HOLT Electricians Practice Exam

The statement regarding the requirement for the disconnecting means for a motor emphasizes that only one disconnecting means is necessary even if multiple means are available. This is based on the intent of electrical safety codes, which dictate that a motor must have a means to safely disconnect it from the power source for maintenance and emergency situations.

The rationale behind this requirement is to ensure that if there are several disconnecting means, the presence of multiple switches or devices does not complicate the disconnection process. In practice, having a single designated disconnect simplifies operations and enhances safety by making it clear where to cut power to the motor.

Options discussing the proximity of the disconnecting means, the requirement for labeling, or the capability for remote operation focus on different aspects of safety or operation, but they do not affect the fundamental requirement that only one method of disconnection is necessary. These can help ensure safety and operability but do not contradict the essential requirement of having at least one clear disconnecting means for motor control.
