Help protect your boat’s bonding system and shore-power safety ground with the ProMariner ProSafeFS Galvanic Isolator. Built for marina environments, the ProSafe FS Series interrupts galvanic current flow from other boats while helping maintain AC safety ground continuity when connected to AC shore power.
Key Features
- Interrupts galvanic current flow with other boats at a marina when installed on a boat connected to AC shore power
- Helps maintain AC safety ground and addresses common corrosion sources associated with bonding system galvanic action
- ProSafe FS Series is UL Certified and ABYC A-28 recommended for FailSafe installations
- Built on Flat Pack semiconductor platforms designed so that, in the event of a failure, ground continuity is not compromised while connected to AC shore power
- Designed for FailSafe operation—does not require a dedicated monitor to verify operational status (unlike non FailSafe Certified galvanic isolators)
- Meets FailSafe criteria for inrush current conduction (FS30 meets the 3,000A FailSafe criterion)
Intended Use
- Shore power electrical systems using an onboard AC inlet/AC panel ground and DC bonding system separation
- Marine boats requiring galvanic isolation to help reduce corrosion and premature zinc loss in marina conditions

Parts Desk Insights
Best Use Case: Best for boats that spend time on AC shore power at marinas and want galvanic isolation while helping preserve AC safety ground continuity as part of their shore-power/bonding system setup.
Common Issues: Installation depends on correct placement in the system (between the AC inlet and your AC panel green safety ground path as part of ground separation). If you experience unexpected corrosion or shore-power grounding issues, confirm wiring/termination points and review the installation diagram for the FS Series you’re using.
