For 277, two wire lighting system, a fluorescent lighting fixture has a ballast with a nameplate rating of 185 W. Determine the number of such fixtures that can be connected to a two-wire circuit protected by a 20 A circuit breaker if the fixtures are used in an office building where they will be on for 8 hr continuously each day.

Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?

Which of the following statements about fluorescent lamps is correct? a. Fluorescent lamps have positive electrical resistance, meaning that the resistance increases with the flow of current. b. Fluorescent lamps can be operated without a ballast because they self-limit their current consumption. c. The ballast in fluorescent and HID lamps serves as a transformer to boost voltage and a choke to limit the flow of current. d. Fluorescent lamps don’t need a higher voltage to initiate the electric arc. e. Once an arc is struck in a fluorescent lamp, the ionized mercury vapor reduces its conductivity, limiting the flow of current.
