There are 4 main wire functions in 120V/240V wiring: Hot - always "on" Switched Hot - "on" only when a switch (or combination of switches) is on; Neutral - the other half of each circuit (except 240V-only, which has two hots). Not usually switched.Not counting the wires from the fan itself, I have 3 sets of wires going into the fan box - 1 is for the switch, 1 leads to an outlet, and the other back to the main power source - so it appears the fan is in the middle of a circuit.
