of the wall. In some instances, the use of a p-ring may be
inappropriate, such as in a retro-fit (existing) installation, or
when building codes require that wall devices be enclosed
in electrical boxes. Contact your local building code and
inspection department if unsure.
Type of Speaker Wire
For most applications, we recommend you use 16 or 18
gauge, stranded copper speaker wire for the VCS-2D-HP
connections. For wiring runs longer than 80 feet, 14 gauge
wire is recommended. Using speaker wire larger than 14
gauge for the VCS-2D-HP connections is not recommend-
ed—the wire may not fit into the connectors. Never use
solid-core, aluminum, or “Romex” type wire with the VCS-
2D-HP. When running speaker wires inside walls, most
states and municipalities in the U.S. specify that you must
use a special type of speaker wire. Usually, the requirement
is that the wire has a specific “CL” fire rating, such as “CL-
2” or “CL-3”. Consult your Niles dealer, building contractor,
or local building and inspection department if unsure about
which type of wire is best for your application.

"Tech Tip"
Wire size is
expressed by it's
AWG (American
Wire Gauge)
number. The lower
the AWG number,
the larger the wire,
i.e., 12 AWG wire is
physically larger than
14 AWG.
