Daughter bought new house (for them) build in 2005.

From the panel, a 20A 2-pole CB feeds into 2 separate single pole switches in a 2-gang box, from there feeding a split receptacle under the island sink base cabinet. One switch for DW and the other for GD.

I want to use the right-side switch for the light over the breakfast nook because I am removing the partition wall that the only switch for that light is on (strange that the light is not on a 3-way switch setup).

The dishwasher has a cord and I don't think it was ever hard-wired given it's the original DW - perhaps just the old kid-proof approach.

So I will remove the red and black from that switch and tie them together so that half of split receptacle is always hot and that will be for the DW. The GD wiring stays as is (switched).

Then I can use the now free switch for breakfast light which is on a separate 15A circuit. I'm not a big fan of having 15A and 20A circuits in same box but in this case no easy way around it. I will tie all grounds together but keep the neutrals separate.

Good to go as described ?

Thanks very much.

If you bring the 15 amps on the three wire, it won't have a neutral to worry about.

Thank you but I am not double switching the light (3-way), just going to run the current power and switch leg into that 2-gang box and use that switch that I robbed from the DW being switched.

Hope I am being clear here - sorry if not.

Now I understand and I don't know the rule on that. Problem would be to work on this switch, you would want to know there are the double and a single breaker to turn off.

YES. Good as described.
You may not be a fan but there is no issue with having 15 and 20 amp circuits in the same box.

To the same double switch in a single box?

I know of no code restricting a junction box to one circuit or one amperage. You could have 15 amp circuits in the same box with 40 amp circuits if you want.
As long as you keep the circuits separate, except for the grounds, all is well. All grounds in the same box always get tied together.

You do have to remove the tab between the screws on the hot side of the switch.

Yes for the double switch on one yoke. I thought we were talking about two separate switches in a double box.

??? Tab on switch??

Yes on a double switch on one yoke there is a tab so you can have two completely independent switches.

Two screws have a tab between them so you can feed them both with one wire, you just break that out.

My setup is NOT a double switch, it is 2 separate single pole switches in a 2-gang box.

But yes, if it were a double switch, you would break off the tab, turning the double switch into 2 separate switches.

Hopefully anybody working on it would check for voltage in the entire box before working on either switch right - if not, they would certainly know if they touched that hot wire on the other switch - yikes !

:biggrin2:Okay, I only misunderstood few detail.
