hi,
The subject resistance is the system of an aluminum conductor supplied by the test lab, plus the bus bar assembly (bar plus the wire mounting hardware which are a sliding receiver and a big set screw). We have no control over the preparation of the aluminum conductor; all we can control is...
We are developing a bus bar for a utility customer that wants a C119.6 certification. The test spec they require involves 500 four-hour current cycles at 950 amps, 2 hours on followed by 2 hours off. Resistance is measured in micro Ohms and once a baseline resistance for the bar assembly (bar...
