Question 1

What is the standard take-up (deduct) for making a 90-degree bend in 1/2" EMT conduit?

Accepted Answer

5 inches

Answer

The standard take-up for 1/2" EMT is 5 inches; subtract this from the desired stub height to locate the bend mark on the conduit.

Question 2

To bend a 45-degree offset with a rise of 6 inches, what is the distance between the two bend marks?

Accepted Answer

8.48 inches

Answer

Distance = 6 x 1.414 (the multiplier for 45-degree bends) = 8.48 inches between the two marks.

Question 3

Which multiplier is applied to the offset height when bending a 30-degree offset?

Accepted Answer

2.000

Answer

A 30-degree offset uses a multiplier of 2.000 because 1 divided by sin(30 degrees) = 1 divided by 0.5 = 2.000.

Question 4

What is the standard take-up for a 90-degree bend in 3/4" EMT?

Accepted Answer

6 inches

Answer

The standard take-up for 3/4" EMT is 6 inches for a 90-degree stub-up bend.

Question 5

You need a 90-degree stub-up of 14 inches in 1" EMT (take-up = 8 inches). Where should the bend mark be placed from the end of the conduit?

Accepted Answer

6 inches

Answer

Mark location = desired stub height minus take-up = 14 minus 8 = 6 inches from the end of the conduit.
