Marine shore power components

Marine shore power inlets, cables, breakers, and isolation hardware. A safe, ABYC-compliant shore power install is the foundation of everything else electrical on the boat — it's where the AC enters, where galvanic isolation happens, and where ELCI protection lives.

• SmartPlug 30A and 50A inlets — superior to twist-lock for marine environments
• Galvanic isolators — protect against stray-current corrosion
• Isolation transformers — full electrical isolation from shore
• GFI / ELCI breakers — leakage detection per ABYC E-11

For installation including 30A, 50A, and 100A shore power systems with proper grounding and isolation, see our marine shore power installation service page. Marine Electric Systems serves Annapolis, Baltimore, and the Washington DC area.
