# §169.666. Generators and motors.

- (a) Each vessel of more than 65 feet in length having only electrically driven fire and bilge pumps must have two generators. One of these generators must be driven by a means independent of the auxiliary propulsion plant. A generator that is not independent of the auxiliary propulsion plant must meet the requirements of [§ 111.10-4(c)](/cfr/46/111.10-4.md?p=c) of this chapter.
- (b) Each generator and motor must be in a location that is accessible, adequately ventilated, and as dry as practicable.
- (c) Each generator and motor must be mounted as high as practicable above the bilges to avoid damage by splash and to avoid contact with low lying vapors.
- (d) Each generator must be protected from overcurrent by a circuit breaker, fuse or an overcurrent relay.
