listen
a straight pull box is to be used in a 4 - inch conduit run that will carry no. 2 cables. the pull box must have a minimum length of
a) 6 inches.
b) 16 inches.
c) 32 inches.
d) 36 inches.

Explanation:

Step1: Recall the code requirement

For a straight pull box with cables in conduit, the minimum length of the pull box is 8 times the trade size of the conduit.

Step2: Calculate the length

Given the trade size of the conduit is 4 - inch. Using the formula \(L = 8\times d\) (where \(d\) is the trade - size of the conduit), we substitute \(d = 4\) into the formula. So \(L=8\times4 = 32\) inches.

Answer:

C. 32 inches
