CEP 6507GU/G, 6508GU/G
Temporary branch power distribution unit
with Ground Fault Protection for personnel
Installation and Operating Instructions
SPECIFICATION
These installation and operation instructions
apply to the following temporary power
branch distribution system components. Do
not discard these instructions, save for future
reference.
PORATBLE POWER
DISTRIBUTION UNITS
These units are rated either 30 or 50 amps,
125/250 VAC, Single Phase. The max. ampacity
for the 30 amp unit is 60A @ 120V, and the 50
amp unit is 80A @ 120V. The 20 amp, 120 volt
outlets are individually protected by circuit
breakers and GFCI circuit modules.

INTRODUCTION
CEP temporary power distribution units are
equipped with GFCI modules to provide
protection from electrocution 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 CEP temporary
power distribution units significantly minimizes
shock hazards. CEP temporary power
distribution units,
which are UL listed as Class A, Group I
interrupters, respond to fault currents as low as
3-6 milliamperes, and will shut off the current
within 1/40
th
of a second. The temporary power
distribution unit is designed to provide protection
against electrical shock hazards due to line-to-
ground faults. Although the GFCI module does
not eliminate the hazard of a shock, it does limit
the duration of the shock to a period considered
safe for normally healthy persons.
GFCI 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 electrical circuit.
ELECTRICITY IS DANGEROUS.
EVEN WHEN SAFETY DEVICES ARE
PRESENT, HANDLE WITH CARE AND USE
REASONABLE CAUTION.
LET CAUTION PREVAIL
The CEP temporary power distribution unit 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 Electric Code, Article
240, must be used on the supply circuit feeding
the temporary power distribution units.
