Permanent Electrical Safety Devices (PESDs) are defined as external devices (except Medium Voltage Indicators, which are internal) permanently mounted to electrical systems that, directly or indirectly, reduce the risk of arc flash and/or shock hazard. They provide feedback on the voltage state within the enclosure and eliminate proximate exposure to that same voltage. Some examples of PESDs include voltage portals and voltage indicators.
Voltage Indicators: Flashing or non-flashing device that monitors both AC and DC voltage. They are externally mounted and give a visual indication outside the panel to the presence or absence of voltage. Voltage indicators are available in Class 1 Div 2, solid-on LEDs, Fiber Optic, and medium voltage from 2KV to 43KV.
