Shore power
Shore power on yachts: AC inlet, isolation, and FairHelm survey checks for earthing faults and cable condition.
这是什么
Shore power is marina AC electricity brought aboard through an inlet, shore cable, and onboard distribution, often charging batteries and running heaters.
Anchor
Nordic winters mean long shore-power stays. FairHelm notes inlet heat damage, cable condition, RCD/breaker presence, and whether a galvanic isolator or isolation transformer is fitted.
FairHelm judgment
FairHelm judgment: cheap long-term shore power without isolation can accelerate anode loss. Treat mystery earth faults and warm inlets as survey items, not minor electrics.
Limits
We do not invent marina voltage standards per country here. Confirm local plug type and boat wiring with a marine electrician when unsure.
常见问题
Q: Does shore power replace a battery bank?
A: No. It charges and supplies AC. Off-grid still needs batteries.
Q: Is a galvanic isolator mandatory?
A: Strongly advisable on metal underwater gear with long shore stays. Confirm for your hull metals.
Q: Can a warm inlet be normal?
A: Slight warmth can occur under load. Hot, discoloured, or melted plastic is a fail.
