20A Tandem Breaker - dishwasher and microwave
I am planning on installing a dish washer in our kitchen. There was never one there before, so I will have to run all new electric. I know most manufactures recommend putting a dishwasher on it’s own circuit, however last fall I installed a microwave on it’s own 20A circuit which took up the last available space in my box. I was discussing with an electrician friend of mine and he suggested getting a 20A tandem breaker, replace the 20A microwave breaker with this, and then put both the microwave and the dishwasher on the tandem. Looking at the layout and specs that were included in my electric box, it appears I can use a tandem breaker in any slot. The microwave and the dishwasher would be the only items on the tandem circuit. From what I have been able to research, this seems like this would be up to code. I wanted to see if I could get some opinions on this and see if this approach really is in fact code. Any input is appreciated, thanks!
