NEVADA C-2D LOW VOLTAGE EXAMINATION
TEST 2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉ What is the "Limited Approach Boundary" for low voltage
equipment? Answer: 4' from fixed exposed and potentially energized
conductors.
10' from movable exposed and potentially energized conductors.
◉ What is the "Flash Protection Boundary" for low voltage
equipment? Answer: 4' or follow the Flash Hazard Label on the
equipment.
◉ What is the "Restricted Approach Boundary" for low voltage
equipment? Answer: 1' from exposed and potentially energized
conductors.
◉ What must happen for an individual to cross the Flash Hazard
Boundary? Answer: Must have flash protection on and be L.V.
qualified.
◉ What must happen for an individual to cross the Limited
Approach Boundary? Answer: Must be qualified or be under the
direct supervision of a qualified person.
,The E&I techs that open the panel/enclosure must maintain this
distance (ensure unqualified folks do not enter).
◉ What must happen for an individual to cross the Restricted
Approach Boundary? Answer: Must have Shock Protection.
◉ What are the 3 hazards of electricity? Answer: Shock - Current
flowing through your body
Arc Flash - Release of electrical energy through the air producing
extreme HEAT and light
Arc Blast - Rapid expansion of gasses, circuit parts, molten metal, etc.
creating an over pressure situation similar to an explosion.
◉ What PPE is required when checking fuses in an MCC bucket?
How do you determine this? Answer: Flash & Shock protection to
verify power,
If the MCC has a Flash Hazard Label then follow the category PPE on
the label,
if it does not then you must follow the "Table Method" in PCP-650 or
NFPA-70E.
◉ What are the different levels of Electrical Qualifications and the
voltage level associated with each one? Answer: "General
Awareness" - for all employees (BEST training)
, "Task Qualification" - for a specific task.
"Low Voltage" (LV) - 50 to 1,000 v
"Medium Voltage (MV) - 1,000 to 36,000 v
"High Voltage (HV) - 36,000 volts & up
◉ Explain every step you would take to verify a circuit is de-
energized that feeds a 3 phase motor. Answer: *Turn off the
equipment (load)
*ID flash protection and wear
*Turn off / open disconnect device
*LOTO
*Wear shock protection
*Check your meter on a known live source
*Check your circuit - phase to phase and phase to ground
*Check your meter again
◉ When do you need Flash Protection? Answer: When within the
Flash Protection Boundary or when interacting with the equipment
in a way that could cause an electrical arc (voltage testing, trouble
shooting, commissioning new equipment, operating an ACB, MV
disconnects, after maintenance, - anything that is not normal
operating conditions).
