While National Electrical Code (NEC) does not specify a strict numerical limit on the absolute number of standard downstream receptacles you can wire after a single master Ground Fault Circuit Interrupter (GFCI) outlet, standard residential electrical practice generally recommends limiting it to ten to twelve outlets per branch circuit. This practical limit prevents total circuit amperage from exceeding the 15-amp or 20-amp rating of the breaker wire gauge and reduces voltage drop over long wire runs. You can troubleshoot circuit capacities easily by counting connected devices and checking breaker ratings. You can verify that your installation is correct when wiring downstream standard receptacles correctly from the "Load" terminals ensures every outlet is fully protected against ground faults without overloading the branch circuit.
