Onboard Power Systems

Do you need electricity? These days, a harbour master's question is usually answered in the affirmative, because electricity consumption on boats has increased considerably. Taking shore power, the question is, through which parts of the on-board electrical system the current flows. If the shore power cable is plugged in, on some yachts it is connected to a shore power unit protected by a FI/LS-circuit breaker. On steel ships, a galvanic insulator that protects against corrosion caused by galvanic currents may be located in between. Next is a marine charger, …

… connected to the onboard batteries. If more batteries need to be charged, a battery isolator may be fitted. Now it comes to the main onboard electrical system with 12V or 24V voltage. The batteries can be disconnected from the on-board electrical system by a battery main switch. A circuit breaker or a switch panel divides the circuit into single circuits. These panels have buttons or switches including fuses for respective consumers. At Toplicht you will find everything you need for electrical installation. Our HNA switches, plugs and sockets made of heavy brass have a special robust design that is perfect for traditional ships and motor vessels. They have been used in commercial shipping and navy for decades and are in part tested by German classification society GL.
