30 Amp RV Power Cords, Extension Cords and Accessories

What is a 30 amp RV power cord used for?

A 30 amp RV power cord connects your rig to a 30A/120V shore power pedestal at campgrounds, RV parks, and home outlets wired with a TT-30 receptacle. It carries up to 3,600 watts, enough to run a single 13,500 or 15,000 BTU air conditioner along with lights, the converter charger, and smaller 120V loads. If your pedestal only has a 50A or 15A outlet, you will need an adapter, see our RV plug adapters collection for the correct dogbone.

What length of 30A RV extension cord do I need?

Most owners keep a 25-foot or 30-foot 30A extension cord on board, which covers the gap when the pedestal sits farther from the rig than your built-in cord reaches. For driveway hookups or back-in sites with awkward pedestal placement, a 50-foot cord gives more flexibility. Voltage drop becomes a concern past 50 feet on a fully loaded 30A circuit, so size up the rest of your shore power setup before extending further.

Can I plug a 30 amp RV cord into a 50 amp outlet?

Yes, with the right adapter. A 50A to 30A dogbone adapter lets you draw 30 amps from a 50A pedestal safely, your RV will still be limited to its 30A service rating. Do not wire a homemade adapter or swap the cord end, the molded plug is rated for the amperage and weather exposure it sees at the pedestal. Pair your cord with a surge protector to guard against pedestal miswiring and high or low voltage events.

Are these cords compatible with my RV?

Any RV wired for 30A service uses the same TT-30P plug standard, so the cords in this collection fit travel trailers, fifth wheels, Class C motorhomes, and smaller Class A coaches with 30A shore power inlets. Confirm whether you need a detachable cord (with a male plug on both ends and a twist-lock or straight blade inlet connector) or a hardwired replacement that runs directly into the RV's power center. Text or call our team at 817-984-1852 if you need help confirming the right configuration.

Do you offer free shipping on 30 amp RV power cords?

Yes, orders over $100 ship free within the contiguous US, which covers most 25-foot and longer 30A cords along with adapter bundles. Smaller accessory items ship at standard rates. While you are setting up your electrical kit, take a look at the Coleman RV air conditioner soft start collection, a soft start kit reduces inrush current and helps a 30A service handle your AC startup without tripping the pedestal breaker.
