Locate transformer(s) in a well-ventilated area away from direct irrigation spray and central to where the majority of the lighting fixtures will be installed. The goal is to minimize the length of cable runs from your transformer to the lighting fixtures, which minimizes voltage drop and cable size.
Transformer(s) with power cords must be located adjacent to a 120 volt GFCI protected exterior electrical receptacle. If a 120-volt power source is not available at the desired transformer installation location, it is advised that you hire a licensed electrician to run a dedicated 120-volt, 15 amp circuit to the desired location.
Test all existing receptacles with both a receptacle tester and a digital voltmeter or amp clamp to verify proper wiring and voltage at the receptacle.
When using only one transformer, it is very important to center the transformer on the wattage load. If the project calls for 135 watts in both front and back yard, the LUXOR Series Transformer should be centered on the side of the house that will receive the most lighting. A common mistake is to locate the single transformer on the service side of the house or in the garage, which might result in excessively long cable runs to reach lighted areas. The primary goal in laying out low voltage systems is to minimize cable runs because of voltage.
NOTE: If LUXOR is to be connected to Wi-Fi router, consider location within Wi-Fi range.
