Control Panel Power Connection advice needed. IEC?

I have two extension cords going to the control panel. A 20amp 120v for a 2000w element and a 15amp 120v for the pump.
I would like to connect the two cords into a jack on the control panel. On the other side of the jack I would there to be posts for quick disconnects.

What's the best way to go about this?

IEC Power Inlet like this?
Then attach an iec adapter to the extension cord to plug into the iec power inlet? I can't find this adapter...

Or,

Is there a power inlet somewhere w/ quick disconnects that I can just plug the extension cords into and quick disconnects to the inside of the control panel?

Yes!
It says 250v, should work fine for 120v though, right?

Thank you!

250v is its maximum. it will work on everything under 250v.
