It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.\u003c\/p\u003e\u003cp\u003eSafety is taken for granted in the case of a normal onshore installation. A circuit breaker or a GFCI (Ground-Fault Circuit Interrupter) will trip in the event of a short circuit or current leakage to ground. Connecting the ground wire of the shore-side supply to the metal parts of the boat will result in galvanic corrosion (see below). Bringing only the live and neutral wire on board results in an unsafe situation because GFCIs will not work, nor will a fuse blow in case of a short circuit to a metal part on the boat.\u003c\/p\u003e\u003cp\u003eGalvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more active alloy of the couple corrodes preferentially while the less active (more noble) material is cathodically protected. The rate of galvanic corrosion is a function of several variables including area ratios, conductivity of the fluid, temperature, nature of the materials, etc.\u003c\/p\u003e\u003cp\u003eIt is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore -side supply.\u003c\/p\u003e\u003cp\u003eIt might therefore be tempting not to connect the ground conductor: this is however e xtremely dangerous because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.\u003c\/p\u003e\u003cp\u003eThe best solution to avoid galvanic corrosion and at the same time prevent any uns afe situation is to install an Isolation Transformer to connect to the shore-side supply.\u003c\/p\u003e\u003cp\u003eThe Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary.\u003c\/p\u003e\u003cp\u003eThe Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit.\u003c\/p\u003e\u003cp\u003eSoft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from blowing due to the inrush current of the transformer, which would otherwise occur.\u003c\/p\u003e\u003cp\u003eIt is also recommended, for optimal safety, to connect the secondary neutral of the transformer to ground when the boat is out of the water.\u003c\/p\u003e\u003cp\u003e4500 Watt Auto 115\/230 V - This model will automatically switch to 115 V or 230 V supply, depending on input voltage.\u003c\/p\u003e\u003cp\u003eSupply 88 V  130 V: switches to 115 V supply\u003c\/p\u003e\u003cp\u003eSupply 185  250 V: switches to 230 V supply range.\u003c\/p\u003e\u003cp\u003eNote: The AC input voltage is raised by 1:1.05 ratio at the AC output.\u003c\/p\u003e\u003cstrong\u003ePlease contact your dealer for any returns, repairs or support issues related to this product.\u003c\/strong\u003e \u003c!--- cis2:m2lsl5xp ---\u003e\n\u003cp\u003eThe Victron Energy 4500W Auto Isolation Transformer (Part Number: ITR050452042) is an essential component for ensuring electrical safety and protecting your boat from galvanic corrosion. Designed to automatically switch between 115V and 230V power supplies, this transformer provides a reliable and safe connection between shore power and your vessel. Its primary function is to eliminate electrical continuity between the boat and shore power, reducing the risk of galvanic corrosion that can damage metal components like shafts and propellers. By isolating the boat's electrical system, it prevents the electrochemical reactions caused by seawater and freshwater exposure, thereby extending the lifespan of your metal parts and sacrificial anodes.\u003c\/p\u003e\u003cp\u003eThe transformer features a built-in soft-start mechanism that minimizes inrush current, preventing fuse blowouts and protecting your electrical system during startup. It offers seamless voltage switching, automatically adapting to input voltages ranging from 88V to 130V for 115V operation and 185V to 250V for 230V operation, ensuring stable power delivery regardless of shore supply fluctuations. For enhanced safety, it is recommended to connect the secondary neutral to ground when the boat is out of water, providing an additional layer of protection and grounding stability. The transformer’s compact design, with dimensions suitable for marine installations, makes it a versatile and reliable choice for boat owners seeking to safeguard their electrical systems.\u003c\/p\u003e\u003cp\u003eConstructed by Victron Energy, a trusted name in marine and power management solutions, this 4500W auto isolation transformer is a crucial upgrade for any vessel.
