Part 1. Wiring a Combo Switched Outlet or Half Hot Outlet
Applications for Combo Switch Outlets
- Scott, a combo switch outlet will require the set of wires that are for the switched device, in this case the disposal, and the outlet will require a hot, neutral and ground wire.
- If the combo switch outlet is being installed at the kitchen counter top area then the combo switch outlet will need to be a GFI combo switch outlet.
Part 2. Switch and Outlet Wiring
How to Convert a Switched Outlet
- The switch I am replacing has two red wires plugged into the back of the receptacle, and two black wires plugged into the one below.
- If I want to keep the same set up I can just connect the two red to the top brass screw and the two black to the bottom but must break the small brass tab between the screws not the plastic, correct?
- If I don’t care to use the wall switch all I have to do is to cap off the red and connect one black to one brass screw and one to the other brass screw w/o touching the brass tab,correct?
Wiring Modification for a Non Switched Outlet
- Insulating the Unused Wire
- Yes, the red wire may be capped off and the outlet may remain hot all the time.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
