Needed a way to connect my RV’s 30-amp outlet to my home’s transfer switch, and this little adapter does the job. Feels sturdy, plugs in securely, and no weird fit issues. The molded plug grips are perfect too so it's easy to plug and unplug.The cable itself is thick and flexible. Connections are snug. Ran it under load for a few hours, no heat buildup or loose connections, so it’s doing what it’s supposed to.But if you're looking to go from a TT-30 to L14-30R setup, this works.For the price, it’s a good buy. You can spend more on a fancier one, but this does the same thing. Would grab another if I needed a backup.

This adapter cord allowed me to use my long extension cord with the L14-30 plugs to run power to my camper, very pleased and would recommend.
