1 - Based on: 105°C rated or better cable of the largest size. Properly calibrated APP® 
      recommended tooling, and a 25°C ambient temperature. UL rating not to exceed the 
      maximum operating temperature. CSA rating below a 30°C temperature rise.
2 - Limited by the thermal properties of the connector plastic housing.
3 - Use APP® recommended tooling only. Alternate tools may adversely affect the 
      performance of our connectors along with UL and CSA recognition.
