    • A ground anchor is provided for driving into the ground for anchoring or supporting a structure. The ground anchor includes a hub with a helical load bearing plate and a pointed ground engaging end having a body with a spade point blade extending axially from the body and the hub. The blade has first and second opposing spiral major faces and first and second transverse minor spiral faces that converge at a flat axial face to form the blade with a spiral configuration. The blade has a longitudinal dimension extending at an inclined angle with respect to a longitudinal center axis of the ground anchor so that the axial face of the blade is spaced outwardly from the center axis of the ground anchor. The leading edge of the spiral blade directs the soil to the leading edge of the helical plate of the ground anchor.
    • 地面锚具被提供用于驱动到地面中以锚固或支撑结构。 地面锚固件包括具有螺旋承载板的轮毂和具有从主体和轮毂轴向延伸的铲形刀片的主体的尖的地面接合端。 叶片具有第一和第二相对的螺旋主面以及在平坦轴向面处会聚的第一和第二横向小螺旋面,以形成具有螺旋构造的叶片。 叶片具有相对于地锚的纵向中心轴线以倾斜角延伸的纵向尺寸,使得叶片的轴向面与地锚的中心轴向间隔开。 螺旋叶片的前缘将土壤引导到地锚的螺旋板的前缘。

    • A rocker contact switch for a GFCI device includes a base and first and second legs extending from the base. When the base is moved, the second leg rotates to contact a conductive member to put the GFCI device in an end of life condition. The first leg is substantially prevented from moving in response to movement of the base. A test button of the GFCI device is pushed a first distance to complete a first circuit that trips the GFCI device. The test button is pushed a second distance, which moves the base of the rocker contact switch, to complete a second circuit that puts the GFCI device in an end of life condition by moving the rocker switch base.
    • 用于GFCI装置的摇臂接触开关包括底座以及从底座延伸的第一和第二腿部。 当基座移动时,第二腿部旋转以接触导电构件,以使GFCI装置处于使用寿命状态。 基本上基本上防止了第一条腿响应于基座的移动而移动。 GFCI设备的测试按钮被按下第一个距离,以完成跳闸GFCI设备的第一个电路。 将测试按钮推动第二距离,其移动摇臂接触开关的底部,以完成通过移动摇臂开关底座使GFCI装置处于使用寿命终止状态的第二电路。
