To calculate the minimum number of 15-ampere branch circuits required in a dwelling, you should multiply the dwelling square footage by 3 volt-amperes to obtain total volt-amperes, divide by 120 volts to obtain the total amperes, and finally, ____.
A) divide by 15 and round up to obtain the number of circuits
B) multiply by 15 and round up to obtain the number of circuits
C) divide by 15 and round down to obtain the total number of circuits
D) multiply by 15 and round up to obtain the total number of circuits

Question

Quizplus · Accepted Answer

To calculate the minimum number of 15-ampere branch circuits required, after obtaining the total amperes, you divide by 15 (to account for each circuit's amperage capacity) and round up to ensure you have enough circuits to safely handle the load. This ensures compliance with safety standards and provides an adequate number of circuits for the dwelling's electrical needs.
