E3909.2 Loading and protection. The ampere load of flexi-
ble cords serving fixed appliances shall be in accordance with
Table E3909.2. This table shall be used in conjunction with
applicable end use product standards to ensure selection of
the proper size and type. Where flexible cord is approved for
and used with a specific listed appliance, it shall be consid-
ered to be protected where applied within the appliance list-
