Duplex switched outlet conversion . .


Under my sink I have a duplex outlet. The garbage disposal is plugged into one of the receptacles and is controlled by a switch. I am going to be installing a dishwasher where there never was one before and want to plug into the other receptacle on that outlet, problem is, both receptacles are controlled by the switch. I am not sure what I need to do to make one of the receptacles switched and the other always hot. Do I just not break the tab on one side of the new outlet ?

Thanks

Depends on how it is wired.
Does the power feed into the switch or the receptacle first?

If it feeds into the switch first, you may need another wire to the receptacle.

So if I pull the switch and there are 2 pieces of romex coming into the box I have power to the switch and I gotta figure out how to get new wire to the outlet ?

So, power does come into the switch box first. . . .
What is the best way to try and feed another wire down to the receptacle box ? I am guessing none of the options will be 'easy'.

It would probably be easiest to run a circuit from the panel and drill up into the sink cabinet and install a new receptacle. This way, you won't have to worry about the disposal being on a lighting circuit then adding the dishwasher to overload the circuit or the problem of dimming lights.

Okay, I was thinking about that as well. My only problem is, this is on an outside wall, and because of how the joists run, and sit on the foundation it will be very difficult to drill up through the sole plate so I can put the outlet in the wall.

Would it be acceptable to put a surface mounted metal junction box inside the cabinet, and just drill down through the cabinet and subfloor (similar to how the water pipes come up), and then create a new circuit. I would use conduit coming into the junction box in the cabinet, and down through the floor to the basement.

Put the receptacle tight to the bottom of the cabinet and run romex right into the bottom of the box. No need for conduit then.

Could I just hard wire the dishwasher, or put the outlet box on the floor in the dishwasher cavity, or is that not advisable ?

Check the instructions which came with the dishwasher. Most can be hard wired. You can mount a box to the floor in the dishwasher space. Or to the cabinet side wall if there is room.
