1. You have been hired by a homeowner to install a ceiling fan and light kit in a living room. The living room luminaire (light fixture) being used at present contains two 60-W lamps. After locating the circuit in the panel box, you find that the circuit is protected by a 15-A circuit breaker and is run with 14 AWG copper wire. After turning on all lights connected to this circuit, you have a current draw of 8.6 A and a voltage of 120 V. The ceiling fan light kit contains four 60-W lamps, and the fan has a maximum current draw of 1.6 A. Can this fan be connected to the existing living room circuit? Recall that a continuous-use circuit should not be loaded to more than 80% of its rated capacity.

Question

Pratical application 1.)

**Practical Applications** 1. **Ceiling Fan and Light Installation** You have been hired by a homeowner to install a ceiling fan and light kit in a living room. The existing living room luminaire (light fixture) contains two 60-W lamps. Upon checking the circuit in the panel box, you discover that it is protected by a 15-A circuit breaker and uses 14 AWG copper wire. With all lights turned on, the circuit exhibits a current draw of 8.6 A at a voltage of 120 V. The new ceiling fan light kit includes four 60-W lamps, and the fan alone has a maximum current draw of 1.6 A. Determine whether this fan can be connected to the existing living room circuit, noting that a continuous-use circuit should not exceed 80% of its rated capacity. 2. **Industrial Plant Heating System** You are employed in a large industrial plant where a 480-V, 5000-W heater is used to melt lead in a large tank. It has been observed that the heater alone is insufficient to raise the temperature to the desired level. A second 5000-W heater is to be installed in the tank. Evaluate whether the electrical system can support this additional load after installation.
