REVIEW Refer to the National Electrical Code or the working drawings when necessary. Where applicable, responses should be written in complete sentences. Row 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Complete the following table using the following circuits: 1. Eleven 120-volt duplex receptacles for general use. Receptacle loads are considered to be noncontinuous and are not subject to the 80% load limitation as applied for con- tinuous loads. Row 1: Row 2: Row 3: 2. Ten 120-volt fluorescent luminaires, rated at 150 volt-amperes each. 3. Eight 120-volt incandescent luminaires, rated at 200 watts each. 4. One 240-volt exhaust fan, rated at 5000 watts. 5. One 120/240-volt single-phase, 3-wire feeder, 40-kVA continuous load, originating in a room with an ambient temperature of 100°F (38°C).
