In a motor branch circuit where multiple motor disconnecting means are present, only one needs to be readily accessible to ensure rapid access during operation or in case of an emergency. This requirement is in place to facilitate safe and efficient operation, allowing maintenance personnel or operators to quickly disconnect power to the motor without having to search for multiple disconnects.

The rationale here is focused on the principle of ensuring safety while avoiding the complexity of having to access many disconnects. It helps streamline emergency procedures and minimizes the risk of confusion, which can arise if an operator has to choose which disconnect to access. Additionally, this regulation aims to balance the need for safety with practical considerations on the job site.

The other choices imply that either all disconnects, only a fraction, or none at all should be accessible, which would either overwhelm an operator in an emergency situation or could potentially compromise safety by not ensuring prompt access to at least one disconnect. Thus, having just one readily accessible disconnect provides a practical solution while adhering to safety standards.
