Abstract
A load-sharing device shares electrical load between a high-ranking load and a low-ranking load. A current transformer connected between a circuit breaker panel and the high-ranking load senses current draw. The current transformer closes a first switch when sufficient current is detected and opens the first switch otherwise. Low-voltage power is connected across nodes of the first switch. A control circuit is connected in parallel with the first switch to control one or more second switches connected between the circuit breaker panel and a low-ranking load. When there is current flow in the control circuit, the second switches are closed, thereby permitting power delivery to the low-ranking load and when there is no current flow in the control circuit, the one or more second switches are open circuited. When the first switch is closed, it provides a short circuit, thereby preventing current flow in the control circuit.
