2. Push the test button on the individual GFCI
module. The unit should trip.
3. Push the reset button. The indicator light
should come on.
4. Repeat steps 2 & 3 for the remaining five
modules.
TROUBLE SHOOTING
The GFCI Modules within the temporary power
distribution unit will trip whenever one or more of
the following abnormal conditions exist in the line
(supply) side circuit:
1. Either line (hot) conductor is transposed with
the neutral conductor.
2. Either line (hot) conductor is open
(disconnected)
3. There is an excessive voltage imbalance
between line 1 and line 2 circuits. This may be
the result of an open neutral conductor in the
supply circuit.
When the abnormal condition(s) in the supply
circuit is corrected, the unit may be reset for
normal use by completely removing and then
reapplying line power. It is recommended that
the GFI test procedure be repeated at this time.
When a GFI module trips, attempt to reset it by
pressing the reset switch, being careful to look
for possible danger to personnel. If the module
resets, the fault was momentary and has
cleared. If it trips again immediately, the fault is
still present and the GFI module is performing its
safety function. To locate the fault, disconnect all
loads and again try pressing the reset switch.
The module should reset. Reconnect the loads
one at a time. The module will trip when the
faulted load is reconnected. Inspect all tools,
appliances and extension cords in the faulted
load circuit, repairing or replacing any that are
not in good condition.
NOTE: Tripping of a circuit breaker in these
models can only result from an overload or short
circuit condition in its individual load circuit.
When the fault in the load circuit is corrected or
removed, the circuit breaker can be reset for
normal use by switching handle to “OFF” position
and then to the “ON” position.
APPLICATION NOTES
1. Tripping of individual branch circuit breakers in
any temporary power distribution unit have no
effect on downstream units connected through
the 50 amp outlet.
2. There is no overload protection for the 50 amp
outlet.
NUISANCE TRIPPING
All cables have some capacitive leakage. In a
120 volt system, there is a limited to the length of
cable which can be run before sufficient leakage
to ground will build up causing a GFI to trip.
Individual 120 volt branch circuit load cords
should be limited to 250 feet in length.
HIGH VOLTAGE LIGHT
Indicates the input wiring is incorrect, and to
check the power source,
CONTACT MONITOR LIGHT
The red monitor light is a welded contact
indicator, that is, if the monitor light is on with the
unit tripped, it indicates the contact is welded,
and the unit should be replaced immediately --
there is no GFCI protection. (When the TEST
button is pressed, both the POWER light and
MONITOR light should go out, and come back
on when the RESET button is pressed.
