2.4 Ground Connections
Connect the supply and load ground conductors to the
chassis bonding point ( ) as shown in Fig. 3. Use a flat-
blade screwdriver to tighten the ground connections.
Torque the ground terminals as described in Section 7.
The ground terminals will accept 14 to 1/0 AWG (2.08 to
53.5 mm
2
) conductors.
2.5 Load-Ground-Connection Monitor
An insulated pilot wire from the SB6100 to the load,
and a termination device located at the load are required
to monitor the load-ground connection. Total pilot wire
and ground wire resistance must be less than 38 ohms.
Outline dimensions and mounting details for compatible
termination devices are shown in Figs. 9, 10, and 11.
This monitoring function is required for Class C and
Class D GFCI models installed in NEC applications, and
can be implemented if desired for Class A GFCI or
EGFPD models.
Use only a Littelfuse termination device as others may
not meet performance requirements. Each SB6100 GFCI
is supplied with a 1N5339B termination device. Install
the termination device at the load to complete the ground-
connection loop as shown in Fig. 2. Connect terminal G
of the termination device to the equipment frame so that
the ground-conductor-to-equipment-frame connection
will be included in the monitored loop. Connect terminal
GC to the pilot wire and connect the pilot wire to the
SB6100 terminal GC as shown in Figs. 2 and 3.
EGFPD models include a 1N5339B termination device
installed at the GC terminal. The termination device
should remain installed at the GC terminal if the load-
ground-connection monitoring feature is not required.
2.6 Auxiliary Contactor Terminals
An auxiliary normally-open contact (labeled AUX) is
provided on all models. This contact, rated at 4 A,
240 Vac, follows the state of the internal contactor. See
Figs. 2 and 3.
