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.
TROUBLESHOOTING THE SPIDER II
The main power contactor within the SPIDER II
unit will trip whenever one or more of the
following abnormal conditions exist in the line
(supply) side circuit:
1. Any line (hot) conductor is transposed with
the neutral conductor.
2. Any line (hot) conductor is or neutral
conductor 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 GFCI test procedure be repeated at this
time.
When a GFCI 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 GFCI 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 branch circuit breaker in
the 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 turning handle to "OFF" position
and then to the "ON" position.
APPLICATION NOTES
1. Tripping of individual branch circuit breakers
in any SPIDER II unit has no effect on
downstream units connected through the
60 amp outlet.
2. There is no overload protection for the 60
amp outlet.
3. When shutting down the temporary power
at the end of the working day, do so by
pressing the test button on the individual
modules on the SPIDER II unit.
NUISANCE TRIPPING
All cables have some capacitive leakage. In a
120 V system, there is a limit to the length of
cable which can be run before sufficient
leakage to ground will build up causing a GFI
to trip. In the Hubbell SPIDER II system,
however, capacative leakage in the two power
lines flows in opposite directions. This design
cancels the capacative leakage effect, and
there is no theoretical limit to the length of
interconnecting cable runs between SPIDER
II units. Individual 120 volt branch circuit load
cords, however, should be limited to 250 feet
in length.
MAINTENANCE & REPAIR
CAUTION: Electrical power supply MUST BE
OFF AND DISCONNECTED before and during
any repair or maintenance. Repair and
maintenance must be performed by a trained
and competent electrician.
WARNING: If any parts or components of
Spider II unit appear to be missing, broken or
show signs of damage, DISCONTINUE USE
IMMEDIATELY! Do not modify these devices
in any way. Replace worn or damaged
components. Failure to do so could cause
serious personal injury and/or equipment
damage.
