What is the standard take-up (deduct) for making a 90-degree bend in 1/2" EMT conduit?
Answer: 5 inches
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.
To bend a 45-degree offset with a rise of 6 inches, what is the distance between the two bend marks?
Answer: 8.48 inches
Distance = 6 x 1.414 (the multiplier for 45-degree bends) = 8.48 inches between the two marks.
Which multiplier is applied to the offset height when bending a 30-degree offset?
Answer: 2.000
A 30-degree offset uses a multiplier of 2.000 because 1 divided by sin(30 degrees) = 1 divided by 0.5 = 2.000.
What is the standard take-up for a 90-degree bend in 3/4" EMT?
Answer: 6 inches
The standard take-up for 3/4" EMT is 6 inches for a 90-degree stub-up bend.
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?
Answer: 6 inches
Mark location = desired stub height minus take-up = 14 minus 8 = 6 inches from the end of the conduit.
Per the NEC, what is the maximum total degrees of bends permitted in conduit between pull points?
Answer: 360 degrees
NEC Sections 358.26, 344.26, and similar articles limit total bends to 360 degrees (equivalent of four 90-degree bends) between pull points.
Which NEC article governs the installation of Rigid Metal Conduit (RMC)?
Answer: Article 344
NEC Article 344 covers Rigid Metal Conduit (RMC) installation requirements.
