Chapter 4, Problem 1R
The largest size solid conductor generally permitted to be installed in a raceway is (10 AWG) (8 AWG) (6 AWG). (Circle the correct answer.)
Expert Solution & Answer
To determine
Choose the correct answer for the largest size solid conductor that is permitted to be installed in a raceway.
Answer to Problem 1R
The correct answer for the largest size solid conductor that is permitted to be installed in a raceway is 10 AWG.
Explanation of Solution
Description:
According to the American Wire Gauge (AWG) standards, the copper and aluminium wires used in electrical installations are graded for specific size. A tube that is used to protect and route electrical wiring is called as electrical conduit. A closed conduit that forms a physical path for electrical wiring is called as a raceway.
Due to the flexibility and ease of handling and pulling, 10 AWG conductors are used in a raceway.
Conclusion:
Thus, the correct answer for the largest size solid conductor that is permitted to be installed in a raceway is 10 AWG.
