Question Adding Electrical To Kitchen & Bathroom Myself!

I hired a friend to add a kitchen & bathroom to a garage to make a studio.
He left everything half ass. I have completed everything myself, drywall on ceiling, putting kitchen & bathrooms in, toilet, jacuzzi, plumbing, floors, carpet, studs, etc.
Now I am at the electrical. I have 2 spots for circuit breakers. I want to run about 8 outlets total on 14 gauge wire on a 15 amp circuit is this correct?
Then I want to run for my fridge, garbage disposal, jacuzzi & dishwasher on the other circuit breaker spot. This is on a 12 gauge wire on a 20 amp circuit breaker is this correct?

Any help or advice would be great appreciated.

If you're adding a kitchen you'll at least need two 20 amp circuits for the receptacles, and you'll probably want to break those appliances into 2 or more circuits. Any bathroom receptacles need to be on their own 20 amp circuit (if it's a single bath you can use this circuit for the light and bath fan too).

Sounds like a subpanel will be your best bet.

No, it's not correct! You need more than two circuits, so you may need a sub-panel.

I am afraid you need to do a bit a read and searching of this forum. Codes for kitchens and bathrooms are rather involved. And you must get it right.

Many circuits for the kitchen must be dedicated. For example, the fridge, dishwasher and microwave must have separate circuits. The countertops must be 20 amp CFI protected (at least in the US). Each circuit can only serve two outlets, and no other outlets are allowed, not even lights. You must have at least two such circuits. Etc, etc. There are many more requirements. This is only a brief outline of the code.

The bathroom must also be served by a dedicated CFI circuit. If the circuit is used in only one bathroom, you are allowed to connect the bathroom lights.

I am not trying to put you off, with a little care itís certainty possible to do the work yourself.

Before continuing you must do some reading, or you are headed for problems.

Kitchens and bathrooms are the most electrically regulated rooms in your house, and rightly so. If you guess, you will surely get it wrong. There are probably a hundred codes you need to know. I recommend the $6 green paperback, Wiring Simplified, often sold in the electrical aisle at Home Depot. It will cover what you need to know. Read it thoroughly before doing anything.

Unless modified by local Codes I must correct a few items from Impeyrs post

Refrigerators normally do not require a dedicated circuit unless the manufacturers directions call for one. They can be on the small appliance countertop circuits.

Quote "Each circuit can only serve two outlets". The Code does not state a limit on the number of receptacles on the small appliance circuits. It does however have limits on the rooms in which the small appliance circuits can power receptacles.

Your jacuzzi will also need a dedicated GFI protected circuit.

I stand corrected.

Having said that, my statements ARE correct for the new Canadian codes.

Also, why would you risk the contents of your fridge by not using a dedicated circuit? Makes sense to me. As for the countertops outlets, again, since some appliances can have large draws, limiting the number of outlets per circuit is a good idea.

You are allowed to go beyond the letter of the code.

I have ten counter top receptacles in my kitchen. They are arranged on two 20 amp circuits, five receptacles per circuit. The refrigerator has a dedicated 20 amp circuit, as does the over-the-range microwave. The disposal and dishwasher share a 20 amp circuit.

I have never overloaded the counter top circuits. Are you seriously suggesting that you would recommend five separate counter top circuits? That would be overkill.

You have to look at the complete picture. There are a lot of differences between Canadian and U.S. kitchen codes, and we've only mentioned one part of it in this thread.
