ABSTRACT:
A power transfer device for electrically isolating two alternate power sources to a power distribution device so that only one power source is electrically connected to the power distribution device at one time. The power transfer device includes a first switch, connected to the first power source, having a actuator for operating the switch between an "on" position in which the first power source is electrically connected to the distribution pedestal, and an "off" position in which the first power source is electrically disconnected from the distribution pedestal, and a second switch, connected to the second power source, having a actuator for operating the switch between an "on" position in which the second power source is electrically connected to the distribution pedestal, and an "off" position in which the second power source is electrically disconnected from the distribution pedestal. A bar is slidably mounted adjacent the actuators on the first and second switchers. The bar can be slid between a first position in which the bar blocks the operator on the first switch from operating the first switch to the "on" position, and a second position in which the bar blocks the operator on the second switch from operating the second switch to the "on" position, thereby preventing both switches from simultaneously being in their "on" positions.
