3.12.3 Dimensions. The dimensions of each connector shall be as shown on the
applicable specification sheet after the inspection of 4.5.3. Where only maximum or minimum
dimensions are shown, the connector need not have the shape shown, but the connector,
including all protrusions, shall be contained within the outline shown.
3.12.4 Weight. The weight of each connector shall be as shown on the applicable
specification sheet after the inspection of 4.5.4.
3.12.5 Dielectric strength. Breakdown of insulation shall not occur after being tested in
accordance with 4.5.6. The connector shall also meet the requirements of 3.11 during and after
testing.
3.12.6 Insulation resistance. The calculated resistance shall be not less than 10 megohms
after being tested in accordance with 4.5.7. The connector shall also meet the requirements of
3.11 during and after testing.
3.12.7 Operating torque (applies only to plugs). The torque required to engage the plug
with its mating receptacle shall be not greater than 11.5 pound-inches after being tested in
accordance with 4.5.8. The torque required to disengage the plug from its mating receptacle
shall be within the range of 5 to 11.5 pound-inches after being tested in accordance with 4.5.8.
The plug shall also meet the requirements of 3.11 during and after testing.
3.12.8 Contact resistance (applies only to plugs). The plug shall perform as follows
during the test of 4.5.9.
a. The voltage drop at 1500 amperes shall be not greater than 90 millivolts.
b. The voltage drop at 750 amperes shall be not greater than 45 millivolts.
c. The plug shall also meet the requirements of 3.11 during and after testing.
3.12.9 Receptacle strength test. The terminal blocks shall not break off, loosen, or rotate
with respect to the pin after being tested in accordance with 4.5.10. The pins shall not come
