Calculating the System Current Draw
Table 6.3 contains three columns for calculating current draws.
For each column, calculate the cur-
rent and enter the total (in amperes) in the bottom row.
When finished, copy the totals from Calcu-
lation Column 2 and Calculation Column 3 to Table 6.4 on page 41.
