1. What is the minimum category rating for a meter used with a distribution
panel?
CAT 3
CAT 1
CAT 4
CAT 2
2. What is an employee responsibility with regard to the use of PPE?
To inspect your PPE prior to each use
To modify poor fitting PPE so it fits properly
To wear your PPE only when you sense an accident may happen
To inspect your PPE once a month
3. In an arc flash risk assessment, the presumed working distance for low-
voltage MCCs and panels is _ _.
24"
6"
18"
12"
4. If a worker is performing maintenance on an MCC that has been locked
out, what safety measures should still be considered?
,The worker should only check for voltage before starting work.
The worker can assume there is no risk and proceed without
, precautions.
The worker can work without PPE since the MCC is locked out.
The worker should still wear appropriate PPE and assess arc
flash risks.
5. Describe the significance of the presumed working distance in an arc
flash risk assessment.
The presumed working distance is irrelevant to the assessment of
electrical hazards.
The presumed working distance is used to calculate the cost of
safety equipment.
The presumed working distance is critical as it helps determine
the potential arc flash hazard and the necessary protective
measures.
The presumed working distance only applies to high voltage
systems.
6. What is the presumed working distance for low voltage MCC's and
panels in an arc flash risk assessment?
18 inches
30 inches
24 inches
12 inches
7. Live parts to which an employee may be exposed shall be de-energized
before the employee works on or near them unless it is infeasible (Such
as Troubleshooting and Testing) and ___.
there is a short maintenance window.
the equipment is mission critical
