NFPA 70E level 1
false
Working on energized circuits is part of the job and should be considered a routine part of the
electrical work that an Electrical Worker performs.
1 and 4
Contractors and their clients are exposed to undue risks of increased insurance premiums and
loss of production.
&
Workers expose themselves to potential injury or death.
Which of the following are likely outcomes when energized work is performed when it is not
justified?
I. Contractors and their clients are exposed to undue risks of increased insurance premiums and
loss of production.
II. Contractors and their clients are in compliance with OSHA requirements.
III. Workers expose themselves to few or no hazards.
IV. Workers expose themselves to potential injury or death.
true
The faster an arcing fault is cleared by the overcurrent protective device, the lower the amount
of energy released.
I. and III.
Extensive tests and analysis by industry members have shown that the energy released during
an arcing fault is related primarily to two characteristics of the OCPD protecting the affected
circuit:
I. The amount of fault current the OCPD lets through
II. The ampacity of the OCPD
III. The time it takes the OCPD to open
IV. The voltage rating of the OCPD
false
During an arcing fault event, the thermal energy released is not directly proportional to the time
it takes to interrupt the fault current.
