Welcome. My name is XXXXX XXXXX would be glad to assist.To better assist, a item to determine what the problem may be.Do you have a 2 lead voltage tester?Is there 2- duplex receptacles (4 plug ins) or just 1- duplex 2 plug ins)?
Is the breaker for these a 2 pole or single pole breaker?
Yes, I have a multimeter and can do various tests.
Here is only 1 duplex receptacle (with 2 plugins: one for dishwasher and one for garbage disposal).
The breaker is 2 poles (and the handles are tied together).
One thing I noticed is that the wires on the breaker: one is red and one is black. Should it be all reds for both poles?
I checked the breaker. Both wires (red and black) have power (120v). However, in the switch box, only the red wire has power. The black does not have power. What does this tell us? The connect from the panel to the switch box has issue (that is, the black wire has a broken connection some where from the panel to the switch box)? If so, how to fix this?
Yes, all my previous tests are against the ground. Yes, only red has 120 volts at the switch box. Yes, the breaker has 240 volts between the two poles.
The panel is in the garage, which is only about 20 feet away from the sink (direct line distance). The cable is inside the wall.. how do I trace the cable?
Is there any tool to help trace the cable without open up the dry wall?
I found the following from the internet:
"The device I am thinking of attaches to the wires at the breaker panel and emits a high freq signal. Trace the signal with a portable reciever and when you lose signal, backtrack about a foot and you'll fine the end of the wire. MAKE SURE you turn off the main breaker before attempting this."
Do you such device? What is its name? Thanks.
Thanks for the suggestions. I got an electrician in. He said the wire may go along the cabinet wall (along the kitchen) and it is hard to lay a new line (since there is no attic due to second floor). So he suggest to use the red line to power both the dishwasher and the disposal.
Do you think this is a safe, and building-code compliant?
