What is the maximum allowable length of a motor feeder tap conductor?

• A. 15 feet
• B. 25 feet
• C. 35 feet
• D. 40 feet

Answer: (B)

The maximum allowable length of a motor feeder tap conductor is indeed 25 feet. This specification is crucial for ensuring that power is delivered efficiently and safely to motors. The limitation on the length of the feeder tap helps to reduce voltage drop, which can adversely affect the performance of the motor if the conductors are too long. By maintaining this maximum length, the electrical system is more reliable, reducing the chance of overheating and ensuring that the motor operates correctly and efficiently. This requirement is typically outlined in the National Electrical Code (NEC), which provides standards for safe electrical installations. Following these guidelines is essential for both safety and compliance with regulations within the electrical industry.
