Abstract
A device for interfacing power from an electrical supply having power terminals, that permits implementation of a wide range of power cord lengths and voltage connection combinations. The device includes a body having a cord side and an appliance side. The body has four or more terminals located on the cord side of the body, with one terminal being a ground terminal. At least one electrical connecting device is adapted to connect terminals. In a first configuration, the device is used at a lower voltage. In a second configuration, the device is used at a higher voltage.
