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.
The EGF Series with mechanical outputs are
available in solid-core housings with a choice
of Normally Energized or Normally De-Energized SPDT relays. All
mechanical models can be ordered with a fixed setpoint or with a
“tri-set” option, which provides three factory-set, field adjustable
setpoints.
ote:N This manual only covers EGF Series models with SPDT relays (listed
in the table on page 1). For installation manuals covering other models in the
EGF Series family, please contact Eaton’s 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 fit.
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,
b. CAUTION: The output and any connected loads will
switch during the test process.
Installation
Considerations for all 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
flows in the same direction (see “Principal of Operation” section
on this page).
•
These sensors can be located in the same environment as
motors, contactors, heaters, pull-boxes, and other electrical enclo-
sures.
•
Mounting can be done in any position or hung directly on a wire
with a wire tie.
•
Be sure to leave at least one in. (25.4 mm) distance between sen-
sor and other magnetic devices.
•
Connect power and output wiring using up to 14 AWG copper
wire and tightening terminals to 4.5 in.-lbs / 0.51 N·m maximum
torque.
Principle of Operation
Under normal conditions, the current in one wire of a two wire load
is equal in strength but opposite in sign to the current in other wire.
The two wires create magnetic fields that cancel, a condition known
as “Zero Sum Current.” If any current leaks to ground (Ground Fault),
the two currents become unbalances and there is a net resulting
magnetic field. The EGF Series sensor detects this minute field and
change the output state. This concept extends to 3- phase systems
such as 3-wire Delta and to 4-wire Wye.

Wiring
Run all current carrying conductors through the sensor aperture in
the same direction. Connect power wiring to the sensor. Be sure
the power supply matches the power rating on the sensor label. Use
up to 14 AWG copper wire and tighten terminals to 4.5 in.-lbs / 0.51
N·m maximum torque. Connect output wiring to the sensor. Be sure
that the output load is less than or equal to the output rating on the
sensor label. Use up to 14 AWG copper wire and tighten terminals
to 4.5 in.-lbs / 0.51 N·m maximum torque.

Operation
To test operation, gently press the TEST button. This simulates a
fault and tests the internal switching circuits. The following operation
should be observed.

Setpoint Adjustment
The EGF Series sensors are factory calibrated to trip at the setpoint
specified by the model number. While it is generally recommended
not to change this setpoint, it can be done by following the below
steps.
1. Connect control power and circuits. Run a conductor through the
aperture with current equal to your desired setpoint.
2. Adjust setpoint to maximum by first removing the setpoint cover.
Turn the adjustment pot five revolutions counter-clockwise to the
maximum (least sensitive) setpoint. The Status LED should be
off. The adjustment pot has a slip clutch so that you cannot feel
or damage the end point.
3. Dial in the new setpoint by slowly turning the pot clockwise until
the LED turns on. The sensor is now adjusted to trip at the cur-
rent that is passing through the aperture. Reset the sensor.
4. Relabel the sensor with a new setpoint. Use a label maker or
tape with a permanent marker.
Power Supply Notes
All low-current ground-fault sensors are sensitive devices that
require reasonable care in system design to avoid false trips caused
by high electrical noise levels. Keep in mind that the best way to
reduce noise in a system is to suppress it at its source.
•
Keep the sensor power isolated from noisy circuits.
•
Do not power the sensor with the same circuit that switches con-
tactors or other high current inductive loads.
System Grounding
Good design practice and code require that all AC power systems
be grounded. The EGF Series sensors are designed to work on
grounded AC power systems. They may not operate properly on
ungrounded systems.
