The smallest conductors allowed for an outboard motor connected to a 120/240-V supply are how many AWG?

The smallest conductors allowed for an outboard motor connected to a 120/240-V supply refer to the minimum wire gauge that should be used to ensure safe and efficient operation. The National Electrical Code (NEC) provides guidelines to ensure that conductors can handle the electrical load without overheating and posing a fire hazard.

In this case, an outboard motor typically draws significant current, especially at startup. The choice of 8 AWG is based on factors such as the motor's current rating, the length of the conductor run, and the potential for voltage drop. Using 8 AWG ensures that the wire can safely carry the current required for the outboard motor without exceeding temperature ratings or risking voltage drop issues.

Selecting a wire gauge that is too small could lead to overheating, increased resistance, and inefficient performance. Therefore, the 8 AWG conductor is recognized as the appropriate size for this application, aligning with NEC requirements for safety and performance.
