This single-feed surface transformer converts standard 120 line-voltage to 12 volts to provide the necessary voltage for powering a Kable Lite low-voltage lighting system. It can power lamps totaling up to 300 watts. The transformer is concealed inside a decorative housing with a fast acting secondary circuit breaker that will safely turn the system off should a short occur. Once the short has been removed the unit can be reset by simply flipping the wall switch off and back on.
