INTRODUCTION
CEP temporary power distribution units equipped
with GFCI modules that 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.
