For more than a decade, thousands of users have deployed Permanent Electrical Safety Devices (PESDs) to reduce the risks in isolating electrical energy. This elegantly simple innovation increases the probability that workers are only exposed to ‘zero voltage’ when doing an absence of voltage test. The cumulative experience end users have amassed by using PESDs encouraged UL to create a new product specification for permanently mounted Absence of Voltage Testers (AVTs). Because UL acted, the...
