Marinco M4100C12 100A 125/250V Shore Power Connector

The Marinco M4100C12 is a 100A 125/250V shore power connector for extension cords and adapter assemblies.

The important restriction is that this connector does not mate with a boat's shore power inlet. It is the female end of an extension cord or adapter, mating with a plug rather than with an inlet. Marinco's high-capacity range includes several connection types that look similar and serve different roles, so the mating component should be identified before ordering rather than after.

It suits building a purpose-made shore power extension, or replacing a connector end where the cable itself is still in good condition. At 100 amps a cordset represents enough money that replacing one end rather than the whole assembly is worth doing with the correct part.

One hundred amp service is well above the 30 and 50 amp connections most boats use, and the hardware is not interchangeable with those. This is installer-level equipment for larger vessels with high-capacity AC service rather than a recreational shore connection. Explore more shore power connectors.
