What reading level is Electrical Machinery a Practical Study Course On Installation Operation And Ma book?
To quickly assess the difficulty of the text, read a short excerpt:
The three right-hand columns in the table give number of strands used to make up the conductor, the diameter of each strand and the outside diameter of the conductor bare. It will be seen that the diameter of a stranded conductor is somewhat greater than that of a solid wire of the same cross-sectional area. For example, the outside diameter of a 250, 000-cir. Mil solid conductor is 500 mils, as given in the third column from the right, while the outside diameter of the same conductor stranded ...is 575 mils. This is due to the space between the strands.
A solid conductor can be measured with a wire gage, but not so with a stranded conductor. The size of the latter may, however, be determined by measuring the diameter of one strand in mils with a micrometer and squaring this diameter and multiplying the product by the number of strands. For example, a No. 2 conductor is made up of 7 strands 97. 5 mils diameter. The square of the diameter is 97. 5 X 97. 5 = 9, 506. 25 cir. Mils. The conductor is made up of 7 strands, then the total cross-sectional area is 9, 506.
