License Exam Quiz #384

de Steve, AE8AT 

The quiz began at a Thursday Night Group on August 16, 2018. The quiz has turned 8 years old! Since the question pools are short on questions regarding birthdays, candle safety, or anniversaies, the quiz will instead focus on lightning since the storms this past week frequently intruded on our sleep.

A. Put a drip loop in the ground connection to prevent water damage to the ground system
B. Make sure all ground wire bends are right angles
C. Ensure that connections are short and direct
D. All these choices are correct

G0B11 Which of the following is required for lightning protection ground rods?
A. They must be bonded to all buried water and gas lines
B. Bends in ground wires must be made as close as possible to a right angle
C. Lightning grounds must be connected to all ungrounded wiring
D. They must be bonded together with all other grounds

E4E14 What is the purpose of a single point ground panel?
A. Remove AC power in case of a short-circuit
B. Prevent common-mode transients in multi-wire systems
C. Eliminate air gaps between protected and non-protected circuits
D. Ensure all lightning protectors activate at the same time


Answers:
T0B01 = C
G0B11 = D
E4E14 = D
