Electrical Wiring in the Home/Garbage disposa electrical


We have replaced our garbage disposal.We also changed the switches.  The house was built in 1990.  The previous switch did not have a ground on it and the current one does. There were ground wires bundled in the receptacle but were not being used.  We are now using 2 of the 3 (one for the dishwasher and one for the garbage disposal).  Since the dishwasher works and the disposal does not, should we be using the 3rd?  It doesn't make sense to me, but then much of what the builders of this house has done, does not make sense to me.

The ground is suppose to be one continues price of metal connected to all the metal devices in your electrical system. Your old switch may not of had a ground connection it the switch was plastic framed (yoked). Your 3 grounds need to be twisted together first. Then it doesn't matter witch one connects to the dishwasher or disposal.

The grounds will not keep any of your appliance from working. They are there only to keep the metal case of your appliance from becoming energized. It is for safety. I'm sorry to say, but if the disposal is not working you may want to call in an electrician to check the wires.
