A line of 16-gauge thermostat wire virtually eliminates the possibility of voltage-drop issues and makes the wire more resilient to physical damage, according to company officials. The wire is constructed using a PVC jacket and conductors insulated with polypropylene. The 16-gauge wire is available in three, five, six, eight or ten conductors in lengths of 500 feet, packaged on a spool.
