One Response to “Electrical Wiring for a Dishwasher and Disposal Outlet”
  1. James H. Stradling says:

    My only comment would be to check the receptacle itself if normal troubleshooting doesn’t reveal the problem. Sometimes the tabs are broken on a duplex receptacle so that they will act as two separate “outlets”. This is done if one outlet might be switched (as in the garbage disposal) and the other might be switched or will remain “live” all the time (as in the dishwasher).
