1.) Remove references to “dummy elements” in 6.2.4 and 6.2.5.2. (They are non-existent in low-voltage equipment.) Replace with text similar to that found in C37.51-1989, 4.7 and 4.8. 2.) Table 10 contains “square centimeters” in the title, but the table units are in square inches. Correct table to square centimeters.
