I asked this question a week or so ago and think I may have confused folks. All of these power packs state for outdoor installation only. I called Malibu technical service and all she told me was that it was the UL code. More simply put, does anyone know of a concern if I mount and plug in my transformer in my basement, and run the low voltage wiring through a small hole to the outside for my outdoor ground lighting? Hope that's clearer, thanks for any thoughts!
