Referencing the above question, what is the correct answer expressed in paper amps?

• A. 8A
• B. 10A
• C. 12A
• D. 15A

Answer: (B)

Derating to find the paper amps means adjusting the conductor’s capacity for the actual installation conditions (like ambient temperature, how many conductors are in the same raceway, insulation rating, etc.) and using that conservative value for planning and protection. In this scenario, applying those derating factors yields 10 amps as the permissible continuous current. That 10-amp value is the one you document on the project to reflect what the wiring can safely carry under the given conditions. The other numbers would not align with the derating provided by the installation details.
