To determine the minimum distance that unshielded low-voltage circuits should be separated from power circuits to reduce electromagnetic interference (EMI), we need to follow the recommendation provided.
Here is a step-by-step solution to the question:
1. The problem asks for the recommended minimum distance of separation to reduce EMI.
2. We are given four options to choose from:
a. 2 inches
b. 12 inches
c. 24 inches
d. 36 inches
3. From the information provided, the recommended minimum distance for separating unshielded low-voltage circuits from power circuits is 12 inches.
Therefore, the correct answer is:
b. 12"
