Different Connectors Used on 50-Amp RV Extension Cords versus 50-Amp Power Cords

Question:

Is there a difference between a 50 amp rv power cord and a 50 amp extension cord? I need a cord from my 5th wheel to the power source

We offer 50-amp-rated power cords for RVs for connection to generators and to shore power at a campground. Extension cords can have the same current capacity but will have different connectors since they are intended to just match the existing ones to extend your connection length. Extension typically have a male and female connector of the same type.

You can refer to the linked page to see all of our RV wiring items, including adapter plugs, adapter cords, power cords, extension cords and power inlets.

For instance, part # A10-5050EH is 50-foot extension cord with 4-prong 50-amp male and female plugs. I included a photo for you to show the two connectors, both of which are NEMA 14-50 type.

A power cord to connect the RV to a shore power source will have two different connectors on it, one to mate with the RV inlet and one to mate with the shore power source outlet. A part like # A10-5025ED90 that you referenced has one of the NEMA 14-50 male plugs on the source end and a female twist-lock connector on the RV end.
