How Many Smoke Detectors On A 15 Amp Circuit_

Ten to Twelve Pieces. The National Electrical Code (NEC) does not specify how many smoke detectors can be installed in a 15-amp circuit, but does state that the total load on the circuit should not exceed the circuit’s rating. For a 15 amp circuit, the total load should not exceed 15 amps (or about 1800 watts).

Theoretical Value

Tipicamente, smoke detectors use a current of 0.3 para 0.5 amps each. Em outras palavras, if we have only detectors connected, a 15-amp circuit could theoretically support 30 para 50 smoke detectors. No entanto, this is only a rough estimate. E, it does not take into account other factors such as the distance between wires, other equipment or detectors.

Practical Suggestion

In practice, we suggest not to have too many smoke detectors on the circuit to avoid overload. It is usually recommended to limit the number of detectors to 10 para 12. This ensures that the circuit is not loaded for reliability. Overloading can lead to potential electrical hazards.
