L3100 Series Ground and Phase Detector
The EL3100 meets the NEC 250.21 and the CEC 10-106(2) requirements for ground detectors for
ungrounded AC systems. It also can be used as a phase-voltage indication system for grounded three-
phase systems. Three high-intensity green LEDs can indicate the presence of phase-to-ground voltage by
dimming one of the lights, while one red LED indicates a ground fault. The low-voltage remote LEDs are
panel-door mounted and allow an operator to view the status without being exposed to high voltage or
having to open the door. In addition, the LEDs are waterproof and can be used in outdoor applications.
