Camco 55242 Power Grip 30 Amp Replacement Plug TT-30P

This is the Camco Power Grip 55242, a replacement male plug for your 30 amp shore power cord. Here's the thing about cordsets: the copper in the middle almost always outlives the plug ends. The business end takes all the abuse. It gets yanked, dropped, stepped on, and slowly cooked by the heat of a loose connection. When that plug end finally cracks, melts, or the prongs won't hold a grip in the pedestal anymore, you don't have to throw away a perfectly good cord. You cut off the bad end and wire this one on.

The plug uses the NEMA TT-30P pattern, which is the standard 30 amp configuration you'll find on RV shore cords and most dockside power pedestals. It's the male end, so it's the half that plugs into the pedestal or into a 30 amp adapter. It's rated for 125 volts and 3750 watts, which is the full load a 30 amp circuit is built to carry. So you're not giving up any capacity by rewiring, you're just restoring the cord you already trust.

What sets the Power Grip line apart is right there in the name. The molded handle wraps the body of the plug and gives you something solid to hold onto. Anyone who's tried to pull a stiff, cold plug out of a tight pedestal knows the problem. You end up hauling on the cord itself, which is exactly what wears out the connection in the first place. The handle lets you push and pull on the plug body instead. On a boat that's rocking against the dock, or an RV site where the pedestal is mounted at an awkward height, that grip earns its keep every single time you hook up or break down.

Who's this for? Anybody with a 30 amp shore cord that's still got good wire but a tired plug. Look for the warning signs before it strands you: discolored or melted prongs, a plug that feels warm to the touch after an hour of use, cracks in the housing, or a loose fit that makes the connection flicker. Any one of those means it's time. Catching it early beats losing power to the fridge at 2 AM.

The install is straightforward if you're comfortable with basic DC and AC wiring, and it's a job most boaters and RV owners can handle at the dock. You'll want 10 gauge copper wire to match a 30 amp load, and the leads land on the hot, neutral, and ground terminals inside the plug. Take your time and get the polarity right. Reversing the hot and neutral is the most common mistake, and it'll trip the ground fault protection at the pedestal the moment you plug in. A dab of dielectric grease on the terminals before you button it up keeps corrosion out of the connection, which matters a lot in the salt air. Snug those set screws down firmly, and give them a re-check after your first season since vibration can back them off over time.

The housing is yellow polyvinyl, so it stays flexible in the cold and it's easy to spot on a dark dock or a crowded pedestal. It's cETLus listed, so the electrical safety has been verified by an independent lab. And it ships in bulk packaging, which is handy if you're repairing more than one cord or keeping a spare in the dock box for the fleet.

One thing to be clear on: this is the plug end only. It isn't a complete cordset, and it isn't a 50 amp plug. If you're running 50 amp service or you need a whole new cord, this isn't the part. But if you've got a solid 30 amp cord with a bad end, the 55242 is the fix, and it'll cost you a fraction of a new cord.
