    Default "FAU" marked on panel-???

    My electrician has written "FAU" on the panel next to two, 15A breakers. Any thoughts?

    FAU is "forced air unit", meaning your gas furnace or electric air handler.

    Not sure why it would need TWO breakers, however unless you have two units, and then they would usually identify them somehow. Left/right, East/West/North/South, etc.
