A feeder termination has no torque record, and the installer used an adjustable wrench by feel. What should be required before acceptance?
Correct Answer
A) Verify the termination with a calibrated torque tool to the manufacturer's value
Electrical terminations need to be made to the manufacturer's specified torque using proper tools when torque is specified. Other choices rely on feel or conceal a connection that may be loose or overtightened.
Why This Is the Correct Answer
Electrical terminations need to be made to the manufacturer's specified torque using proper tools when torque is specified. Other choices rely on feel or conceal a connection that may be loose or overtightened.
Why the Other Options Are Wrong
Option B: The installer should accept the work if the conductor cannot be pulled out by hand
A hand pull only shows the conductor did not slip loose; it does not prove the lug was tightened to the manufacturer's torque value.
Option C: Loosen and retighten the lug without checking the listed value
Loosening and retightening without the listed value repeats the same uncontrolled workmanship problem.
Option D: Cover the termination with tape to prevent movement
Tape can conceal a termination but cannot correct an undertightened or overtightened lug.
Memory Technique
Tag the scene with terminal torque verification: wrong actor or wrong timing means the fix is not Verify the termination with a calibrated torque tool to the manufacturer's value.
