RV power adapter 30A to 50A

This adapter connects a recreational vehicle 50A four-prong cord to a 30A three-prong campground outlet. It is built for RV hook-up use only and is not intended for electric vehicle charging. The unit supports a maximum load of 30 amps at 125 volts.

Check your RV cord and site outlet

Verify that your RV power cord ends in a 14-50P four-prong plug and that the campsite pedestal provides a TT-30R three-prong 30A 120V receptacle. The adapter is rated for 30A maximum loading, so total appliance draw must stay within that limit. Ensure the voltage at the site matches the 125V rating before connecting.

Heavy-duty construction and daily use

The body uses black PVC housing with 100% copper conductors inside for reliable current transfer. A round, one-piece design resists strain when plugged into a pedestal and reduces the chance of loose pins. The straight blade TT-30P male plug and 14-50R female receptacle lock together securely for stable power during travel stops.

Questions about this item

What comes in the box and does the adapter include any extra cables or mounting hardware?

The box contains the single 691647 adapter with a TT-30P male plug and a 14-50R female receptacle; no additional cords or mounting parts are supplied.

How do I know whether the 30 A 125 V rating or the 50 A receptacle rating applies to my RV hook-up?

The adapter is limited to 30 A and 125 V, so the 14-50R socket can only pass 30 A even though it accepts a 50 A plug.

What does the 3750 W figure mean when I plug the adapter into a campground pedestal?

At 125 V the 30 A limit gives a maximum of 3750 W, so any load above that will trip the pedestal breaker.
