If you are using a battery drill, keep upping the torque until the screw strips on a old sample screw-then set it for 50% of that stripping value. Question: as the battery gets weak, does the torque, say, at level 4.5, change? For large lugs,I use an automotive-type visual torque wrench-I have had problems with the clicking type. Also,I do not see the problem with re-torqueing. 60 inch/pounds is 60 inch/pounds-all day long. I could be proven wrong, but,I think it would take a huge amount of pressure, say, 150% of the torque value, to damage the conductors. Also I thought "cold flow" was the initial electric current when equipment is energized. A connection that is too loose will arc during cold flow, but stop arcing when the wire is heated up. A normal conection will not arc during cold flow. Is that correct?
