photocells

Photocells are used for turning lights on and off.They can be used with a time clock but that is mostly done in commercial applications.The average home owner uses them for security such as lighting up a porch or back yard.Some lighting comes with the photocell already in the light thse are an easy hook up ,just add 120 volts and the light should come on when it gets dark (some require some ajustment).If you have ligts already installed and want to add a photo cell.All you have to do is find where power is being fed to the light and break the switch here.You can feed a row of lights as long as they do not exceed the wattage of the photo cell.There is a black,red and white wire on the photocell.The black goes to the line or (incoming voltage) the red is the load or (votage going out to light)the white wire ties all the nuetrals together.The red wire is only hot when it is dark or the eye is covered.I hope this helps you out ,as always if you have any questions give me a call 361 433-6039.You can click on 2011 below to see pictures of jobs and other helpful hints and videos that i have posted.
