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. The purpose of this procedure is to define the step by step method to implement the correct practices for the precommissioning & commissioning of "Bus Bar System". The main supply switch to the busbar is to be energized first. 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.
