A friend wants to run low voltage wiring for his landscaping, but also wants to run some feeds for larger lights elsewhere in the yard. He only wants to punch one hole in his basement wall and was wondering if he could run the
12v wires from the transformer in the same conduit he uses to run a 120v feed for his other lights. I tried looking in the 2005 NEC, but it led me to other questions. In 300.3(C)(1) it says that the cables can be run in the same enclosure as long as the insulation of the lower voltage circuit was rated for the voltage of the higher voltage circuit. Then it says unless it's a class 2 or class 3 device see 725.55. What would the class rating of the low voltage lighting be?Thanks Shane
