Best RV Shore Power Cords
Compare 30-amp and 50-amp RV power cords by inlet style, plug geometry and hardwired versus detachable installation.
Compare Current OptionsShore power cords look deceptively similar, but a wrong connector can mean no power—or a hazardous attempt to force a mismatched hookup. Before comparing handles, cable flexibility or price, determine whether your RV uses a 30A or 50A service and whether the cable is detachable or hardwired. This guide focuses on replacement cords rather than the adapter choices covered separately.

01 Shore power shortlist
Four distinct cord configurations cover the most important decisions: 30A versus 50A, straight versus angled, and detachable versus hardwired.
A detachable 25-foot cord for a 30-amp RV with a twist-lock inlet and standard 30-amp campsite pedestal.
This 30-amp 25-foot detachable cord adds 90-degree connector geometry to reduce cable strain in cramped RV inlet locations.
A 25-foot detachable 50-amp shore cord with angled connectors, pull handle and an RV-end power indicator.
A replacement 30-amp shore cord for RVs whose cable is permanently hardwired instead of connected to a detachable inlet.
02 Compare connector configurations
All four products are 25 feet long, but they are not interchangeable. Verify inlet and pedestal geometry before buying.

Check Price04 Seven shore-power safety checks
Connector compatibility and pedestal safety matter more than a cord’s color or advertised convenience features.
- Identify the RV electrical service: Check the RV data plate, inlet and electrical documentation. A 30A RV typically uses 120V TT-30 service; a 50A RV typically uses 120/240V split-phase service.
- Inspect both connector faces: Compare blade pattern and locking style at the RV inlet and campground pedestal. Similar-looking plugs are not interchangeable.
- Distinguish detachable from hardwired: A twist-lock detachable cord cannot directly replace a cord wired into the distribution panel, and a hardwire cable cannot simply plug into an RV inlet.
- Choose sufficient but not excessive length: Measure the likely pedestal-to-inlet route without stretching or crossing traffic; long cords add bulk and potential voltage drop.
- Check the complete cord condition: Reject melted plugs, corrosion, cracked insulation, loose blades and warm or discolored connectors. Never repair a damaged shore cord with tape.
- Keep connections dry and strain-free: Follow manufacturer guidance for weather protection and secure locking rings; do not place plug junctions in standing water.
- Verify the pedestal before energizing: Use an appropriately rated RV surge protector or electrical management system to detect common pedestal faults and shut off power before connecting or disconnecting.
05 Start with the RV inlet
30A detachable inlet? Choose a matching 30A twist-lock cord; consider the 90-degree A10-3025ED90 when clearance is tight.
50A detachable inlet? Use a properly rated 50A cord with the correct RV locking connector and four-prong pedestal plug, such as A10-5025ED90 where compatible.
Original cord hardwired? Replace with a cord designed for hardwired installation and have a qualified RV electrician verify termination and strain relief.
Only a different campground outlet available? That is an adapter question, not a reason to buy an incompatible cord. See RV 30A-to-50A adapter guidance when the separate guide is published. A surge protector or electrical management system may help detect unsafe pedestal wiring.
06 Frequently asked questions
Can I use a 50-amp cord on a 30-amp RV?
Not directly. Connector patterns and the RV electrical service differ. Use only a properly rated and approved adapter where compatible; an adapter cannot increase the RV’s service capacity.
Is a 30-amp RV cord the same as a household dryer cord?
No. A TT-30 RV receptacle is a 120V configuration, while common dryer connections use different voltage and wiring. Never adapt by appearance alone.
Do I need a twist-lock or hardwired shore cord?
Check whether the RV has a removable inlet or a permanently attached cable. Detachable twist-lock cords and hardwired replacements are different products.
Is a 25-foot RV power cord long enough?
Often, but it depends on where the pedestal sits relative to the RV inlet. Measure typical campsite layouts and avoid taut connections.
Why does a shore power plug get hot?
Loose or corroded contacts, overloaded circuits and poor connections can generate dangerous heat. Disconnect power safely and have the fault inspected rather than continuing to use a hot plug.
Does a 50-amp RV cord provide 50 amps total?
A typical 50A RV hookup has two 120V hot legs rated up to 50A each, unlike a 30A 120V RV service. Actual usable power depends on the RV system and pedestal; do not confuse the plug with an adapter’s capacity.
07 Match the plug before the price
Buy a shore power cord only after confirming the RV’s service rating, inlet style, pedestal plug and installation type. A 25-foot cable with convenient handles is useful only when its electrical connectors are the correct ones; adapters and extensions solve different problems.
Cord connector compatibility
A 30-amp TT-30 connection and a 50-amp 14-50 connection are not interchangeable. Even within the same amperage, detachable twist-lock RV inlets and hardwired cord ends require different products. Match the RV inlet, campground pedestal and cable rating before ordering.
