A number of 120-V household fixtures are to be used to provide lighting for a large room. The total lighting load is 8 kW. The National Electric Code requires that no circuit breaker be large than 20 A with a 25% safety margin. Determine the number of identical branch circuits needed for this requirement.
Answer to relevant QuestionsA 5.1-kW household range is designed to operate on a 240-V rms sinusoidal voltage, as shown in Fig. P9.67.
