Marinco 100A Inlet - 125/208V

The Marinco 100A Inlet 125/208V (Model M5100B9R) is a professional-grade shore power connector designed for marine vessels requiring three-phase electrical input at 120/208 volts. Built from gray Amalast polymer, this 100-amp inlet withstands the harsh marine environment while maintaining a secure, watertight connection to onboard electrical systems. The gasketed, spring-loaded cover design delivers IP67 waterproof protection, meaning it safely handles temporary immersion without compromising internal contacts or electrical integrity.

This inlet is configured as a 4-pole, 5-wire system rated for 100 amps at 3-phase Y120/208 voltage—the standard configuration for modern marine shore power pedestals and land-based power facilities. The 100-amp capacity supports substantial onboard loads including multiple air conditioning units, galley equipment, water heaters, and auxiliary systems simultaneously without voltage drop or circuit limitation. The spring-loaded cover mechanism ensures the connector remains protected when not in use, preventing salt spray, rain, and debris from degrading terminal surfaces and electrical conductivity.

Serious cruisers, commercial fishing operations, and vessel owners who spend extended time at dock benefit most from this inlet's robust engineering. The Marinco 100A Inlet serves vessels transitioning between mobile power generation and shore-based electrical systems, particularly in saltwater environments where corrosion and water exposure demand corrosion-resistant materials and sealed electrical connectors. Installation typically requires permanent mounting to the vessel's exterior hull or electrical cabinet, with internal wiring handled by qualified marine electricians to ensure code compliance and system safety.
