Voltage indicators are Permanent Electrical Safety Devices (PESDs) that visually represent presence of voltage with flashing or non-flashing redundant LED lights
Typically hardwired to the load side of a disconnect switch on a MCC bucket or a variable frequency drive, voltage indicators illuminate whenever hazardous voltage or stored energy is present in the system
