    • Electrical load controls are provided which include an electrical switch assembly and a fault protection device within a common housing. The switch assembly includes an actuator, and is responsive to actuation of the actuator to switch ON or OFF electricity to the load. The protection device automatically responds to a fault condition by overriding the switch assembly by automatically blocking electrical connection between phase input and output terminals and neutral input and output terminals of the load control. The actuator includes a single external interface element. In one embodiment, actuation of the actuator switches ON or OFF electricity via control of the fault protection device, and in another embodiment, movement of the interface away from the housing exposes within the housing an internal user interface for the fault protection device.
    • 提供了电气负载控制,其包括在公共壳体内的电开关组件和故障保护装置。 开关组件包括致动器,并且响应于致动器的致动以将负载打开或关闭电。 保护装置通过自动阻断相位输入和输出端子与负载控制的空档输入和输出端子之间的电气连接来覆盖开关组件,自动响应故障状态。 致动器包括单个外部接口元件。 在一个实施例中,致动器通过故障保护装置的控制来接通或断开电力,并且在另一个实施例中,接口远离壳体的移动在壳体内暴露出用于故障保护装置的内部用户接口。

    • One embodiment relates to a fault circuit interrupter comprising at least one grounded neutral sensor and at least one test circuit configured to test the grounded neutral sensor. A further embodiment can also include at least one fault circuit which is configured to detect a current sent from the grounded neutral sensor. The device can also include a line side phase line, a line side neutral line, and a test line coupled to the line side neutral line and extending from a first region on the line side neutral line to a second region on the line side neutral line, with the grounded neutral sensor being positioned between the first region and the second region on the line side neutral line. This test circuit can comprise a switch, such as a manually operatable switch or it can comprise any one of solid state circuitry, a transistor, and/or a silicon controlled rectifier. The device can also include a differential sensor and at least one second test circuit configured to directly test differential sensor. The device can also include a processor in communication with any one of the above test circuits, wherein the processor is configured to initiate a self-test. At least one embodiment of the invention can also include a process for testing a fault circuit. This process includes creating a simulated grounded neutral fault, determining whether the simulated grounded neutral fault is correctly detected, and then indicating a result of the test to a user.
