Wiring – 3-prong grounded female plug for 12-gauge wire with an 18-gauge ground wire

wiring

I am trying to find a 125V female plug receptacle with ground for a 12-gauge wire run in the 1960s, the ground wire of which is a much narrower gauge than the white and black conductors. The Levitons and the P&S's at the big box stores assume the three wires are going to be the same gauge, and so they don't get a tight grip the ground wire; it just slips right out. Is there a name for such a connectorenter image description here?

Go ahead and buy the modern version. To make the light gauge ground wire secure, add another bit or two of wire—each an inch or so long—beside it into the terminal.

This will fill up the slot enough so that the screw meets the wires and can clamp them together firmly.
