    • Resettable circuit interrupting devices, such as GFCI devices, that include reverse wiring protection, and optionally an independent trip portions and/or a reset lockout portion are provided. The reverse wiring protection operates at both the line and load sides of the device so that in the event line side wiring to the device is improperly connected to the load side, fault protection for the device remains. The trip portion operates independently of a circuit interrupting portion used to break the electrical continuity in one or more conductive paths in the device. The reset lockout portion prevents the reestablishing of electrical continuity in open conductive paths if the circuit interrupting portion is non-operational or if an open neutral condition exists.
    • 提供了包括反向布线保护的可复位电路中断装置,例如GFCI装置,以及可选地独立的跳闸部分和/或复位锁定部分。 反向接线保护在器件的线路和负载侧都工作,以便在连接到器件的线路接线不正确地连接到负载侧时,器件的故障保护功能保持不变。 跳闸部分独立于用于破坏装置中的一个或多个导电路径中的电连续性的电路中断部分。 如果电路中断部分不可操作或者存在开放中性条件,则复位锁定部分防止重新建立开放导电路径中的电连续性。

    • A seal unit is provided for forming a seal between a pipe extending axially through a cylindrical hole, where said pipe is positioned eccentrically in said hole. The seal unit comprises a plurality of resilient compressible elastomer seal blocks, each block having a fixed height, a thickness and a width. The blocks are connectible to each other to form a ring, with a thickness of each block being arranged in a radial direction relative to the ring. A thickness of the blocks varies from block to block, with a smallest thickness block being arranged diametrically across from a largest thickness block in the ring. Intermediate blocks between the smallest thickness block and the largest thickness block have progressively increasing thicknesses leading from the smallest thickness block to the largest thickness block in each circumferential direction. The blocks can be compressed in an axial direction to cause them to expand in radial and circumferential directions, effecting a seal between the pipe and the hole.
    • 提供密封单元,用于在轴向延伸穿过圆柱形孔的管之间形成密封,其中所述管偏心地位于所述孔中。 密封单元包括多个弹性可压缩弹性体密封块,每个块具有固定的高度,厚度和宽度。 这些块可彼此连接以形成环,每个块的厚度相对于环在径向方向上布置。 块的厚度从块到块不同,其中最小的厚度块从环中的最大厚度块沿直径方向布置。 最小厚度块和最大厚度块之间的中间块在每个圆周方向上具有从最小厚度块到最大厚度块的逐渐增加的厚度。 块体可沿轴向压缩,使其在径向和圆周方向上膨胀,从而在管道和孔之间进行密封。
