http://www.sparkyuonline.com In this video i show how to wire a 110 volt time clock that will operate a contactor. The contactor handles the electrical voltage from several different circuits.Time clocks and photo cells can be interconnected so that one can over ride the other. This is another in a series of online electrical course videos. Stay tuned for more how to videos beyond how to wire a GFI. Electrical wiring can be simple if described in a visual manner. Electricians and maintenance people can learn how to wire easy to complex electrical devices.
