Safeshore Marine Galvanic Isolator 100A ⚓

This galvanic isolator offers dependable protection for boats connected to shore power, helping to control galvanic and stray currents that can corrode submerged metals. It is aimed at owners who need a straightforward, high-capacity device to protect anodes, hull fittings, shafts and propellers, with clear performance figures according to the manufacturer. This unit helps maintain underwater hardware integrity while berthed and during short stays on shore power.

Key Points

The isolator prevents destructive stray currents from reaching underwater metalwork, which can slow corrosion and reduce maintenance needs. It operates without interrupting the neutral return path, so shore power functionality remains intact while protection is active. Many users value its simplicity and the fact that installation is usually compact and near the inboard power connection. ⚓

Longevity is a core attribute. The unit monitors and controls parasitic currents and galvanic flow continuously, so metal sacrificial anodes are better preserved and fittings suffer less electrochemical damage. For operators who spend extended periods alongside quays, this presents a practical way to limit cumulative metal loss. 🔧

Usage Recommendations

Fit the isolator in the shore power return line as close to the vessel distribution panel as practical, following marine electrical regulations and manufacturer guidance. Allow an electrician with marine experience to perform the installation, as correct bonding and earthing arrangements are essential for safety and effect. ⚠️

Consider that galvanic isolators reduce galvanic corrosion but do not replace routine inspection of anodes or sacrificial protection. In mixed-metal installations or where stray current sources are significant, additional monitoring or supplementary systems may be advisable according to the manufacturer.
