Issue:
Insulation test on 100ft of a 5000A busway.

Product Line:
I-Line

Environment:
North America products

Cause:
Test

Resolution:
Regardless of the busway amperage, the minimum acceptable megohm reading is 100 divided by the length of the run in feet. (100 / feet). For example, if the busway run is 50 feet long, the minimum acceptable reading would be 100 / 50 = 2 megohms.
