Which of the following currents is not classified as objectionable under specified regulations?

The classification of objectionable currents is based on the impact they have on safety, equipment performance, and overall system integrity. Temporary currents from abnormal conditions generally refer to scenarios that are not typical during normal operations, such as transient faults or surges that may occur due to equipment malfunctions or environmental factors. These currents are often brief in duration and do not consistently create harmful effects on the electrical system or equipment.

In contrast, other types of currents listed, such as ground faults from normal operation, continuous ground currents, and currents creating electromagnetic interference, are consistently viewed as problematic. Ground faults can indicate issues with grounding and may result in electric shock hazards. Continuous ground currents represent ongoing leakage paths that can lead to overheating or equipment failure, while currents that introduce electromagnetic interference can disrupt sensitive electronic equipment and communications.

Therefore, temporary currents from abnormal conditions, being transient and generally resolved quickly, are not typically deemed objectionable under regulations, as they are not part of the standard operational parameters that are expected to create ongoing issues.
