For simple bus bars, the ampacity tables are often enough, but parts with more complex geometries or multiple input/output connections, introduce variables that will skew performance from basic estimations. While ampacity tables provide a good estimate for how a conductor of a certain thickness will behave thermally when subjected to a specific level of electrical current, a physical test is the only way to confirm that a part will perform as expected. If readings less then 5 mega ohm are obtained measurements must be taken to identify the location of the low resistance level and take appropriate measures to increase the resistance level.
