re-tightening / overtightening connections

re-tightening / overtightening connections

RE: re-tightening / overtightening connections

Neither Cu nor Al connections should be "tightened" on a periodic basis. This will result in over-torqued connections. Over-torqued connections may eventually loosen and fail.

If you feel you must "maintain" then connection, the proper procedure is to loosen the connection and re-tighten to the specified torque.

RE: re-tightening / overtightening connections

The proper way to redo connections is to take them apart, clean them, and then re-connect. Just tightening or re-torquing does no good in most cases where a poor connection is already indicated due to local heating.
