I've been getting a little confused reading through NEC 210.52, dwelling unit receptacle outlets, specifically on the kitchen.
Attached below is a diagram of my main floor circuits. The lighting circuits aren't included on the diagram, those are all separate now (two circuits, alternating pattern in case one trips.)
My panel is full (20 breaker box), but I know I need to make some more room. Luckily one is for the pool which was taken out before we got the house. I can make some other room by combining a few dedicated circuit outlets in the basement that don't need to be dedicated with what we do down there.
Just want to make sure I get this right.
So, there are six circuits in my kitchen:
#2 - 15A, 14 AWG - OMG what idiots. Microwave is on the same circuit as the family room AND garage. Microwave is marked to run 14-15A, LOL. Even though it's a 15A circuit, microwave is plugged into the only 20A outlet in the house. (Microwave does use a 15A plug.)
#4 - 20A, 12 AWG - Two 15A duplex outlets. We never use these. One is underneath the windows, and the other is behind a desk + hutch.
#6 - 20A, 12 AWG - Two 15A duplex outlets. One outlet runs the igniter on the gas stove, and the other runs the fridge (marked to run 4.5A)
#11 - 15A, 14 AWG - OMG what idiots. Garbage disposal is on the same cirucit as two and a half bedrooms, including my computer. Explains why my two monitors just died. Disposal is marked to run at 8.1A.
#13 - 15A, 14 AWG - One 15A duplex outlet. We have a small nightlight and a toaster oven plugged in.
#17 - 20A, 12 AWG - Dedicated outlet for dishwasher.
I know I need to run a dedicated 20A circuit using 12 AWG to the microwave.
I know I need to get the garbage disposal onto its own circuit
So, my questions:
Question 1 - Since the oven is gas, and only needs electricity for igniting the gas, is it OK that it's on the same circuit as the fridge? It's a 20A circuit, fridge is marked for only 4.5A.
Question 2 - Code requires at least 2 20A small appliance circuits. I'm getting confused about that term. Anyways, are circuits 4 and 13 my small appliance circuits? If so, I have a problem with a 15A circuit powering a sole 15A outlet, right? Either way, I need to run 12/2 and replace breaker with 20A, right? Then, I need to either replace single duplex outlet with a 20A version, or put another 15A duplex outlet somewhere else?
Question 3 - Is it OK for the garbage disposal to be on a 15A circuit, since it's marked as being 8.1A? Or is this required by code to be a 20A circuit?
Question 4 - So, I have one free breaker right now. I think I need to add a dedicated microwave circuit, and a dedicated garbage disposal circuit. That'll put six circuits in the kitchen alone. Is there any way that I can combine any of this, or do I need six? I need to squeeze out another circuit to put the garage & new outdoor outlets, and another circuit to actually make the bathrooms on their own circuit.
Question 5 - Related to question 4. Is circuit 4 needed to count as my second small appliance circuit, or do any of the others count for that? I'd love to free up circuit 4, and put those outlets on an existing circuit.
I'm really seeing the value of having a new home, AND getting to go in there while it's being built!!!
