It is normal for the busbar trunking system to emit a low intensity hum during operation.  Excessive noise may be an indication of a potential problem.If this occurs, it is recommended to:  Conduct an audio/visual inspection of busbar trunking system to locate source of origin of noise and to check for installation errors (For example: loose hardware, housing damage, misalignments and so on.) If cause of noise is detected, determine actions necessary to address causes for excessive noise.  If source or cause of excessive noise cannot be detected, please contact Schneider Electric forassistance.QGH3492101-01 11/201869Commissioning and Maintenance Occurrence of sparking at any point along the busbar trunking system is not normal.
