Southwire Thermostat 250 553105407

The Southwire 553105407 is multi-conductor thermostat cable supplied in a 250 foot package.

A general note on control cable selection: the specification that matters most is not usually gauge or insulation type but conductor count, because that is the one which cannot be changed after installation without running new cable.

Gauge affects voltage drop, and the difference between 18 and 20 gauge matters only on long runs or circuits with several devices in series. Insulation and jacket type matter where the cable passes through a plenum space, where a plenum rated cable is required by code, or where the environment is unusually hot or damp.

Conductor count, by contrast, determines what the installation can support for the rest of its life. A cable with too few conductors constrains every future equipment decision, and correcting it means opening finished construction.

The practical guidance follows directly: select generously on conductor count, select gauge according to run length, and select jacket type according to where the cable runs.

Where a plenum space is involved, plenum rated cable is not optional and standard cable must not be substituted.

Applications include residential and light commercial thermostat, zoning, and control wiring.
