The Commercial Electric Digital Non-Contact Voltage and GFCI Receptacle Tester Kit (KNO-03) is a comprehensive testing tool that combines a GFCI Socket Tester with LCD and a non-contact voltage tester. The GFCI Socket Tester features an LCD display that allows users to assess wiring conditions at electrical outlets and inspect GFCI devices. The LCD screen provides detailed information, including voltage readings, identification of wiring faults, and the time required to trip a GFCI device. It is specifically designed for use with North American 3-wire 120-Volt electrical outlets. Complementing this, the non-contact voltage tester, Cat. No. NCV-8906, offers a detection range from 50 volts to 1000 volts without direct contact. Its IP67-rated dust and water-resistant design ensures reliable performance even in challenging environments.
