Too many things on one breaker?
The NEC doesn't have and actual limit for number of receptacles per circuit in dwelling units. It gives a complicated calculation initially based on watts per square foot, then says [NEC 210.11(B)] that the loads are to be &quot;evenly proportioned among multioutlet branch circuits&quot;.
There is a specific rule for other than dwelling units of 180 watts per yoke which works out to 10 to 13 receptacles per circuit. Some people misapply that to dwelling units. In some installations that calculation works acceptably, but not always. Rules for receptacle placement in wall sections 24&quot; or wider and distances between receptacles not crossing doorways can sometimes add up to more receptacles per square foot than is proportional.
That being said it sounds like maybe the house was out of compliance to begin with, and without knowing what the instructions to your electrician were it does sound like you may have is a breach of contract or at very least a misunderstanding by the electrician of your intensions. It is also possible he didn't understand the the full impact of the work he performed, and a larger scope and bill would be necessary to meet your needs.
