Yellow Wires

They control your air conditioning system. The yellow wires terminate at your compressor contactor via an air handler. The yellow wires connect to the Y terminals on your thermostat.

Is the yellow wire a hot wire?

Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.

Is yellow wire live or neutral?

  • Positive – red wire.
  • Negative – black wire.
  • Ground – white or gray wire.

Can 3 wires be connected together?

Multiwire circuits.

Three-conductor wire can be used to power a single circuit that would otherwise require two 2-wire circuits. For example, the black might feed a line of receptacles, while the red feeds a line of recessed light fixtures in the same area. The white is common to both (see illustration, below).
