Make Proper Connections

A properly tightened connection is essential in making sure the lugs do not heat up in the first place.

The Sept. 8 article by Mark Persons on overcoming the “tyranny of power” was very good. But he failed to drive home the point that a properly tightened connection, to the foot pounds specified by the manufacturer, is essential in making sure the lugs do not heat up in the first place.

The Square D disconnect switch he mentioned is one of the better products on the market and would not have failed twice had it been wired properly. Electricians are even encouraged to use a torque wrench when tightening these types of lugs to make sure the lugs are tightened to the correct foot poundage.

Time and again, as a broadcast engineer and troubleshooting electrician, I found lugs of all types burned up from high resistance because the wiring was not stripped properly, not inserted properly or not tightened properly — or, if aluminum, not properly coated with an anti-corrosion compound, and/or inserted in lugs where aluminum is not permitted.

That's right, no royalties on HD2 or HD3. They would give incentive to the stations to go out of their way to use the extra streams for new and untested waters.
