The Marinco 30MPRV is the yellow replacement plug that wires onto your existing 10-gauge cable. It's a NEMA TT-30P male end with solid brass blades and a glass-filled nylon body built to take weather and rough dock handling.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eShore power cords take a beating. They get dragged across the dock, stepped on, run over by a dock cart, and left plugged in through every kind of weather. Sooner or later the plug end is the part that goes. You'll see a cracked housing, a blade that's gone dark with corrosion, or a scorch mark that tells you a loose connection has been arcing. When that happens, the good news is you don't have to throw away a perfectly good cord. You cut off the bad end and wire on a new one.\u003c\/p\u003e\n\u003cp\u003eThat's exactly what the Marinco 30MPRV is for. It's a 30-amp male replacement plug that fits 10-gauge cordage, the standard wire size for a 30-amp shore power cord. The three blades follow the NEMA TT-30P pattern, which is the same configuration you'll find on every standard 30-amp RV pedestal and marina power post. Wire it on correctly and it drops right into the outlets you already use.\u003c\/p\u003e\n\u003cp\u003eThe build is what you want in a part that lives outside. The housing is glass-filled nylon, which shrugs off UV, salt spray, and the odd knock against a piling far better than plain plastic. The blades are solid brass, so you get a solid, low-resistance connection at the outlet instead of the heat and voltage drop that comes from a corroded or undersized contact. And there's a real strain relief built into the body that clamps down on the cable jacket, so the weight of the cord and the tug of the wind aren't pulling on your wire terminations.\u003c\/p\u003e\n\u003cp\u003eThe wide grip handle is a small thing that matters more than you'd think. A 30-amp connection holds tight in the outlet by design, and on a cold morning or with wet hands, a plug you can actually grab makes disconnecting a one-hand job instead of a wrestling match. Pull on the handle, not the cord. That habit alone will make any plug last longer.\u003c\/p\u003e\n\u003cp\u003eWiring one up is straightforward if you've done any 120-volt work. You've got three conductors: hot, neutral, and ground. Strip the jacket back, land each wire on its marked terminal, snug the set screws down firmly, and seat the cable in the strain relief before you close the housing. Give each screw a second tug to confirm it's tight, because a loose terminal is the number one cause of a burnt plug. If you're not comfortable working with AC wiring, have an ABYC-savvy tech or a qualified electrician do the terminations. It's a ten-minute job for someone who does it regularly.\u003c\/p\u003e\n\u003cp\u003eThis plug works for both marine and RV use, which is why you'll see it on boats and campers alike. Anywhere you've got a 30-amp, 120-volt shore power cord with a TT-30P end, this is the plug. It's the male end that goes into the dock or pedestal outlet. If the connector on the boat side of your cord is the part that failed, that's a different piece, so check which end you actually need before you order.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about: this is the plug only. It doesn't come with cordage or wire. You're wiring it onto the cord you already own. If your cord's copper is corroded green well up inside the jacket, or the insulation is cracked and brittle, replace the whole cord instead. A fresh plug on tired wire just moves the problem. But if the cable itself is sound and only the end is damaged, a 30MPRV gets you back in service for a fraction of the cost of a new cord.\u003c\/p\u003e\n\u003cp\u003eKeep one in the dock box. Plug ends fail at the worst times, usually right when you're trying to get power to the fridge or the battery charger, and having the replacement on hand means a quick fix instead of a lost weekend.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eNEMA TT-30P 3-prong male configuration drops straight into standard 30-amp RV pedestals and marina power posts\u003c\/li\u003e\n  \u003cli\u003eFits 10-gauge (10 AWG) cordage, the standard wire size for a 30-amp shore power cord\u003c\/li\u003e\n  \u003cli\u003eSolid brass blades deliver a low-resistance connection that runs cooler at the outlet\u003c\/li\u003e\n  \u003cli\u003eGlass-filled nylon housing resists UV, salt spray, and impact for long life on the dock\u003c\/li\u003e\n  \u003cli\u003eIntegrated cord strain relief clamps the cable jacket so tension never pulls on your wire terminations\u003c\/li\u003e\n  \u003cli\u003eWide grip plug-head handle makes disconnecting easy with cold or wet hands\u003c\/li\u003e\n  \u003cli\u003eRated for a full 30 amps for both marine and RV shore power\u003c\/li\u003e\n  \u003cli\u003eYellow high-visibility body is easy to spot in a crowded dock box or a dim slip\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Marinco reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size cord does the Marinco 30MPRV fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's built for 10-gauge (10 AWG) cordage, the standard wire size for a 30-amp shore power cord.
