lights How to Size a Transformer for Landscape Lights

Landscape lighting adds safety, safety and beauty.Once your landscape lighting design is completed, you can know the lowThe voltage transformer you need.Transformers are generally from 150-to 900-watt capacity.Matching the size of the transformer with the lighting design is essential for the efficient operation and function of the system.The transformer reduces the house current (120 V) to 12 to 20 V, which is the current required to operate low powerVoltage landscape lights.Many Transformers are connected with different wattage lamps for versatility.Other low-Voltage transformer functions include motion detectors for turning on and off lights, photo units for turning on lights in specific light, and programmable timers.In the landscape lighting design, add the wattage of each lamp.For example, if you plan to use 20 12-Wattage, total wattage multiplied by 12 times 20.In this example, the total wattage is 240.Multiply the total wattage by 1.25 adjust the loss due to cable distance.240x1, for example.25 = 300.The final number determines how much transformer your system needs.Select a transformer that is not less than the required wattage and does not exceed 33%.Choosing a transformer with a slightly larger power will allow you to add some lights in the future.Low-The voltage transformer is installed on the outside and plugged into the home current through the external power outlet.Fifteen-amp 120-The Volt circuit can carry 1440 Watts.Before adding the transformer to a specific outlet, check other appliances or systems that the circuit has already used.
