4. Use the 80% efficiency factor to determine how much power is delivered
per circuit. [58 Watts * .8 = 46.4 Watts]
5. Divide your total load by the power delivered per circuit to determine the
minimum number of circuits required to support the load. [ 600 Watts / 46.4
Watts = 12. 93 circuits or 13 circuits.]
6. Add cards to reach the level of redundancy desired. [ One card redundancy
so 16 circuits or 8 cards.]
