How To Install a Quad Receptacle or Double Duplex Receptacles

June 24, 2008

In today’s article, we are going to discuss how to install a quad receptacle or double duplex receptacles. In this article, I will provide step-by-step instructions with pictures for this installation. Please click on the images to enlarge them. Each picture will open in a new window.
Step 1. Measure for the desired height of the receptacle box. We typically install these at 12 to 18 inches above the floor to the top of the box. I recommend matching the existing height of the other receptacles in your home. Measure height for receptacle box
Step 2. Install the 2-gang receptacle box. Install the 2 gang receptacle box
Step 3. Install the NM cable (romex). A 15 amp circuit requires 14/2 with ground and a 20 amp circuit requires 12/2 with ground. Install the romex
Step 4. Strip the cable and ensure there is at least 1/2″ of the sheathing sticking into the box. Ensure there is at least one half of an inch of the sheathing in the box
Step 5. Staple the romex to the center of the stud. Your first staple should be within 12 inches of the receptacle box and every 4 1/2 feet thereafter. Staple romex within 12 inches of the box
Step 6. You need 6 to 8 inches of wire, measured from the back of the box. 6 to 8 inches of wire measured from the back of the box
Step 7. Strip the wires and install 2 – approximate 6 inch long pigtails on each wire. Strip the wires and install 2 - 6 inch pigtails
Step 8. Install wirenuts on the end of each connection. Install wirenuts
Step 9. Fold the wires into the back of the box. Fold the wires into the back of the box
Step 10. Strip the wire ends and bend a half circle on the wire ends. Connect the ground then neutral wires to the receptacle. Repeat this for the other receptacle. Connect the ground then neutral wires to the receptacle
Step 11. Connect the hot wire to the receptacle. Repeat this for the other receptacle. Connect the hot wire to the receptacle
Step 12. Install the receptacles. Install the receptacles
Step 13. Install the double duplex cover plate. Install the double duplex receptacle cover

    I’m looking for (in a new construction home) some method of finding an electrical light receiptcal box that the sheet rock crew covered up. I just know it’s on this particular wall. I’m open to any suggestions

    I want to hang a 16″ tv over my double door closet in my bedroom. Can I just put a outlet box into the 2×8 header or do I have to hide the box in the closet and just run a line through the header for power?

    Large or doubled-up pieces of wood are there for a reason, don’t go cutting them. A header is usually there to distribute load. Generally you can’t just cut through one, at least not for a hole large enough for an outlet box. But if there’s a wall cavity then you could probably use that. Or put it on the ceiling. Speak with a local licensed electrician or the county permits bureau.

    I was wondering if the quad outlets could overload a circuit and if it would be better to run romex from two different circuits, one to each outlet.

    I have three bedrooms and family room on one breaker is there any way to split them up. All rooms are finished.

    I wish there was more pictures for steps 10 & 11. I’m really curious to see how you connected the two oultets together, there are a couple ways of doing it. I’m just curious what is the best.
