Wire, and wire installation, is a key factor in successful decoder installations. Substitution of wire and wire splices is at the installer’s own risk and is the major cause of start-up service troubles.
Hunter provides various wire models for use with ACC decoder systems. Hunter recommends the color-coded wire selections with outer jacket for additional protection of decoder wire.
|ID1GRY||Gray outer jacket||
14AWG/2.08 mm2 solid-core twisted pair, 2500 ft / 760 m per standard spool
(Use up to 10,000 ft / 3 km)
|ID1PUR||Purple outer jacket|
|ID1YLW||Yellow outer jacket|
|ID1ORG||Orange outer jacket|
|ID1BLU||Blue outer jacket|
|ID1TAN||Tan outer jacket|
|ID2GRY||Gray outer jacket||
12AWG/3.3 mm2 solid-core twisted pair, 2500 ft / 760 m per standard spool
(Use up to 15,000 ft / 4.5 km)
|ID2PUR||Purple outer jacket|
|ID2YLW||Yellow outer jacket|
|ID2ORG||Orange outer jacket|
|ID2BLU||Blue outer jacket|
|ID2TAN||Tan outer jacket|

The twisted pairs are not shielded or armored, but the outer jacket provides protection from abrasion and sunlight damage. Conduit is not necessary unless local regulations require it (the two-wire path is low voltage). Shielding, steel armor, and conduit will not inhibit performance and are permissible when desired.
Hunter requires twisted wire meeting the above specification on all paths. The twist in the wire is an essential part of the surge suppression scheme and works very well. The twist in the wire minimizes the difference in potential during a surge, and adds inductance. Since lightning damage is never covered by warranty, it is in the installer’s best interest to share what Hunter has learned in nearly two decades of decoder installations, by using twisted wire that meets all the above specifications.
Color coding is mandatory. The red/blue coding is a convenience for matching the wires to Hunter decoders. External colorcoded jackets aids in diagnostics after initial installation and protects wires from shorts to earth.
Using pre-existing wire: This is strongly discouraged by Hunter for the following reasons:
It is unwise to take chances on large projects by trying to "beat" wire specifications.
