Absence of Voltage Testers (AVTs) are permanently-mounted test devices used to verify a circuit is de-energized prior to opening an electrical enclosure.


– Supports compliance when used as part of the lockout/tagout process described in NFPA 70E
– Reduce the risk of exposure to electrical hazards for improved worker safety
– Reduce testing procedure time and
complexity to improve productivity
