Neat idea. Good directions. I've seen questions like this several times and never thought of using a 3 way like that.A simple procedure, actually. Just install a "3-way" switch. Wire it so that when the switch is down, power goes to the dishwasher. When the switch is up, power goes to the disposal. Non-coincident loads that way. You can break off the tab on the receptacle outlet to make each half of the duplex dedicated for each appliance.
- Turn off power to your outlet under the sink.
- Install a piece of 3-conductor cable from your existing outlet to your 3-way switch.
- Disconnect the black wire from your outlet, and wire-nut it to the white wire of your switch leg.
- Connect the other end of that white wire to the "common" terminal of your 3-way switch.
- Connect the black and red wires to the other 2 terminals of your 3-way switch.
- Break off the tab on your duplex outlet on the "hot" side of the outlet.
- Connect the remaining black and red wires from your switch leg to the 2 terminals on your outlet.
- Mount all devices, install wall plates, etc.
- Turn on power, and check which position of the wall switch controls which half of the outlet.
- Plug in the disposal unit to the portion of the outlet that is on when the switch is "up"
- Plug in the dishwasher to the portion of the outlet that is on when the switch is "down"
Why bother? :huh: Because it is a much simpler procedure to install a switch setup like this, than to install a new dedicated circuit back to the panel.OK, but why bother? A 20A circuit can easily handle the sort term load of both.
No more or less than a standard single pole switch is rated for a motor load. And that is what is commonly used for a disposal setup. :yes:Is a standard 3-way switch rated for a motor load?
Got all the stuff, wasn't sure putting it outside the wall is going to meet code? So, I took pics and have more questions.I want to add a switch for my g/disposal under my sink. There is an existing outlet for the DW under there. How do I add a switch from this outlet? I need simple instructions or a tutorial. I am not an electrician.
Under the cabinet. I already have the counter top and new backsplash on and I thought under the cabinet would be o.k. We bought a blue box that can hang sideways from the front lip of the cabinet. But I can get another kind if you instruct me to since I am taking back the 3 way.Wow, this may be better than originally anticipated. You see that extra red wire in that box? That is most likely a spare circuit conductor meant for your disposal.
You won't need the 3-way switch after all.
Now, exactly where did you want to install this switch? Under the sink? Above the counter flush mounted into the wall?
Instructions can be different for each scenario.
So I guess all those shows about flipping houses in California are not just cliches and stereotypes. :whistling2:o.k. this is a project house, purpose is to sell high with a minimal budget. I am rehabing a friends old house to make a better profit than an "as is" price. ......... and would rather not pay expense for the air switch. ..... Please help me with the steps to do this that will meet code in the least expensive way. Thanks.
Uh....helloooo. It may already be pre wired for a disposal switch.Please help me with the steps to do this that will meet code in the least expensive way.
