ANSWER:
The 2001 California Electrical Code requires a minimum 100 amp-120/240 V single phase service for an average home (less than 1500 sf). If your home has excessive electrical loads you must use load calculations to calculate your minimum requirement per Article 220 of the 2001 California Electrical Code. For your information, examples of load calculations can be found in Appendix D of the electrical code.
