I am trying to wire a 12/2 romax to a wall outlet under the sink to service the dishwasher and garbage disposal all on one outlet, but top outlet of the two I would like to have controlled by a switch above the counter. The bottom part on the other hand, I would like to have hot at all times for the dishwasher. Both off course protected by a circuit breaker in the basement below.
Is there a way to break the connection between the top and bottom outlets within the unit?
If not, what is the common practice to accomplish this, so that the dishwasher and garbage disposal live on the same outlet?
