Has anyone here heard of a digital potentiometer for household current?

[LURCH]

Has anyone here ever heard of a digital potentiometer that is built for household current? I'm talking about US power supply (110v 60Hz AC). I've been looking for one to buy. I tried searching online to look for prices, only to find that they don't seem to exist.

Any links to an online store, or information about the existence or non-exitance of such a device would be greatly appreciated.

Looking at electronics supply houses, it seems that digital potentiometers are sized to control IC circuits, and can't handle more than a small amount of current. I could be wrong, but take a look at the supply currents in this table.

Not sure what you mean by a digital potentiometer for the AC Mains. I've not seen a use for a potentiometer on the AC Mains. Are you thinking more of a variac, to get stepped-down versions of the AC Mains voltage? Or are you looking to dim something like a light? If dimming, you don't use a potentiometer. You use triacs or SCRs to make dimmers:
