I have a single GFCI receptacle under my kitchen sink, and I want to power one end with constant power for the dishwasher and the other end with the switch leg from a switch on the backsplash for the disposal. Can this be done? I don't see the normal tab you can break on regular receptacles to do that on the GFCI.

    You want to make half of a GFCI receptacle switched. Is that correct? Commented Aug 23, 2017 at 23:14
  • What is this GFCI fed from? A kitchen SABC, a lighting circuit, or a dedicated branch circuit? Commented Aug 23, 2017 at 23:15

    Also, are you a person who believes firmly that a GFCI is a type of receptacle? Or do you believe a GFCI is a protection device that comes in many forms, and one of them has a couple convenience outlets, and all of them can protect downline loads? I'm not here to challenge anyone's beliefs but if you believe the latter, options open up. Commented Aug 23, 2017 at 23:17
  • I'm going to assume what this is: You have a switch, it powers a GFCI, the GFCI has a garbage disposal power feed in it (either plugged in, or wired in) and you have two outlets? Just an FYI and I may be wrong, I believe if a dishwasher is permanently mounted, it is supposed to be hard wired. I also believe it is supposed to be on it's own circuit. hopefully someone up to speed on code will comment. But if your goal is to have both appliances GFCI'd, I would add romex to the switch box/outlet, and drive the GFCI unswitched, route the disposal to the switch.

  • Dishwashers do not need to be hardwired. Actually, if you have had a dishwasher installed recently (by a Loews or HD installer), they will refuse to install a dishwasher if the current one is hardwired. They are not ‘electricians certified’ so can only ‘plug/unplug’ the electrical, hence this rule for them. Converting to a plug is generally an easy DIY for many home handyman types. Look it up on YouTube. Costs about $20 and takes about an hour!

You cannot split a GFCI receptacle, however, a GFCI receptacle is not the only way to provide GFCI protection to a circuit.

GFCI Circuit Breaker

One option, would be to provide GFCI protection to the entire circuit by installing a GFCI circuit breaker. Install a 20 ampere GFCI circuit breaker, and run 12 AWG copper conductors to the receptacle location. Then you'll simply wire a standard receptacle, in a half switched configuration.

Blank Face GFCI Device

Another option, is to use a blank face (dead front) GFCI device to provide protection.

  • Install a double wide box at the receptacle location.
  • Connect the wires feeding into the box to the LINE terminals on the GFCI device.
  • Use the LOAD terminals on the device to feed a standard receptacle, wired in a half switched configuration.
