Paragraph Number

71

In one embodiment, the directional power diode 606 is specified to operate at 240V and up to 70 A. The directional power diode 606 allows electric current to flow from the 240V line to the first electrical heating element 608, but stops electric current flow in the reverse direction. In another embodiment, the directional power diode 606 may be replaced by a power transistor configured to switch on when current flows from the 240V line and switch off when current flows from the 120V line.
