What is the most basic conduit bend?
The stub bend is made by bending a piece of conduit into an L shape or 90° bend by placing the free end (short end) of the tube to a predetermined length as indicated in the diagram below. This is the most common bend and is a building block for other bends.
How many bends are allowed in conduit?
National Electrical Code or NEC limits the total number of bends in one continuous run to 360 degrees or four 90 degree bends. It specifically states, “There shall not be more than the equivalent of four quarter bends (360 degrees total) between pull points, for example, conduit bodies and boxes.”
How do you measure conduit bends?
Answer: There is no real formula, but it can be calculated with a fair degree of precision. Multiply the radius of the bend you want to make by 6.28, then by degrees, bend and divide by 360. Divide once more by two, measure from the center of the pipe that far then set that mark at the front edge of the bending shoe.
What is setback in conduit bending?
SETBACK = Difference between the take-up and the gain. It is used for finding the stub-up mark from the leg side. by being added to the leg length. KICK = A bend at less than 90º.
What is another name for a 90 degree bend?
Another type of bend is a Miter bend. A Miter bend is a bend that is made by cutting pipe ends at an angle and joining the pipe ends. A true miter bend is a 90-degree bend made by cutting two pipes at 45 degrees and joining them by welding.
How much does it cost to add bending conduit?
The most common deducts are 5″ for ½” conduit, 6″ for ¾” conduit and 8″ for a 1″ bender. It is a function of the curvature radius of the bender and cannot be changed. The deduct for your bender should be stamped on the bender.

What is a comeback in conduit bending?
1. Electrical Workshop: Pipe Bending Vocabulary. Back-To-Back: Two ninety degree bends in one conduit, usually with both stubs turned up on the same plane forming a “U”.
How do you bend parallel kicks in conduit?
Subtract 1/2 the diameter of the conduit. In this case, 1/2″ conduit is about 3/4″ in diameter, so subtract 3/8″. Now subtract a second amount equal to the distance from the center of the bend to your start mark. Place the start mark of your bender on this new mark on the conduit, and make a 10″ kick.
How do you use conduit Bender?
Pull the bender handle toward you to create the bend. Use a firm and steady motion to avoid kinks or crimps in the conduit. Make sure your foot and hand remain securely on the bender; any small slip in the conduit can cause an off-centered bend, and you will need to start over with a new piece of conduit.
What is conduit bending?
Conduit Bending. Conduit bending is one of the first skills learned by new apprentices in a commercial or industrial shop. They learn to use multipliers for 15°, 30° and 45° for offset bends. Most settle in on the 30° bend since the multiplier is 2. It makes the math very easy.
