Question 1
When sizing a pull box for a straight pull with 3-inch conduit, what is the minimum length of the box?
Question 2
When sizing a pull box for a straight pull with 3-inch conduit, what is the minimum length?
Question 3
What is the maximum allowed number of quarter bends (90-degree equivalents) between any two pull points in a conduit run?
Question 4
What is the maximum number of 90-degree bends allowed in a single conduit run between pull points (boxes or fittings)?
Question 5
A conduit run has four 90-degree bends between pull points. What installation concern does this raise?
Question 6
When laying out a conduit run with multiple bends, why is it important not to exceed the maximum total degrees of bend between pull points?
Question 7
You are installing EMT (electrical metallic tubing) in a commercial space. What is the maximum number of quarter bends (90° total) allowed between pull points according to typical code practice?
Question 8
What is the purpose of a junction box in an electrical installation?
Question 9
You need to pull several THHN conductors through a long run of EMT. Which tool is most appropriate to assist with this task?
Question 10
While reviewing a conduit layout, you notice a proposed run of EMT with five 90-degree bends between pull points. What is the best recommendation?
Question 11
When bending $1/2\text{-inch}$ Electrical Metallic Tubing (EMT) using a hand bender, what is the maximum number of degrees of bend allowed between two pull points (outlet, junction, or terminal box)?
Question 12
What is the primary factor that determines the minimum depth of a pull box containing conductors of $4 \text{ AWG}$ or larger, where the conductors enter the box through straight pulls?
Question 13
What is the primary purpose of a fish tape when running branch-circuit wiring?
Question 14
When sizing a pull box for a straight pull involving 4-inch conduit, what is the minimum length required by NEC Article 314 concepts?
Question 15
