### What is the deduction for a 2 inch EMT 90?

For a 90 stub up for a 2″ EMT the chart says Minimum stub length = 18-3/8″ and deduction (take up) for the mark #1 is 16-3/8″. The route that the conduits will take is; 50″ straight up to the top of first 90 (out of cabinet) changing from vertical to horizontal plane.

### How do you calculate conduit bend radius?

Elements of a Bend

- Calculating Wall Thickness.
- σs=PN.(da-s/20.s)=PN.S.
- Calculating Standard Dimension Ratio.
- SDR = da/s.
- Calculating CLR (Center Line Radius) for Bend Angle.
- 3.1416(2×2.2) = 13.823/360 = 0.0384.
- 0.0384 x 35 = 1.344”
- Offset Bend Calculation.

**What is the radius of a conduit bend?**

The radius is the distance from the center of that circle to the inside of the conduit. The circumference is the distance completely around the circle formed by the inside of the conduit and is equal to the radius times 6.28 (radius*6.28).

**What angles do PVC elbows come in?**

Elbows are most commonly available in 90-degree angles and 45-degree angles, so your pipeline can be directed however you want it.

#### What is the bend radius of 1 rigid conduit?

The bend radius of conduit benders are manufactured to meet NEC code for minimum conduit bend radii. A 1/2-inch conduit has a minimum bend radius of four inches, 3/4-inch conduit is 4 1/2 inches and 1-inch is 5 3/4 inches.
