How to fill out grounding nomograph - aemc

How to fill out grounding nomograph - AEMC:

1. Familiarize yourself with the AEMC grounding nomograph and understand its purpose and components.
2. Gather the necessary information such as soil resistivity, ground fault current, ground fault duration, and desired tolerable step voltage.
3. Determine the appropriate scale to use on the nomograph based on the available information. This can be done by evaluating the values against the chart's ranges and selecting the closest match.
4. Locate the starting point on the nomograph corresponding to the soil resistivity value.
5. Follow the lines on the nomograph to connect the point representing the ground fault current, duration, and tolerable step voltage.
6. The point where all the lines intersect will provide the desired minimum grounding resistance.
7. Once the minimum grounding resistance is determined, adjust the grounding system accordingly by adding or modifying grounding electrodes, conductors, or other components as necessary.
