I have to agree with Speedy about the breakers. for instance, 5- 20 amp breakers are 100 amp but you'll never approach the current rating of the breaker in real life unless you have lots of heating circuits. In the front section of the NEC there are several methods of calculating a service entrance load size. other than architects I know of no contractor that actually uses this calculation.
