For a standard 120 volt circuit, the National Electrical Code (NEC) recommends a maximum of 12 outlets. However, this maximum number can be increased if the outlets are spaced evenly along the length of the circuit and if they are not used for high-powered appliances. In addition, some electricians recommend that each outlet have its own dedicated circuit, regardless of the number of outlets on the circuit. This helps to prevent overloading and minimize the risk of fire. Ultimately, the best way to determine how many outlets can be on a particular circuit is to consult with a qualified electrician.
