1. The National Electrical Code (NEC) is primarily considered:
A. A federal law
B. A state statute
C. A local ordinance
D. A model code
The NEC is a model code published by NFPA and adopted by
jurisdictions, not law itself.
2. What is the minimum number of branch circuits required for
dwelling unit small-appliance circuits?
A. 1
B. 2
C. 3
D. 4
NEC requires at least two 20-amp small-appliance branch circuits in
kitchens.
,3. Copper conductors are preferred over aluminum because they:
A. Are cheaper
B. Have higher resistance
C. Have lower resistance and better conductivity
D. Are lighter
Copper provides better conductivity and lower voltage drop.
4. The color of a grounded neutral conductor is typically:
A. Green
B. Red
C. Black
D. White or gray
NEC requires white or gray for grounded conductors.
5. What is the standard frequency of electrical power in the U.S.?
A. 50 Hz
B. 60 Hz
C. 120 Hz
D. 60 Hz
U.S. electrical systems operate at 60 Hz.
6. Which device protects against overcurrent?
A. Switch
B. Receptacle
C. Circuit breaker
D. Transformer
, Breakers open the circuit under overload or short circuit.
7. The purpose of grounding is to:
A. Increase voltage
B. Provide a fault current path to earth
C. Reduce resistance
D. Store electricity
Grounding ensures safety by directing fault current safely.
8. Ohm’s Law states:
A. V = I + R
B. I = V × R
C. V = I × R
D. R = V × I
Ohm’s Law defines voltage as current times resistance.
9. A 20-amp circuit at 120V can supply:
A. 1200W
B. 2400W
C. 3600W
D. 4800W
P = V × I = 120 × 20 = 2400 watts.
10. What color is typically used for equipment grounding
conductors?
A. White
B. Black
