I have been getting conflicting information on checking or re-torqueing a wire termination. I have been taught that this should never be done due to the cold flow or relaxation that occurs over time. This relaxation has been accounted for in the original torque specification. If you check the torque by re-torqueing to the original value you will make the connection to tight and when the conductor heats up on high loads the pressure due to wire expansion will cause additional cold flow that may result in high contact resistance when the wire cools and had a low load.
Others have told me that the wire terminations should be re-torued to the original value at least once a year.
Anyone have any comments?
