Wiring in new dishwasher

hellothere123 · 09-12-2010, 09:11 PM

I am wondering for the new power to the dishwasher can I tap off any outlet nearby?

And if I want to increase the size of the breaker (beacause the close outlet has a kettle and microwave on it, it will trip if I add the dishwasher) how do I know what size to incease it to? How do I know what would be safe emough for the outlet but also not trip when the dishwasher is on...

Thanks!

The breaker you can use is determined by the wire size
#14g wire = 15a breaker
#12 wire = 15a or 20a breaker

Dishwashers typically have individual (dedicated) 20 amp circuits. Kitchens in the USA have very strict requirements for the branch circuits to receptacles. I suspect Canada to be similar. One of our members 'Joed' is a Canadian electrician. If you monitor this post a few days he should respond.

Thankyou for both of your posts.

I have heard both ideas, one that you can just tie it in, and other that you have to have a dedicated line.

I'm thinking it might be a better idea to run a dedicated line, since that circuit is already tripping the breaker with what is on it.

Back to the existing plug that runs the microwave, kettle,toater, etc since it trips the breaker would you put in a bigger breaker or run another line to the outlet (since it looks like I'll be running a line already for the dishwasher)

I was reading online that kitchen outlets should be wired with 12 guage (since they need 20 amp breakers for dishwasher and microvave) and that the dishwasher should also be wired with 12 guage wiring. I cheked all of my wiring and I only have 14 guage throughout the entire house...

Maybe they mena that a regular plug in microwave can run on 14 guage and if you install an over the range microwave then you need the 12 guage???

Some very erroneous answers on that link.....

One of the answers was ok.

Joed should be along if I bump this to the top of the list.

No you can't pull the power from the counter plugs for your dishwasher. The counter plugs are for the counters only. Check the amperage on the dishwasher, they usually have a higher amp draw so I would recommend to run a sperate circuit for the dishwasher.

have no idea if its legal or not, but either way its a bad idea. Run a dedicated 12/2 for a 20a circuit

You can get away with 14/2 and a 15A circuit, it will save you a little bit on the wire.

I just read that thread on yahoo and all I can say is wow. How can someone say to run #10 on a 30A breaker and then say to drop it down to #12. Everybody was saying no to that answer but you could very easly use 14/3 and run both.

Be very hesitant to follow any advice on yahoo answers. I used to answer questions on there but there is so many crappy and dangerous answers on there that get selected as best answer I had to stop. There were a few occasions I would give a correct answer and then someone came along and gave an obvious incorrect answer and I would get 3 or 4 thumbs down.

Once again thanks...I'll run new lines and have a friend of mine who is an electrician terminate them in the panel since I have never opened up one before.

Wow...I just read that Yahoo thread
