Quad outlet wiring

[OKDart]

I'm wanting to move a quad outlet and reduce it down to a duplex. This is in a circuit with several quads, each have a GFCI. I would have thought that they would only have 1 hot, 1 neutral, and ground. What do you make of the pic? Why the extra wires? The black wire read 124 VAC, no voltage reading on the red. How do I condense this down to a duplex?

The red and white is feeding more outlets that you don’t seem to be aware of. You won’t measure any voltage on the red until it is inserted into the gfci which feeds downstream. It’s not live.

(I am viewing on a small screen that's what I figure from the 1st picture, I could be wrong)

If you notice the GFI outlet has a line (top)
and load (bottom). The black and white on the line
are the incoming supply (non GFI protected), the
red and white on the load are the out-going
GFI protected wires. Disconnect the out-going
red and white from the GFI. Connect the red and
white from the duplex that go up the pipe to the
load side of the GFI.
I hope this makes sense?
Let me know if not.

OK thanks, I feel stupid now. This outlet is a leg 10 ft below the main run. I couldn't comprehend why it would need to be run in series, but I guess with GFCI it has to be.

BTW, there are multiple GFCI outlets in each circuit, isn't it only necessary to have one per circuit?

The guy who wired it maybe didn't want to lose all of them if the GFCI tripped. So each GFCI feeds two other receptacles, that sort of thing.

Snarky comment, but I cannot imagine ANY scenario where I'd need to reduce a surface mounted quad in an exposed EMT system to a duplex.....

Agreed! Most of our shop wiring was done with quads. Only certain dedicated receptacles were done as singles. Actually about to replace one of the singles with a quad.

Also, could be multiple circuits also. Hence multiple GFCI's.

It is common to alternate 1, 2, 3 circuits in a receptacle run like a kitchen counter or surface mounted runs. This way if 2 devices are plugged into receptacles next to each other they are not pulling from one breaker.

I wired our kitchen and the shop alternating circuits every other drop.

Example: Each letter is a circuit (breaker).

A, B, A, B, A, B

or

A, B, C, A, B, C

I've framed in a room in my shop and it'll be drywall. The room (1000 sq ft 2 story) now has it's own subpanel. The existing quad off the main panel at 3 ft high is not needed anymore (EMT is coming from above, can't get any lower), so I was planning on flipping it around to make an exterior outlet. A duplex is plenty on the exterior wall. I don't even know if they make a quad exterior outlet.

Got it.

I like surface mounted boxes for exteriors- keeps the penetrations to the size of a conduit ******. Dont like flush boxes, screwing with plates, water leaks, etc.


nsula- exactly how I did my shop. Each quad outlet has two circuits, one for each duplex device.

There are two gang exterior boxes and box covers. I have one on my garage, I have used all four outlets, or at least three of them, at the same time with some frequency. The one I have came with inserts to have an assortment of different of devices or combinations.
