To correctly apply 314.28(A)(1), just multiply the largest raceway size by eight. The box must be at least as long as that number. Angle pulls, u-pulls, and splices.To avoid this issue, use a box size about 150 Å larger than the average diameter of your particle and choose a preferred box size from the table below. For example, if your target particle is 100 Å wide in the micrographs and your Å/pixel size is 0.8 Å, your preferred box size would be 260 Å, or 325 pixels.

#1 I have an installation where (3) 4" EMT conduits will be entering a pullbox from the bottom, and exiting out the back (at the top) Assuming that I'm correct that since the conductors don't exit directly across from each other, the calculation would be (6x4")+4"+4" = 32" so a 32" x 32" box. My real question is concerning the depth of the pullbox.To find the acceleration down an inclined plane: Determine the angle of the inclined plane, θ. Hint: the ratio of ramp's height and length. Evaluate the sine of this angle, sinθ. Work out the cosine of the angle and multiply it by the friction coefficient, f × cosθ. Subtract result of step 3 from step 2: sinθ - f × cosθ.

Then, divide the cubic size of the package in inches by the DIM divisor to calculate the dimensional weight in pounds. Note: For non-square packages, you would take the longest dimension on each side and round …Boxes containing 4 AWG or larger, under 600 volts, are calculated from the sizes and numbers of raceways. Where pull and junction boxes are used on systems over 600 volts, the installation must comply with the specifications in 314.70. Three types of calculation procedures are provided: straight pull, angle pull and U pull.

Motor Sizing Calculations. There are three factors to calculate when sizing a motor; Moment of Inertia, Torque, and Speed. Moment of Inertia. Moment of inertia is the measure of an object's resistance to changes in its rotation rate. When an object is just sitting without any motion, the moment of inertia is 0.When determining the minimum size box for conductors 18 AWG through 6 AWG, the sizes and numbers of conductors are needed to calculate the minimum size box. Calculations are different for pull and junction boxes. Boxes containing conductors of 4 AWG or larger, under 600V, are calculated from the sizes and numbers of raceways (see Figure 1).

To calculate the size of the circuit breaker needed, we have to multiply the amp draw by 1.25 factor like this: Minimum Circuit Breaker Size = 12.5A × 1.25 = 15.63 Amps.
