Camco 55255 50A Power Grip Replacement Plug 14-50P

The plug end takes the most abuse on any shore power cord. It gets yanked out at an angle, dragged across the dock, stepped on, and left sitting in the weather. Over time the prongs corrode or the housing cracks, and a bad plug is both a hassle and a real safety problem. This Camco Power Grip 55255 replacement plug lets you cut off the damaged end and wire on a fresh one, so a small part saves you from buying a whole new 50 amp cord.

Replacing the plug instead of the whole cord is the practical call most of the time. Fifty amp cords aren't cheap, and there's usually nothing wrong with the wire, it's just the end that failed. Cut off the bad plug, wire on this one, and the cord is back in service. You keep good copper out of the landfill and money in your pocket.

It's a 50 amp NEMA 14-50P male plug, the four-prong configuration used on 50 amp RV and boat shore power. Two hots, one neutral, one ground. Camco rates it for 125/250 volts and up to 12,500 watts, which is the full load a 50 amp service delivers. That rating matters. Undersize a plug or a cord on a 50 amp circuit and you get heat at the connection, so pair this with a proper 50 amp cord and you're set.

The molded plug head handle is the reason people reach for the Power Grip line. Instead of pulling on the cord to break the plug free from a tight pedestal or inlet, you grab the handle and pull straight back. That's easier on your hands, and it's easier on the prongs and the wire terminals inside. Pulling on the cord itself is what wrecks most plugs in the first place, so the handle isn't just comfort, it's what makes the plug last.

Wiring it on is straightforward if you're comfortable with basic AC work. Kill the power at the pedestal first, every time. Strip the cord jacket back, land each conductor on its matching terminal, hot to hot, neutral to neutral, ground to ground, and snug down the strain relief so the cord can't pull loose. Follow the layout printed in the package for the exact terminal positions. If you're not confident working around 240 volt AC, have a marine electrician or an RV tech handle it. For someone who does this regularly it's a ten minute job.

One thing worth checking before you start. A 50 amp cord uses heavy copper conductors, and the terminals in this plug are sized for that gauge of wire. Make sure your cord's wire matches what a 50 amp circuit calls for. If someone spliced thinner wire in somewhere down the line, sort that out too, because the plug is only as safe as the cord behind it.

This is the plug end only. It's designed for Camco Power Grip 50 amp power cords, and it'll wire onto any standard 50 amp cord with the correct conductor gauge. It doesn't come with cord, a receptacle end, or spare gaskets, so if your cord is chewed up on both ends you'll want the matching receptacle too.

Fifty amp shore power is the same standard whether you're at a marina pedestal or an RV park post, so this plug works for both. After you wire it on, do a quick polarity check before you trust it. A reversed hot and neutral can trip the GFCI on a lot of shore power pedestals, and it's worth catching that on the bench instead of at the slip. Keep the connection dry, seat the plug fully into the inlet, and don't leave it hanging in a puddle.

It ships in a clamshell package, one plug, in bright yellow so it stands out in a locker full of black cordage. It's a smart spare to keep aboard. A cracked plug always seems to happen on a Friday night when nothing's open, and having the fix on hand beats sitting at the dock with no power.
