I suppose i overwire, having now roughed in a home with 60+ circuits (and counting).
All the dedicated circuits, (or rather , those i have made dedicated) are IMHO, a safety factor, and provide for what wiring of the 50's and 60's do not.

I'd like to hear from the board, i know some of you have been around when the 20 cir w/main was standard fare for the average residence.
