the square mil area of a conductor that is 0.250\ on all sides is ____ mils².
sec. ref. 2.1.1
55,000
62,500

Explanation:

Question 1

In a three - phase, four - wire delta system, the color reserved for identifying the high leg is orange. This is a standard color - coding convention in electrical systems.

Step1: Convert inches to mils

1 inch = 1000 mils, so a side length of 0.250 inches is $0.250\times1000 = 250$ mils.

Step2: Calculate square - mil area

The area $A$ of a square is $A = s^2$, where $s$ is the side length. So $A=(250)^2= 62500$ square mils.

Answer:

B. orange
