Abstract
Abstract A float controlled circuit breaker means operatively associated with an electrical cord capable of conducting electrical current to an electrically operable utilization means wherein the float controlled circuit breaker means is operable for interrupting a flow of current through the cord in response to the liquid level in an area reaching a predetermined elevation. The electrical cord includes circuit means supported therein for conducting an electrical current therethrough and having connector means on one end of the cord whereby the cord can be easily connected to an electrical power supply source. A float control means is affixed to the cord at a predetermined spacing there along and includes a float element operatively associated with a switch means supported in the connector means. The float element being operable for moving the switch means to an inoperable position to interrupt the flow of current in response to the liquid level in an area reaching a predetermined elevation. The switch means includes reset means operatively associated therewith for returning the switch means to an on current conducting position.
