Power supply.

Each steering failure alarm system must be supplied by a circuit that: (a) Is independent of other steering gear system and steering alarm circuits; (b) Is fed from the final emergency power source through the emergency distribution panel in the wheelhouse, if installed; and (c) Has no overcurrent protection except short-circuit protection by an instantaneous fuse or circuit breaker rated or set at 400 to 500 percent of: (1) The current-carrying capacity of the smallest alarm system interconnecting conductors; or (2) The normal load of the system.
