Camco 55142 15-Amp 30-Ft RV Extension Cord

The Camco 55142 is a 30-foot, 15-amp extension cord built to close the gap between your rig and the power you need. Male NEMA 5-15P on one end, female NEMA 5-15R on the other. Standard three-prong household connections, so it plugs into the same outlets you already use at the campsite, the driveway, or the dock.

Here's the short version. It's rated for 125 volts and 1875 watts, wound in 14-gauge copper, and carries the cETLus safety mark. That's the same 15-amp circuit you'd find on a household outlet, just stretched out 30 feet so you can reach a pedestal or an outlet that's parked too far away. If your RV power supply cord won't quite make it, this is the cord that gets you there.

We reach for a cord like this all the time. Pulling into a site where the pedestal is on the wrong side. Running a battery charger and a small fridge off a distant garage outlet during storage. Powering household appliances, tools, or a shop light when the nearest receptacle is 25 feet away. The 55142 handles all of it as long as you stay inside the 15-amp, 1875-watt ceiling. Think chargers, fans, small heaters, lights, and power tools. Not a rooftop air conditioner and a microwave running at the same time.

A word on the wire. Fourteen-gauge copper is the right size for a 15-amp load, but any cord loses a little voltage over distance, and 30 feet is enough to notice if you're pushing near the top of the rating. If you're running a battery charger plus a fridge on a long run and the charger seems sluggish, that's voltage drop talking, not a bad cord. Keep the run as short as the layout allows and you'll be fine.

The safety habit that matters most is simple. Uncoil it. A cord left coiled while it's carrying a real load traps heat inside the loops and the jacket gets hot. Roll it out flat, or at least lay it in loose figure-eights, whenever you're drawing serious current. Costs you nothing and it's the single best thing you can do for a cord's lifespan.

The jacket is black PVC, which shrugs off scuffs, driveway grit, and the odd tire roll better than a thin cheap cord. It's an outdoor-rated cord for RV, mobile home, and household outdoor use. Keep the connections up off standing water and out of puddles. It's a dry-location outdoor cord at heart, not a submersible fitting, so treat the plug ends with the same respect you'd give any shore connection.

Boaters, this one earns a spot in the dock bag for smaller boats running off a 15-amp pedestal. It'll carry a charger, a couple of fans, and cabin lights on a 20-foot boat without complaint. Salt air is hard on any plug, so a little dielectric grease on the female end and a habit of drying the connection go a long way. If you're regularly loading an air conditioner or you're on a 30-amp inlet, step up to a proper 30-amp shore cord instead. Right tool, right job.

The cETLus mark means the cord has been tested and certified to recognized US and Canadian safety standards, so you're not guessing about the build quality. Combine that with the full-size copper conductors and standard three-prong ends, and you've got a cord that'll ride along season after season if you treat it right. Store it dry, coil it loosely for transport, and check the prongs now and then for looseness or discoloration.

Bottom line. If you need to reach power that's a little too far away, and your load lives inside 15 amps, the Camco 55142 is a straightforward, safety-certified 30-footer that does exactly what it says. No surprises. Just more reach.
