→ 30A Generator Cord L5-30P to TT-30R – 20 ft, 10 AWG
Free U.S. shipping & free 30-day returns — plus 10% off your entire order with code RVSAFE10.
Running your camper off a generator needs one specific cable: an L5-30P to TT-30R cord. The twist-lock L5-30P end locks into the generator's 30-amp outlet so vibration can't shake it loose; the TT-30R end is the standard RV receptacle your camper's 30-amp plug goes into. Here's how the popular options compare — and how to avoid buying the wrong cord.
Get the plug types right first
- L5-30P: 3-prong twist-lock, 30A 125V — the generator end.
- TT-30R: the “Travel Trailer” 30A receptacle — accepts a standard 30A RV plug. Not the same as a household dryer outlet, despite the resemblance.
- Wire gauge: 30 amps needs 10 AWG copper. Thinner wire runs hot and drops voltage — hard on air conditioners.
The RV Parts Giant cord
Our 20-foot generator cord is exactly this format: L5-30P twist-lock to TT-30R, heavy 10 AWG 3-conductor copper in a high-visibility yellow jacket, with weather-resistant molded ends and strain relief. Twenty feet is enough to park the generator away from the camper door without coiling excess cable — and it ships free with free 30-day returns.
Westinghouse
Westinghouse's 25-foot L5-30P to TT-30R cord is the same concept with five more feet — an honest pick if your generator needs to sit farther from the rig. Buy the length you actually need: extra cable is extra voltage drop and extra weight in the pass-through.
CircleCord
CircleCord's L5-30P to TT-30R adapter cords are ETL-listed with 10 AWG STW jacketing — a solid like-for-like alternative from a dedicated cord brand.
Champion
Champion's popular 48034 cord is a different tool: it splits the generator's L5-30 outlet into three 120V household outlets. That's great for powering tools or appliances at a worksite — but it is not an RV cord; there's no TT-30R end for your camper's plug. Don't buy it by mistake for shore power.
Bottom line
Need 25 feet? Westinghouse. Powering household gear off the generator instead of an RV? Champion's splitter. Connecting a 30-amp camper to a generator — the job most people are actually shopping for — our 20 ft 10 AWG cord does it with free shipping and free 30-day returns, shipped from our Upland, CA warehouse.
FAQ
Can I plug this into a campground pedestal? No — pedestals have the TT-30R built in; you plug the camper's own cord straight in. This cord is specifically for generators with an L5-30 twist-lock outlet.
Will it run my air conditioner? The cord carries the full 30A/125V. Whether the A/C starts depends on your generator's wattage, not the cord.
What if my generator only has household outlets? Then it can't feed a 30-amp camper properly — you'd need a generator with a 30A outlet (L5-30 or TT-30).
