The motor disconnecting means is not required to be within sight of the motor if the required controller disconnect is capable of being individually locked in the open position. Is this statement true or false?

True
False
Depends on the installation
Only if specified by the manufacturer

The correct answer is: True

The statement is true because the National Electrical Code (NEC) allows for certain exceptions regarding the placement of motor disconnecting means. When a motor controller disconnect is designed to be individually lockable in the open position, it fulfills safety requirements, as it ensures that the motor can be safely maintained or serviced without risk of accidental reactivation. This feature provides reassurance that the power can be effectively isolated. In such situations, the NEC recognizes that the disconnecting means does not necessarily need to be within sight of the motor since the locking capability mitigates the risk associated with being unable to see the disconnect while still ensuring operational safety. In the electrical industry, this is regarded as a best practice, enabling flexibility in installation while still adhering to safety regulations.
