The Kichler 15E120BK Economy Series 120-Watt Transformer is an economical choice for small jobs or single specialty piece applications. The Economy Series Transformers are available with a black polymeric enclosure which resists corrosion. This transformer has an easy connect terminal blocks, an on/off/auto switch, and an on/off switch.

The 15E120BK is featured with an auto-resettable in-line primary overload protection, as well. There is a thermal cut-off on the primary side if the need arises, and a thermal reset breaker on the secondary side. Your transformer selection will depend on the lighting job; size of the design layout, watts required and length of runs. Voltage drop will result in your lamps decreasing in brightness the farther they are from the transformer. Keeping runs as short as possible will minimize voltage drop and maximize light output.

To figure voltage drop, use this equation: A (length of wire) x B (total number of watts for all lamps on that wire run) = C (cable constant - determined by wire size). Cable constant for each wire gauge is as follows: 10 gauge-11920, 12 gauge-7500 (no more than 250 watts or 200 feet), 14 gauge-3500 (no more than 200 watts or 150 feet), 16 gauge-2200 (no more than 150 watts or 100 feet), and 18 gauge-1380.

This is UL rated for wet locations and is for exterior use only, but is not approved for use with fixtures placed in ponds or landscape water features. Unlike many others, Kichler Landscape Lighting Transformers feature epoxy encapsulation for greater protection and performance, secondary protection and auto-reset circuit breakers.
