A terminal assembly is to be supplied for both the maximum rated and the minimum cross section conductors. The terminal block is to be mounted using its normal mounting means.
An unprepared conductor of the maximum rated cross section is to be inserted in the terminal assembly and an unprepared conductor of the smallest cross section of the connector capacity
(if specified) in another terminal assembly, and the clamping screws tightened to 110 percent of the specified torque and its exceptions. The clamping screws are then to be unscrewed and new conductors inserted, and the screws tightened as previously specified. The test is to be repeated five times using the same clamping units and five new conductors for each terminal.
 
对于最大额定和最小横截面导体，都要提供一个终端组件。端子座使用其正常的安装方式安装。一个措手不及的最大额定导体截面要插入的终端装置和一个措手不及导体连接器的最小截面能力在另一个终端装置(如果指定了的话),和夹紧螺丝收紧1.1倍的额定扭矩及其例外。然后将夹紧螺钉拧开，插入新的导线，并拧紧螺钉。
