Incorrect. The Buff Book provides a comprehensive understanding of fault current analysis, including interpretation of results.

Here are the key steps for conducting a fault current study, based on the Buff Book's guidance:

1. Define the System Configuration and Load:

   • Identify all components and their connections in the distribution system, including the panel, conductors, transformers, and loads.
   • Determine the expected load currents for each circuit and the type of loads (motor, lighting, etc.). This information helps define the potential fault paths.

2. Calculate Fault Currents for Each Circuit:

   • Use a fault current calculator or software to analyze the system and determine the available fault currents at each point in the circuit.
   • Consider factors like source impedance, conductor size, and fault type (short circuit, ground fault). The Buff Book provides methods and formulas for these calculations.

3. Select and Coordinate Protective Devices:

   • Choose appropriate circuit breakers, fuses, and other protective devices based on the calculated fault currents.
   • Ensure proper coordination between devices so that the correct device trips and isolates the fault without causing unnecessary shutdowns or damage to equipment.
