Receptacle with two breakers...

Here we go...

We are installing new cabinets in our '79 kitchen.
Under the sink there is a recptacle.

The top was for the garbage disposal and has a switch above the sink for turning on and off. (It is on a breaker with several other plugs.)

The bottom outlet was for the dishwasher.

We moved the receptacle without diisconnecting any wires. (less than 12 inches) We then decided to change out the recptacle from the older colore to white.
At home depot, the gentleman said that a regular recpetacle was fine for this. So, we wired the new receptacle after removing the older one.

Problem, The top one works, and the bottom one works, but when we tried them at the same time, the breaker flipped to the bottom, we tried again and when we turned the switch on for the top outlet, the switch spit fire and blew. ( when we were tesing these outlets, we weren't using the appliances, rather small fans) What is the problem?

We get this question at least once a week. I hope you still have the old receptacle for comparison. Look carefully at the brass screw side. Then compare it closely with the new receptacle. You'll notice that the old receptacle has the tab removed from between these two screws, and the new one does not. Take pliers and bend this tab back and forth a few times until it breaks off.

Note that this is a multiwire circuit. Such circuits can be extremely dangerous if messed with by someone not familiar with such circuits. So before you change anything at all, study up on the peculiarities and special hazards of such circuits.
