   The electrical panel is custom built with 12 and 120 volt circuit breakers. Two engine alternators provide charging capacity of over 100 amps. Four heavy duty marine batteries are equipped, with a 12 volt 40 amp battery charger. There is a 120 volt 50 amp shore power cable as well.

   DC links are ideal for this, but cannot be safely deployed without the necessary protection. Proper selection of protective devices (such as a DC breaker switch, high-speed fuse, or a circuit breaker) and their allocation according to distribution protection zones enables system integrators to achieve protection selectivity.

4. Motorboating (electronics) - Wikipedia

   en.wikipedia.org/wiki/Motorboating_(electronics)

   In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.

5. Shunt (electrical) - Wikipedia

   This will cause both an immediate drop in voltage (protecting the device) and an instantaneous high current which is expected to open a current sensitive device (such as a fuse or circuit breaker). This device is called a crowbar as it is likened to dropping an actual crowbar across a set of bus bars (exposed electrical conductors).

6. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   [12] A large power circuit breaker, such as one applied in circuits of more than 1000 volts, may incorporate hydraulic elements in the contact operating mechanism. Hydraulic energy may be supplied by a pump or stored in accumulators. These form a distinct type from oil-filled circuit breakers where oil is the arc-extinguishing medium. [13]
