Low Voltage Wiring, Halogen Light, Electrical Load Calculation & Direct Burial Cable

I wanted to know what the best way to connect a " Y "(or one into two) on my low voltage landscape lights.With the single end going to the transformer & then appx.50ft. out is where I need the " Y " connection at, & then continue out appx 25-35ft on each of those ends. Would I just tie into the main wire coming off the transformer? My light system output is 12v A.C. Thank you very much!

If you are planning to splice the wires and split the load you must first calculate the total amperage of the load. This is done by dividing the total wattage by the voltage and which is explained in our DESIGNING LOW VOLTAGE LIGHTING PAGE. If you are using 12/2 LANDSCAPE LIGHTING CABLE you must stay below 20 amps. FYI - 10/2 LANDCAPE WIRE is good for 30 amps. You can run 200 watts approximately 75-100' feet before you begin to experience voltage drop with #12. Although it may cost more, it is always better to run individual wires or install a continuous loop to avoid voltage drop. I would check with your transformer manufacture to see if a continuous loop sytem is right for you. Good Luck!
