I bought a 900Watt low voltage lighting transformer (3 circuits of 300 Watts each). I can put the transformer indoors and run three low voltage wires outside. Or I can run a 110V line outside and put the 900W transformer outside against the house wall. The transformer is rated for both indoor and outdoors. are there any advantages to putting the transformer indoors versus outdoors? Trying to decide if I should put it inside or outside. Thanks for any recommendations/advice.
