I'm adding 1,000 sq. ft. that contains a bedroom, den, two full baths, a laundry, and an a/c system. I want to run all the wiring myself and install all the plugs to code, and then bring in an electrician to tie it all into the powergrid and add new breakers/breaker boxes. I'm looking for information about basic items like gauge of wiring, location of outlets, switches by code. Any takers?
