Question

when using a set - screw type pulling head, the general rule is that the conductor should occupy between? of the barrel connectors cross - sectional area.
a. 20 - 40%
b. 40 - 60%
c. 60 - 80%
d. 80 - 100%

Explanation:

In electrical engineering (a subfield of Engineering under Natural Science), when using a set - screw type pulling head, the standard practice is that the conductor should occupy between 60 - 80% of the barrel connector's cross - sectional area. This range ensures proper mechanical and electrical connection while also considering factors like stress distribution and conductivity.

Answer:

c. 60 - 80%
