CEP 6506GU, 6506G
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
All units are rated 50 amps, 125/250 VAC,
Single Phase, 5 milliampere leakage current
trip level. Downstream protection is not provided
through the 50 amp outlet. The 20 amp, 120 volt
outlets are individually
protected by circuit breakers and GFCI
circuit modules.

INTRODUCTION
CEP temporary power distribution units equipped
with GFCI products will protect you 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 of 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.
TEST PROCUDURE
All Models
Connect the temporary power distribution unit to
an appropriate power source.
CAUTION
Power is immediately available at the 50
amp outlet when the source is energized
on all models.
1. Verify all circuit breakers are in the “on”
position.
