indicators: LED lights, digital displays, or audible tones confirm readings quickly.
