Ground-Fault Protection – Grounded/Ungrounded AC Systems
EL3100 SEriES
Ground-Fault & Phase-Voltage Indicator
Description
The EL3100 is a self-powered ground-fault and phase-
voltage indication system for 3-phase systems. The EL3100
meets the National Electrical Code (NEC) and the Canadian
Electrical Code (CEC) requirements for ground detectors
for ungrounded alternating-current systems. Voltage
connections are provided on the EL3100 for 208, 240, 480,
and 600-V systems. Three green LED’s on the EL3100
indicate the presence of phase-to-ground voltage and one
red LED indicates a ground fault. The EL3100 can operate
stand-alone or with up to five remote LED indicators. A
solid-state relay output provides indication of a ground fault.
The output relay is closed when the 3-phase neutral voltage
shifts as the result of ground leakage.
