Transcribed Image Text:3. You are an electrician. You have been asked by a homeowner to install a lighted mirror
in a bathroom. The mirror contains eight 40-watt lamps. Upon checking the service
panel you discover that the bathroom circuit is connected to a single 120-volt,
20-ampere circuit breaker. At present, the circuit supplies power to an electric wall
heater rated at 1000 watts, a ceiling fan with a light kit, and a light fixture over the
mirror. The fan motor has a full-load current draw of 3.2 amperes and the light kit

Step 1
A homeowner has asked to install a lighted mirror in a bathroom. The mirror contains eight 40-watt lamps. The bathroom circuit is connected to a single 120 Volts, 20 Ampere circuit breaker. At present, the circuit supplies power to an electric wall heater rated at 1000 Watts, a ceiling fan with a light kit, and a light fixture over the mirror. The fan motor has a full-load current draw of 3.2 Amperes and the light kit contains three 60 Watt lamps. The light fixture presently installed over the mirror contains four 60 Watt lamps.
We have been asked whether the present light fixture over the mirror can be replaced by the lighted mirror or not. It can be assumed that all loads are continuous, can the present circuit supply the power needed to operate all the loads without overloading the circuit.
