Using the correct torque when installing CSR breakers

Selecting the right torque driver and tips avoids damage to the Enpower lugs.

High quality installations are always important. Using proper torque when installing electrical systems is a critical step in this process.

Recap

  • For fixing the CSR Breaker upper lugs to Enpower, use 4Nm torque as indicated in the image and table below.
  • Please check the correct torque values for installing the CSR breakers in the image below before installing the breakers. Otherwise, the Enpower lugs could be damaged.
  • The latest Quick Install Guide emphasizes the correct torque values.

NOTE: The CSR breaker torque (28.2Nm) in the wiring table below is only for the CSR breaker bottom wiring lugs.
