Question

whats the ampacity of a no. 3/0, thhn copper wire in a conduit with one other conductor?
a) 225 a
b) 350 a
c) 175 a
d) 200 a
question 6 (5 points)
which type of tape is used to round sharp edges on splices using larger conductors?
a) plastic tape
b) friction tape
c) rubber tape

Explanation:

For the first question, according to electrical wiring standards (such as NEC - National Electrical Code), the ampacity of a No. 3/0 THHN copper wire in a conduit with two conductors (as one other conductor means total two) is 200 A.
For the second question, friction tape is used to round sharp edges on splices with larger conductors. It provides a smooth surface and helps in insulation and protection.

Answer:

First question: D. 200 A
Second question: B. Friction tape
