Iowa Residential Appliance Installer License Prep Class: Download the New

When it comes to preparing for the Iowa residential appliance installer license, it's essential to have a comprehensive understanding of electrical calculations and codes. In this article, we'll explore how to apply temperature correction factors and determine the required branch conductor size for a continuous duty motor.

Temperature Correction Factor Calculation

To start, let's consider Table 310.15(B)(1)(1), which outlines the temperature correction factor formula for calculating ampacity. With an ambient temperature of 117 degrees F, we need to apply the temperature correction factor. Here's the calculation:

155 A / 0.75 = 206.67 A

This calculation takes into account the reduction in ampacity due to high temperatures.

Required Branch Conductor Size

Next, let's determine the required branch conductor size for a continuous duty motor with a FLA (Full-Load Ampere) of 124 A and an ambient temperature of 115 degrees F. The terminals are rated at 75 degrees C.

To complete this calculation, you'll need to refer to your electrical code reference materials or consult with an experienced electrician. In this case, the required branch conductor size is crucial in ensuring safe and efficient operation of the motor.
