Q: What is the ProMariner ProSafe FAILSAFE 60 Amp Galvanic Isolator (Model 22074)?
A: A heavy‑duty marine 60 Amp FailSafe galvanic isolator engineered to reduce corrosion by interrupting unwanted galvanic currents on your boat’s AC shore power ground without compromising safety ground continuity. It’s designed for boats connected to shore power (up to one 50 A cord or two 30 A cords).
Q: What does FailSafe technology mean?
A: FailSafe ensures that if the isolator fails, it still maintains AC safety ground continuity — so the electrical safety ground isn’t lost during a failure. It does not require a separate monitor to verify operation like non‑FailSafe devices.
Q: How does this isolator protect my boat?
A: It interrupts galvanic current flow between your boat and other boats or the dock while plugged into shore power, helping protect underwater metals like outdrives, props, and hull fittings and reducing excessive anode (zinc) loss.
Q: What shore power systems is it compatible with?
A: Suitable for 50 A shore power systems or dual 30 A shore cords, making it ideal for larger vessels and AC shore installations.
Q: Why choose this galvanic isolator?
A: It combines FailSafe protection, robust construction, and certified marine electrical safety — helping extend the life of underwater metals and reduce corrosion while keeping AC shore power systems safe and compliant.
