[Tagging] Power=cable for low voltage lines?

Is there any limit to what can be mapped power=cable? Can micromappers use
this tag for wires connecting their house to a garage? Or a wire from their
garage to a string of light bulbs hanging across the back yard?
Should there be a different tag for power wires at the consumer level?
