Question 18

Next, the conduit is inserted into the bender and the mark is aligned with the front of the shoe as shown. Keep in mind that in order for the bender chart to be usable by all of the electricians on the job, there must be agreement as to where Mark 1 is to be aligned relative to the collar or hook. In this case, the mark is aligned with the flat front surface of the rotating part of the bender, thereby enabling a worker to sight down the front of the shoe from above, and then adjust the position of the mark until it is just visible at the front of the shoe. Another thing to consider is that the bender may be able to handle multiple conduit sizes

and types, and it may not be practical to chart the bender for all of the possible combinations at the same time.

A mark is being made 10" from the back of the conduit support. What is the designation for this mark?

a. Mark 1

b. Mark 2

c. Mark 3

d. Mark 4
