## Helpful Formulas for Bending electrical Conduit

Very few beginning electricians space taught anything past the most basic instructions because that bending electric conduit pipe (EMT, electric metallic tubing). As a result, they deserve to have enormous challenge when trying to bend larger conduit (greater than 1”). Even much more experienced journey-level electricians seldom have any idea of the wide variety of possibilities available. Nevertheless, learning exactly how to bending conduit to very nearly any kind of angle you want is not difficult.

The math and also formulas that make up a simple conduit-bending guide are actually quite basic and easily learned. The only tools you require for more facility bends space an angle finder and a cheap scientific-type hand calculator or, in today's world, a smartphone v a calculator.

Any electrician bending large conduit should already have an edge finder together without a hand bender to tell the angle being bent an angle finder is necessary. If girlfriend don't, there are some examples at the finish of this article. And also now that we have actually smartphones, the calculator isn't just cheap; it's free. Recommended because that Android phones is the RealCalc scientific calculator app, obtainable from the Google Play keep at no charge. Simply search the keep for RealCalc and also download it.

## Math used for Bending Conduit

The mathematics of conduit-bending that us will discuss here originates from two sources. Several of the math is already built into a usual hand bender device, and the rest of it requires the geometry that a triangle.

Note that making concentric bends requires using some extr math not disputed in this article.

**Math indigenous Hand Benders**

Deducts, bending radiuses, and multipliers

Lots of mathematics is built into the hand bender device. Only a few numbers and also math operations have to be memorized to do offsets, saddles and 90 level bends. Also the “multiplier” and “deduct” figures are generally stamped ~ above the bender device.
