Multiplier for 60 degree bend

Trigonometry, is a branch of mathematics specifically dealing with the sides and angles of triangles. Trigonometry is a key part of conduit bending. Fortunately every type of bend is based off of a right triangle. There's three basic formulas for trigonometry. The values of these formulas play a huge role in determining the unknown sides and angles of a triangle. Typically when bending conduit you decide the theta, and the hypotenuse distance between bends is the unknown value. This is the most common method to conduit bending. While the cosecant method isn't incorrect the accuracy may vary when it comes to larger sized conduits, shoe radiuses, and bends. A multiplier is a value created by taking the reciprocal of the sine from theta and then multiply that value by the opposite. The multiplier is usually simplified by set degree marks that are common bends.

I hope someone can fill me in. Would I just mark the pipe at 17" and put it at the front of the shoe and bend it till it reaches 30 degrees? A total of degrees between openings, regardless of distance, is the NEC's limitation.

Master conduit bending techniques, , and calculations with our comprehensive cheat sheet. Learn the basics, types of conduits, tools required, and for efficient and accurate bending. Conduits are typically made of materials such as metal or plastic and come in various sizes. Here are a few common types of conduits:. These tools are designed to help you achieve accurate bends and ensure the safety of the installation. Here are some of the key tools required for conduit bending:.

Chapman Electric Supply, Inc. Bending conduit can be frustrating without the proper materials. But by using a pipe and conduit bender , even the most problematic angles can be made simple; plus you eliminate the need for costly conduit elbows when you make your own bends. When you use a bender with indicators and degree markers - like this one from Klein Tools - making a 30, 60, or 90 degree bend is simple. When making off-set, back-to-back, stub-ups or saddle bends, using a bender with a degree scale and multiplier scale helps save you time and energy. An Offset conduit bend is kind of bend that changes the direction of the conduit at an angle, while keeping a consistent distance to a wall, ceiling or other surface. Basically, it allows you to run your conduit around an obstacle that is in the conduit path.

The values of these formulas play a huge role in determining the unknown sides and angles of a triangle. When bending a 12 inch offset using a 30 degree bend what would the distance between the two bends? MiamiValleyelec said:. A inch beam is in the path of a conduit run from a junction box which is located 38 inches from the beam The beam is to be bypassed by a degree offset with the second offset bend occurring at t? What is the offset when using a conduit bender? Status Not open for further replies. Study now See answers 2. What is the total shrinkage of a set of 30 degree offset bends with a depth of 7 in and a set of 22 12 degree opffset bends with a 4 in depth? That way it doesn't matter which size pipe you are using, the multiplier is still going to be two. Tulsa Electrician Senior Member. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized. When using a 3 point saddle over smaller conduits, I often make my center bend at 30 degrees and estimate my outer bends at 15 degrees. Where in CA are you?

The values of these formulas play a huge role in determining the unknown sides and angles of a triangle. Sinceconduit bends are curved and not exact angles this may not be accurateenough to pre-cut and thread and then bend. The shrink constant is determined by taking the tangent and of the theta Bend by 2. Edit this page. Sort by Oldest first Oldest first Newest first Most reactions.
