RV Shore Power Cables

Your camper most likely came with the main power cable, but having a back-up is proper planning. If it did not come with a cable, you’d need at least one of these to power your RV (20, 30, or 50 Amp).

Pro Tip: Select a back-up cable you can use as an extension if needed.   

Larger RV’s typically use 50 Amp cables.
