What are ``combination`` AFCI devices?

By the UL 1699 definition, combination AFCI devices are intended to protect both branch circuit wiring and cord sets or power-supply cords. As a result, this type of device would provide protection against both high-energy parallel arcing (same as existing branch/feeder AFCIs) and low-energy (5A) series arcing.
