    What is the correct way to run Low Voltage wire through an exterior wall?

    Hire a contractor who knows what he is doing :laugh:

    Most transformers are not rated for indoor mounting anyways. But to answer your question... it must be in conduit

    Properly sized conduit as per nec fill calculations. We run a lot of wire in the crawl space, but maintain our transformers outside as much as possible.

    It was a HIGH END Lighting Contractor. They have an office and display garden that I would say should easily would be worth $6-700,000. That's a BIG nut. A lot of the splices I saw, didn't look to great either.

    a few folks like light-house franchise, and my buddy in chicago ONLY mount inside, preferably in the garage on the outside wall.

    mount on stud, 3/4 " conduit, through wall and into ground out side, then out of conduit. I like outside, but really, these things should be safe inside.

    should be and what they are rated for is different. Im sure they will be fine inside but they are not all rated for it therefore its a liability issue. Im sure with snow areas and such it should actually be a bit safer inside but then again I cant reccomend it or do it without a trans rated for it.

    Another issue is serviceability.. Someone has to be home on your service visits.
