Gfi

Hi,
I am going to have a new line run from my fuse box (20amp) to under my kitchen sink. This will power my dishwasher and garbage disposal. Can I put in a GFI receptacle then make my dishwasher line a plug in and run a plug ended wire to a switch to operate my garbage disposal.
Thanks

Yes, you can do this.

Two points: (1) it is neither normal nor required to run a dishwasher or a garbage disposal on a GFCI. (2) although your plan is fine, a deluxe job would be to run two separate circuits, a 20-amp for the dishwasher and a 15-amp for the disposal.

Although regular duplex receptacles can easily be made half-switched (i.e., switch only the half that the disposal plugs into), you cannot do the same with a GFCI receptacle. So if you use a GFCI receptacle, you'll also need a regular receptacle.

I'm not sure what you meant by, "run a plug ended wire to a switch," but it sounds scary.

Thanks John........

Did'nt mean to scare you...my typing wasn't quite as fast as my thinking. What I meant to say was; I would like to run a plug ended wire to the new GFI receptacle with the other end terminating at the switch to operate the disposal.

Your feed back was great. It looks as though I don't even need a GFI receptacle at all and can use just a standard one. I wasn't sure if for safety reasons, being in the kitchen and all, that GFI was required.

My big concern was making the dishwasher plug in rather than hard wire. I wasn't sure if it would be a problem.

Yes, put a 4x4 box in and put a switch in one side to half switch the recept as John said.

Forgot to mention the provisions of article 422.16(B)(2).

Code severely limits the length of the cord for a cord-and-plug connected dishwasher. The only way to do this is to put the dishwasher receptacle immediately behind the dishwasher (in the dishwasher cavity -- not under the sink). The cord can be no longer than what is necessary to allow you to pull the dishwasher out no more than 48" (from the back of the dishwasher to the wall behind the dishwasher).
