I do alot of residential work, more often there are some sort of prints if there are a few trades involved. If not I will lay it out with input from the GC or the homeowner and have them sign off on it.
Ther are a few factors for determining the load or amount of outlets for each circut. If the house dose'nt have central a/c , I usualy install 20a dedicated lines for each bedroom, dining rm and living rm. Another If there going to use a bedroom for a home office. Taking alot of the load off the general use outlets. Most customers even with no knowledge of electrical can appreciate and grasp the idea of what your explaining to them. Taking the time and having a little patience with the customer before jumping into a job, makes the end of the job alot easier. Have'nt had a call back for a tripped breaker in 6 years
