I wish to run two 20/2ga dedicated lines (dishwasher and garbage disposal) from my breaker box (two 20 amp circuit breakers) to one plug outlet? Do I merely "open" the top and bottom side connections on each side the outlet? Then connect the disposal to the bottom "plug" and the dishwasher to the top "plug'? And what rating outlet should I use?

You're on the right track. You'll need to handle tie the breakers. You'll need a 20 amp receptacle.

Will you be running one 3 conductor or two 2 conductor wires?

How are you going to control the disposal?

 

[Jim Port]

Under the 2014 NEC the DW receptacle needs gfi protection .

I have total access to the wall (and attic to breaker box) so I was planing on running 2) 2 wire lines. I was hoping to place a switch in the same box as the new outlet. Handle tying the breakers is no prob, didn't know about that!

 

[Ramblin Jack]

Wait I brain farted, the switch will not go into the outlet box, sorry. There will be at two separate locations. The outlet under the sink ND the switch above the sink.

Jim Port: I can put in a GFCI but then I can't "separate" the lines for both DW and disposal on the same outlet. Right? Or is this where the 1) 3 wire line comes to play?

 

[Jim Port]

A gfi receptacle cannot be split wired across two circuits or be half switched.

Install a 2 gang box with separate receptacles. No handle ties required with separate cables. And you can use 15 amp receptacles with this configuration.

 

[Ramblin Jack]

That's it then. Two-gang box it is and thank you all for your valuable expertise. I'm brand new here and glad I stopped by!!!

I would use 12/3 instead of two 12/2 if it was me.

Not required? Shutting down one circuit would still leave power in the box.

Not a code issue to have 2 circuits in the same box.

 

[circuitman]

might not be a code issue, but my opinion it's still a safety issue unless it is noted some way. just my 2cents!:surprise::surprise::surprise:

 

[Ramblin Jack]

That is a good safety point IMHO. There is no risk (downside) utilizing a handle tie then, correct?

 

[rjniles]

Handle tie required for MWBC and 2 circuits on same yoke. Not required when 2 circuits in same box. But not a problem if you want to do it.

Thanks for that. I am in the process of 'correcting' all the back-stabbed connections as I repaint rooms and moments ago found two boxes with two circuits. Shows the need to prove circuits safe before poking around in them.

That is true even if there is only 1 circuit.
