Question 4
When installing PVC conduit outdoors exposed to sunlight, what additional factor should the electrician consider?
Question 5
An apprentice is asked to install EMT (electrical metallic tubing) along a wall with several offsets. What is the main reason for using a hand bender rather than multiple couplings and elbows?
Question 6
Which of the following best describes the function of a fish tape?
Question 7
A conduit run requires several bends to avoid obstacles. What is a key consideration to maintain compliance and ease of pulling conductors?
Question 8
Why is it important not to overfill a conduit with conductors?
Question 9
When making a simple offset in EMT to reach a knockout that is 50 mm above the original conduit run, which practice helps ensure the offset is accurate?
Question 10
When bending electrical metallic tubing (EMT) for a 90-degree stub-up, why is it important to account for the manufacturer's take-up value on the bender?
Question 11
What is the approximate 'take-up' for a 90-degree bend using a standard hand bender for 3/4-inch EMT?
Question 12
An electrician is installing a 90-degree bend in 3/4" EMT using a standard hand bender. What is the typical 'take-up' for this size conduit?
Question 13
When pulling conductors into conduit, what is the primary reason for using wire-pulling lubricant?
Question 14
When installing conductors in conduit, which limitation is most important to respect to avoid overheating and damage?
Question 15
When bending a 1 in EMT conduit to make a simple 30-degree offset around an obstacle, what is one important consideration?
Question 16
When bending electrical metallic tubing with a hand bender for a 90 degree stub-up, what should the apprentice do to maintain the correct finished height?
Question 17
When installing EMT (electrical metallic tubing) in an exposed basement ceiling, which tool is commonly used to create offsets and bends?
Question 18
A conduit run requires a 30° bend followed by another 30° bend to clear an obstruction. What is the total angle of bend for this offset?
Question 19
When making a 90-degree bend in electrical metallic tubing (EMT) with a hand bender, what is the BEST practice?
Question 20
When bending 3/4 inch EMT for a 90-degree stub-up, what information is most important to avoid making the bend too short or too long?
Question 21
When using a hand bender to make a stub-up 90° bend in EMT, why is it important to use the take-up mark indicated on the bender?
Question 22
A journeyperson is installing EMT in a commercial space. They need to make a 90-degree bend with a hand bender. To maintain proper bend quality, what should they do?
Question 23
What is the minimum bending radius for a run of $2$-inch Rigid PVC Conduit (Schedule 40) using a single $90$-degree bend, according to NEC Chapter 9, Table 2?
Question 24
When bending 1/2" EMT, what is the standard take-up for a 90-degree stub-up using a hand bender?
Question 25
What is the maximum total degrees of bends permitted in a conduit run between pull points?
Question 26
What is the maximum total degree of bends permitted in a single run of conduit between pull points?
Question 27
When bending 1/2" EMT, what is the standard 'take-up' or 'stub-up' deduction for a 90° bend using a standard hand bender?
Question 28
A 100 ft run of 1/2" EMT has three 90 degree bends. You need to add another 90 degree bend to reach the box. What must you do?
Question 29
Which type of conduit bend is used to bypass a small obstruction on a wall while maintaining the conduit's original path line?
Question 30
A 100-foot run of 1/2-inch EMT requires two 90-degree bends and two 45-degree offsets. What is the total degrees of bend in this run?
