Code of Federal Regulations Title 46. Shipping § 46.111.50–5 Location of overcurrent protective devices

(1) The generator overcurrent protective device must be on the ship's service generator switchboard. (See § 111.12–11(g) for additional requirements.)

(2) The overcurrent protection for the shore connection conductors must meet § 111.30–25.

(3) If the overcurrent device that protects the larger conductors also protects the smaller conductors, an overcurrent device is not required at the supply to the smaller conductors.

(4) If the overcurrent device protecting the primary side of a single phase transformer (two wire with single-voltage secondary) also protects the conductors connected to the secondary side, as determined by multiplying the current-carrying capacity of the secondary conductor by the secondary to primary transformer voltage ratio, and this protection meets § 111.20–15 of this chapter, an overcurrent device is not required at the supply to the secondary side conductors.

(1) Must be:

(2) Must not be:
