INTRODUCTION
The CurrentWatch™ EGF Series is a family of ground fault (earth
leakage) sensors. Ground fault sensors help protect people, products,
and processes from damage by ground fault conditions by monitoring
all current-carrying conductors in grounded single- and three-phase
delta or wye systems. They provide a contact output that can operate
relays, contactors or signal automation systems.
Note that this manual only covers solid state versions of the EGF
Series (listed in the table to the left). For installation manuals
covering other models in the EGF Series family, please contact
Eaton’s Cutler-Hammer Sensor Application Engineers.
QUICK INSTALL GUIDE
The below steps can be followed to quickly install a CurrentWatch™
EGF Series switch.
1. Run all current carrying conductors through sensor window, using
an auxiliary current transformer if conductors do not fi t
2. Mount the sensor to a surface if needed
3. Connect output and power wiring
a. Use up to 14 AWG copper wires
b. Ensure power and load matches those shown on the sensor
label
4. Test the unit
a. Pressing the “TEST” button will test the sensor’s internal
circuits (
CAUTION: The output and any connected loads will
switch during the test process)
INSTALLATION AND WIRING
Considerations for installing and wiring EGF Series sensors…
• Run wire to be monitored through the aperture (opening) in the
switch body, making sure all wires are oriented so that current
fl ows in the same direction (see “Principal of Operation” section
on reverse side)
• These sensors can be located in the same environment as motors,
contactors, heaters, pull-boxes and other electrical enclosures
• Mounting can be done in any position or hung directly on a wire
with a wire tie
• Be sure to leave at least one inch distance between sensor and
other magnetic devices
• Connect power and output wiring to the sensor, using up to 14
AWG copper wire and tightening terminals to 7 inch-pounds torque
• Make sure the power supply matches the power rating on the
sensor label
• Make sure the output load is less than or equal to the output rating
on the sensor label
