Marinco M4100P12 100A 125/250V Shore Power Plug

The Marinco M4100P12 is a 100A 125/250V shore power plug, mating with the M4100R12 receptacle.

One hundred amps is heavy shore service, well above the 30 and 50 amp connections most boats use, and the components are not interchangeable with lower-capacity marina hardware. Matching the plug to the correct receptacle family is what maintains both the mechanical fit and the electrical configuration, so the model relationship matters more here than on a smaller connector.

The plug is intended for building or repairing a shore power assembly where the cable is still serviceable but the plug end needs replacing. At this capacity a cordset is expensive enough that replacing an end rather than the whole assembly is worth doing properly.

It mates specifically with the M4100R12 receptacle rather than any 100A fitting, so the receptacle should be identified before ordering. This is installer-level hardware for larger vessels with high-capacity AC service rather than a recreational shore connection. Explore more shore power connectors.
