I'm wiring a project outdoors and burying a pair of power cables to each - 12V 5A (isolated grounds, so 4 wires to each). The wires run 25 feet each and need to survive animals, rock shifting, winter frost, etc. I was using two 14-2 UF cables for each which is very stiff and rated for underground direct burial (http://www.southwire.com/products/UFBOEM.htm). This works but requires double the wiring and double the cable gland entries to my enclosures.
Is there any reason why direct burial rated speaker cable won't work? It comes in 4 conductor versions so will save a lot of work. Although the same gauge it is much thinner overall and more flexible which is great but also a cause for concern. I really don't want to use rigid conduit. Here's an example of a cheap thin version - http://amzn.com/B008VRQ2QA, and here's an example of an expensive fatter version with an extra layer of protection - http://www.htd.com/4-conductor-direct-b ... aker-cable. The manufacturers say they are "not approved" for non-audio applications, but wire is wire right?
