    • An alternative power source provides alternating current (AC) through a proper connector into a first outlet of a pre-existing electrical distribution system which is normally powered by an alternating current electrical power supply through main breakers and a breaker box. At least one of the breakers which controls power from the normal AC electrical power supply on the electrical distribution system is opened prior to connecting the alternative power supply. The alternative power supply provides electricity through the proper connector into the first outlet, or node, to provide alternating current to a selected portion of the electrical distribution system, and possibly to both halves of the pre-existing electrical distribution system if the proper connector is connected to a 240 volt outlet, or if two proper connectors are utilized and connected to first and second outlets with the first and second outlets on each of the two phase (power) wires of the pre-existing electrical distribution system.
    • 替代的电源通过适当的连接器将交流电(AC)提供给预先存在的配电系统的第一出口,其通常由通过主断路器和断路器箱的交流电源供电。 在连接替代电源之前,至少有一个控制来自配电系统上的正常AC电源的电力的断路器被打开。 替代电源通过适当的连接器将电能提供到第一出口或节点中,以向配电系统的选定部分提供交流电,并且可能地将预先存在的配电系统的两个部分提供给正确的连接器 连接到240伏特插座,或者如果使用两个适当的连接器并且连接到第一和第二出口,其中第一和第二出口在预先存在的配电系统的两相(电源)线的每一个上。

    • A brake evaluation gauge is useful to determine a brake lining thickness and/or brake drum wear. Depending on the particular embodiment selected, one of a thickness measurement, a percentage of brake life left, a pass or a fail indication may be indicated for the thickness of the brake lining. A first end of a gauge is inserted between a brake shoe table and a brake drum of applied air brakes to provide this reading. Furthermore, a recess in the gauge is placed over a ridge created by wear of the brake lining on the brake drum. If the ridge contacts the interior surface of the recess, then excessive wear of the brake drum is indicated.
    • 制动评估仪可用于确定制动衬片厚度和/或制动鼓磨损。 根据所选择的具体实施例,可以针对制动衬片的厚度指示厚度测量,剩余制动寿命百分比,通过或失败指示中的一个。 仪表的第一端插入在制动蹄台和应用的制动器的制动鼓之间以提供该读数。 此外,仪表上的凹槽放置在通过制动鼓上的制动衬片的磨损产生的脊上。 如果脊接触凹槽的内表面,则表示制动鼓的过度磨损。
