So - have a wiring question about going from a 4 wire (3+G) cable to a 3 wire (2 +G) cable.

As is there is a designated circuit which comes from the breaker (double pole) with 3+G (Old cable, red, white, black and G) to an outlet.

The cable OUT of the outlet other side goes to a dishwasher - and is a 2+G cable.

In the box, the red (from 3G) and the black (from 2G) are connected with a wire nut. The black and white from the 3g and the white from the 2g are connected to the outlet.

I was going to replace the outlet with a 20A GFCI - but hadn't realised until I got in there that there was a 3+G cable which the wiring instructions say not to use.

Can I wire in the GFCI the same way as the previous outlet?

Thanks!

I think you are saying that there are two hots and a neutral, and a box. So do you just isolate the extra hot, or use a 4-inch box with two GFCI outlets... and each gets a hot and a neutral.

I think codes want you to either use a 2-pole breaker to power the two hots, or to have the two single pole breaker handles tied together in a prescribed way.

See attached images - one showing existing, and one showing what I think I can do - splices shown as blobs.

Look right to you?

Yes. This presumes you have 240 volts between the red supply and the black supply.
