While we're on the subject, how many disposals and DW's come with their own power cords ? I haven't seen a disposal yet that came with its own cord and I've come across one DW in all my years doing electrical work that came with its own cord. Why can't the manufacturers be mandated to install a label right on the unit stating "If not wiring direct and installing a cord and plug use only X or Y type of cord and plug to connect this unit" ? That way an EC doesn't have to go rummaging around to find a manual if an EI requests it.
Just something to add to my wish list.
