- (a) A distribution panel to which the generator leads are connected, and from which the electric leads throughout the vessel directly or indirectly receive their electric power is a switchboard.
- (b) Each switchboard must have a driphood or an equivalent means of protecting against falling liquid.
- (c) Nonconductive deck materials, mats, or gratings must be provided in front of each switchboard.
- (d) If the switchboard is accessible from the rear, nonconductive deck material, mats, or gratings must be provided in the rear of the switchboard.
- (e) Metal cases of instruments and secondary windings of instrument transformers must be grounded.
- (f) Each switchboard must be placed in a location that is accessible, adequately ventilated, and as dry as practicable. All uninsulated current carrying parts must be mounted on nonabsorbent, noncombustible, high dielectric insulating material.
- (g) Each switchboard must be of the dead front type.
- (h) Each switchboard must have front and, if accessible from the back, rear non-conducting hand rails except on vessels where the surrounding bulkheads and decks are of an insulating material such as fiberglass or wood.
