Can low voltage transformers be mounted indoors?
Transformers make it possible to power and operate low voltage lighting systems by converting your home’s 120V line voltage power feed to the lower voltage (usually 12V, sometimes 24V) that low voltage lighting is designed to use. Indoor transformers are designed and rated for indoor use only. See Outdoor Transformers.

What size transformer do I need for a light fixture?
Most transformers are rated to handle a load of 100 to 300 watts; the higher the rating, the longer the cable—and thus the more light fixtures—you can connect to the system. If you want to add more lights, you may need a bigger transformer; if so, it’s probably more economical to buy a whole new system in a kit.
