Hello,

I'm trying to shop around for a possible extension cord for this 250v, 50amp outlet.

We'd be trying to use an electric dryer from this, but would preferably have it extend nearer a window on the other side of a garage (~25-30 ft, generous measurement). We'd likely pick up an older, used, basic dryer model, and not sure what those electrical needs will specifically be, but trying to plan ahead in case something needs to be altered.

This is the closest I've found which might work:

https://www.homedepot.com/p/VEVOR-Extension-Cord-25-ft-10-Wire-Gauge-Heavy-Duty-Outdoor-Welder-Extension-Cord-with-3-Prong-30-Amp-Power-Extension-HJLJQ10-3-25FTYCXV1/320761106

Most other cords with 3 prongs had them sort of curved/circular. Yet, this says only 30 amps.

Is there different or specific wording which might assist my search? Or would something like the above cord work for our situation?

Thank you for taking the time to read my post. I appreciate any advice or directions.

No expert, but I think the 50A is just the max based on the rating of that receptacle. If a dryer only pulls 20A, then a 30A extension cord should be enough, right?

I'm not much help here. Just my 2 cents that might expand your available options. Additionally, someone suggesting the wrong thing makes experts more likely to correct them and give the poster the answer they are looking for.

He can swap that breaker and receptacle for a 30A and be fine if he only needs 2 hots or 1hot 1neutral.

I can confirm, the dryer will have the amperage it uses on a sticker on the back or it can also be found on the manufacturer's website and as long as it's less than what the cable and outlet are rated for your good.

He needs to swap the breaker to a 30a

I'm really glad you mentioned that. Just recently bought a dryer. I'll have to check the breaker rating.
