Question

a) Must, 6 inches
b) Must not, 12 inches
c) Should, 18 inches
d) Shall, 24 inches

Answer 1

The Class A or Class X circuits should be separated by a distance of not less than 24 inches when run vertically.

Step-by-step explanation:

The correct answer is d) Shall, 24 inches.

The National Electrical Code (NEC) requires that Class A and Class X circuits must be separated by a distance of not less than 24 inches when run vertically. This separation is necessary to prevent cross talk or interference between the circuits.

For example, if you have a Class A circuit and a Class X circuit running vertically, they should be at least 24 inches apart to ensure proper functionality and safety.
