ABSTRACT:
A transformer wiring method and apparatus for fluorescent lighting are described. The fluorescent lighting apparatus includes a transformer and a ballast. An installer is easily able to balance the system load because each fluorescent lighting apparatus includes its own transformer and may be connected directly to a facility's three phase power distribution while still operating at rated voltages. Moreover, the ballast is protected from surges and stray voltages thereby reducing the frequency of ballast failures.
