Red wire is connected to ground screw in my 110 volt receptacle
That outlet was miswired, and I would be very cautious with all of the wiring in that house. There's no telling what other &quot;shortcuts&quot; were taken.

Provide photo(s) of the outlet/setup.

Does that Romex also include a bare wire?

Does a circuit tester (like below) show the outlet as wired correctly?
   

Get yourself a voltage tester.

Also get yourself a continuity tester. If possible, rent or buy a MegOhm
Meter, AKA &quot;Megger&quot;.

Switch off and or unplug everything on that circuit.

Switch the breaker off or unplug the fuse at the circuit panel.

With a voltage tester, make sure that no AC is present in the outlet.

The megger should show very high resistance (greater than 200K ohms) between the hot (black) and neutral (white).  If it doesn't, something is still on that circuit or you have a serious problem.

The megger should show less than 2 ohms resistance between the neutral (white) and the bare wire (if present).

In this case, the megger should also show less than 2 ohms between the neutral and the red wire.

Trace the red wire through the house/junction boxes and make sure that it eventually connects to a proper ground wire or the ground buss in the main panel.

If the bare wire is present and grounded, use it instead of the red wire.

If not, and the red wire is properly connected to a ground, then wrap the ends of the wire with green electrical tape at every box/or panel where it appears.  This is the code correct (in many jurisdictions) way of indicating the non-standard wire use.

If the above conditions are not met, or you can't trace the wire, hire an electrician.
