A terminal has a torque value the way a conductor has a size. It is a number you look up and apply, not a feeling in your wrist.
Under-tightened is a high-resistance joint that heats. Over-tightened damages the conductor or the terminal. Both are invisible once the cover is on, and both are avoided by the same thirty seconds of work.
The specification belongs to the connection, which means the device and the conductor together -- not to lugs in general. A value that is right for one lug is simply a different lug's number when applied to this one. Getting the right one means obtaining the specification for the device in front of you.
Check yourself: A similar lug nearby is marked with a torque value. Can you use that number on this one?
Answer: No. Obtain the device specification instead of borrowing a number from another lug.
The torque value is specified for a particular connection. Another device's number was determined for that device, and similarity is not the same as sameness.
