Yes maybe, depending on what you are doing.1) Electric Code generally says Maximum 12 boxes per electric circuit controlled by 1 circuit breaker. If you have more boxes, then your house can fail inspection IF inspector finds problem. But it is a minor problem if wire size, breaker size, and amp loads are safely matched.

Calculate total amps and watts expected on that circuit.Add up watts of everything running at same time.Volts x amps = watts120 volt microwave uses 1500 watts, how many amps?Amps = watts divided by volts, so 1500 watts divided by 120 volts = 12.5 amps.Compare your total expected amp usage to charts on following link.Make sure you have correct wire and circuit breaker for expected amps. Oversizing wire and breaker are good idea.
