How To Size A Low Voltage Transformer For Landscape Lighting

Maximum of 5 fixtures per each 12-2 gauge wire run.

How to size a low voltage transformer for landscape lighting. The wattage of all the low voltage landscape lights added together needs to be less than 80 of the transformers capacity. Transformers generally range from 150-. If you want to figure out how much power you need for your strip driver take the length of the tape you have and divide it by the wattage.

Total watts on low voltage wire length of wire run in feet wire size constant listed in chart below VOLTAGE DROP. Many set up landscape lighting for diverse reasons and your components determine the result. Add the wattage of all the lights.

For example if you intend to use 20 pieces of 12-watt lights multiply 12 times 20 for the total wattage needed. When operating low voltage lights you need a transformer to convert your standard line voltage 120V or 277V into low voltage 12V or 24VThis allows your lights to function properly. 8--Millennium Cabinet High Output Spot Light.

Select a relevant low voltage landscape light transformer. Choosing a driver for your landscape is dead easy so long as you follow these simple 3 steps. Then you must multiply the total wattage by 125 to adjust for loss due to cable distance.

Remember wire for low voltage landscape lighting comes in different gauges. Use this voltage drop equation to figure out how many volts your wire will lose over a distance. In this example the total wattage is 240.

Low voltage landscape wiring or electrical cable comes in several numerical gauges or sizes. Once your landscape lighting design is complete you can figure out what size of low-voltage transformer you need. Voltage drop is the amount of voltage lost due to resistance in the wire.
