Marinco 6373EL 50 Amp 125/250V Stainless Steel Shore Power Inlet, Round, Male, No Enclosure

The Marinco 6373EL is a 50 amp, 125/250 volt shore power inlet built for boats that need a reliable, corrosion-resistant connection point for dockside AC power. The body is solid cast 316 stainless steel, the marine-grade alloy chosen for its resistance to salt spray and harsh marine environments, so the inlet holds up to long-term outdoor exposure without pitting or corroding. It is a round, male plug-type inlet with a 4-wire, 4-pole configuration, matching the wiring standard used by 50 amp, 125/250 volt shore power cord sets.

A heavy-duty cap strap is built into the design for added strength and durability, keeping the protective cap secured to the inlet housing over years of use. This version of the 6373EL is supplied without a rear safety enclosure, so it is intended for installations where the inlet is mounted through a panel or bulkhead that already provides backside protection, or where an enclosure will be sourced separately. Marinco engineers its shore power hardware to be straightforward to install and use for both marine professionals and recreational boat owners, with a design that supports quick, secure dockside hookups.
