For a single family residence in the United States, there is no code-mandated limit to the number of boxes on a 120-volt 20-amp circuit. You can put a thousand on if you want.

Normal convention is to put no more than ten.

But you are allowed to be smarter than normal convention if you have some kind of idea what you will be running on this circuit. The normal convention is used when you have no preconceived idea what this circuit might power.

If this circuit serves a kitchen, laundry room, bathroom, dining room, or pantry, then there are other restrictions you should be aware of. Also, if this circuit is serving a new addition, there are minimum power requirements you need to know.

Tell us more about your project and we will be able to give more specific advice.

Lightbulb More In Depth

Thanks for the help, for more insight I wired two circuits to my upstairs one carries 12 outlet boxes for my master bedroom and hallway, the other carries 11 outlet boxes for my two guest bedrooms. The lights upstairs have their own circuit. will this be ok?

If you have normal bedroom and hallway stuff on those two circuits you should be fine. If you are using and ironing board, window air conditioner, curling irons, hair dryers you may be popping breakers.

If the load is unknown and you don't go out and play tool time buying something big you should be fine.

Did you install smoke detectors in those bedrooms and the hall and interconnect them with the other smoke detectors that I hope you have in your home? Did you install the 120 volt powered smoke detectors with battery back up? Sure hope so for you family's safety sake. CABO Building Code requires them.

Did you use the arc fault breakers protecting those bedroom receptacles as the 99 and 02 NEC requires?

Good Luck
