What is the difference between a riser and plenum cable?
Riser cables, which are OFNR listed (UL 1666), are typically used in vertical applications such as elevator shafts or between floors in a building. Plenum cables, which are OFNP listed (UL 910), are typically used in horizontal applications such as in the air return spaces above ceilings and under structural floors in buildings since they generate little smoke.
