Which of the following parameters does not play a role in the severity of current passing
through the human body? - ANSWER An outdoors application
Which of the following best describes the primary purpose of overcurrent protective devices
(OCDs) concerning arc-flash and arc-blast hazards? - ANSWER To reduce severity of arc-
flash events
Energized electrical conductors and circuit parts operating at voltages equal to or greater
than ? shall be put into an electrically safe work condition before an employee performs

Which of the following is the electrical shock voltage threshold? - ANSWER 50 VAC / 50
VDC
In the context of incident energy, why is regular maintenance of electrical systems essential?
- ANSWER To minimize the risk of arc flash events and associated injuries
An are energy reduction system impacts safety through which of the following? -
ANSWER Reduces severity of an arc flash event when turned on and the arcing current is
in the operating region
What role does regular maintenance play in preventing electrical accidents? - ANSWER It
identifies and rectifies potential hazards.

current at the panelboard and supplied from a current-limiting fuse operating in the current-
limiting region? - ANSWER PPE Category 2
Electrical equipment must be maintained in accordance with ? or ? to reduce the risk
associated with failures. - ANSWER "Manufacturer's instructions" / "Industry consensus
standards"
Incident energy is defined as the amount of ? energy impressed on a surface, a certain
distance from the source, generated during an electrical arc event. - ANSWER Thermal
