DonTx Posted May 6, 2004 Report Share Posted May 6, 2004 Are thermostat wires running to the A/C required to be in conduit if they are ran under the ground? Donald Quote Link to comment Share on other sites More sharing options...
swarga Posted May 7, 2004 Report Share Posted May 7, 2004 I don't know. To my knowlage there is little regulation on low voltage wiring. When I used to install commercial HVAC we never used a etat wire that was approved for underground use. Sorry I could not be more help Quote Link to comment Share on other sites More sharing options...
Brian G Posted May 7, 2004 Report Share Posted May 7, 2004 That's a good question Donald, but I doubt if anyone has a firm answer. I'd bet money they aren't rated for it, but I'd also bet money they aren't rated for exposed outdoor use either. I see that all of the time. Brian G.

charlieb Posted May 7, 2004 Report Share Posted May 7, 2004 Typical bell wire is not rated for direct burial or uv exposure. However, rated wire can be obtained from an irrigation supplier such as John Deere Landscapes. It is use for short timer runs, rain sensors and to supply power to low voltage lighting in trees. Due to the voltage loss, it only supplied power from the ground to the fixture in lighting applications. Quote Link to comment Share on other sites More sharing options...
