2.2.2 Type II. Type II (watersealed type) terminals shall be constructed as specified herein and in accordance with the applicable item (part number) specified in Drawing 7056700.
2.3 Performance. Terminals or splices, when connected to the intended conductor(s) by the applicable crimping tool, shall meet the performance requirements specified herein.
2.3.1 Voltage drop.
2.3.1.1 Terminals. The terminals and attached conductor shall be connected into a circuit adjusted to pass the current specified in table I. The millivolt drop shall be measured from the intersection of the torque and barrel to a point on the conductor 1/4 inch from the open end of the barrel. When terminals have conductor insulation supports, this point shall be 1/8 in from the end of the support. The terminals shall meet the “initial” voltage drop as specified in table I.
2.3.1.2 Splices. The splices and attached conductor shall be connected into a circuit adjusted to pass the current specified in table I. The millivolt drop shall be measured from a point 1/4 inch from the barrel of one conductor to a point 1/4 inch distant from the barrel on the other conductor. The splices shall meet the “initial” voltage drop as specified in table I except the “initial” voltage drop values shall be increased by 33 percent (%).

2.3.2 Current rating. The terminal or splice temperature shall not exceed by more than 9 degrees Fahrenheit (°F), the temperature of the attached conductor stranding. This shall be verified by attaching the terminal or splice to an appropriate size conductor and passing the current specified in table I through the test circuit.
