Sample questions
Which two tests does an assured equipment grounding conductor program require on cord sets and cord-and-plug equipment?
Grounding conductor continuity and its connection to the proper terminal
Insulation resistance of each conductor and voltage drop at full load
Trip time of the breaker and trip current of the breaker
Polarity of the receptacle and resistance of the ground rod
Show the answer
A. Grounding conductor continuity and its connection to the proper terminal
The program requires a continuity test of the equipment grounding conductor and a test that the conductor is connected to its proper terminal. Insulation resistance and voltage drop are useful checks but are not the tests the rule calls for.

A trench is 4 feet deep in soil that is not stable rock. When may workers enter it with no protective system?
When a competent person examines the ground and finds no indication of a potential cave-in
When the foreman decides the work will take less than 30 minutes to complete
When each worker in the trench wears a harness with a lifeline to the surface
When the spoil pile is placed at least 5 feet back from the edge of the trench
Show the answer
A. When a competent person examines the ground and finds no indication of a potential cave-in
Excavations less than 5 feet deep need no protective system only if a competent person has examined the ground and found no indication of a potential cave-in. How short the job is makes no difference; shallow trenches still kill.

A deceleration device in a personal fall arrest system may bring the worker to a stop over no more than what distance?
1.5 feet
2 feet
3.5 feet
6 feet
Show the answer
C. 3.5 feet
Deceleration distance is limited to 3.5 feet. Six feet is the free fall limit, which is measured before the device begins to work, so the two are easy to mix up.
