HUBBELL SPIDER
®
II
Temporary branch power distribution unit
with ground fault protection for personnel
SPECIFICATION
These installation and operating instructions
apply to the following SPIDER II temporary
power branch distribution system
components. Do not discard these
instructions, save for future reference.
PORTABLE SPIDER II POWER
DISTRIBUTION UNITS
All units are rated 30 amps, 125/250VAC,
Single Phase, 5 milliampere leakage current
trip level. Downstream protection is not
provided through the 30 amp outlet. The
seven 20 amp, 120 volt outlets are individually
protected by circuit breakers and GFCI circuit
modules.
INTRODUCTION
Hubbell SPIDER II units equipped with Circuit
Guard
®
GFCI products, will protect you from
shock hazards resulting from ground faults.
Ground faults are current leaks and can result
in electric shock. Currents of only 60/1000 of
an ampere can be fatal. The GFCI protection
provided by Hubbell SPIDER II units
significantly minimizes shock hazards. Hubbell
SPIDER II products, which are listed by
Underwriters Laboratories as Class A, Group
I interrupters, respond to fault currents as low
as 5 milliamperes, and will shut off the current
within 1/40
th
of a second.
The SPIDER II provides ground fault protection
only for circuits to which it supplies power. The
SPIDER II does not protect its power supply
circuit or any circuits which are not supplied
from the Spider unit.
The SPIDER II is designed to provide
protection against electrical shock hazards
due to line-to-ground faults. Although the
Circuit Guard Module does not limit the
magnitude of the fault current, and therefore
cannot prevent electric shock, it does limit the
duration of the shock to a period considered
safe for normally healthy persons.
Circuit Guard Modules will provide protection
against ground faults only. They will not protect
against overloads or short circuits. There is no
known device that will guard against the
electrical shock hazard resulting from contact
with both the “hot” and neutral wires of the
electric circuit.
ELECTRICITY IS DANGEROUS.
EVEN WHEN SAFETY DEVICES ARE PRESENT,
HANDLE WITH CARE AND USE REASONABLE
CAUTION.
LET CAUTION PREVAIL
The Hubbell SPIDER II is designed to be used on
a grounded electrical supply system. It will not
operate when supplied from a power source
which is not grounded. Over-current protection
of the proper rating, according to the National
Electrical Code, Article 240, must be used on
the supply circuit feeding the SPIDER II.
TEST PROCEDURE
All Models
Connect the SPIDER II unit to an appropriate
power source.
CAUTION
• Power is immediately available at the 30
amp Feed thru outlet when the source
is energized on all SPIDER II models.
• Power is immediately available at the 30
amp outlet when the source is energized,
if the respective branch circuit breaker
on the side of the SPIDER II unit is in the
“ON” position.
1. Verify all circuit breakers are in the “on”
