Good day everyone, Constructing a 40 foot paver sidewalk that will go to driveway. Transformer will be right next to covered concrete porch which is accessible to GFCI in use outlet. I'm also running either a 10-2 or 12-2 AWG from the Transformer to driveway pillars which will be 150 feet away from the Transformer. I'm going to put conduit under the paver walkway for placement of VOLT path lights. I already have a trench completed from front of house to location of pillars. I would really like to have my 150 foot run of wire to pillars placed in conduit. I feel it's a better practice and much easier to pull wire for future changes or additions. My question is what kind of conduit is mostly used for low voltage wiring? PVC conduit or Metal ? I was told recently that low voltage landscape lighting wire gets hot enough to melt PVC. Which I find really hard to believe. I kind of laughed when I heard that statement because if it gets that hot it would melt the insulator.
Tom: PVC is fine. The flexible stuff Home Depot sells, for instance, is rated at up to 600 volts for in-ground usage. I have used both flexible and rigid PVC to protect my wiring in my wife's flower beds. Nothing has melted. Bob
