Kitchen circuits


I am redoing the kitchen wiring in a duplex - the previous owner did whatever he wants with no regards to safety and code.

UNIT A

It has a single 20A circuit powering the refrigerator, microwave, dishwasher, disposer and two counter receptacles.

I am thinking of running two new 20A circuits, making it a total of three circuits to power those devices.

I am NOT entirely sure I will keep the disposer. I might get rid of it. I have had several tenants who likes to empty entire salad bowls or apple pies into it.

Right now my thinking is one circuit for the refrigerator plus microwave, one for the two receptacles in the counter, and one to be shared by DW/disposer. My question is, can I share the microwave and refrigerator or do I have to have a total of 4 circuits?

UNIT B

This one is a mess. Has a 20A circuit powering six hi-hat recessed lights, three down lights, dishwasher, disposer, two counter receptacles, and twenty four hockey puck line voltage cabinet lights - top lights, bottom lights, under cabinet lights.

So my plan is to dedicate a new circuit for all the lights in the ceiling - recessed and down lights, one for dishwasher and disposer (again not sure I would keep the disposer), one for the counter receptacles. That means a total of three circuits.

However, I am not sure what to do with those hockey puck cabinet lights. Do they need to be on a special circuit or can I hang them off the lighting circuit?

I thought those are low voltage at first, but I don't see a transformer, unless it's up in the attic in some hidden junction box...he just daisy chained them using #14 wires. Three in each cabinet, two inside the cabinet (top and bottom) and one under cabinet. Now if I decide to get rid of those lights, I don't suppose I can do anything with the three holes in each cabinet so I guess I have no choice but to keep them?

Kitchen circuits


Regardless of appliances you need two circuits for the countertop receptacles. This can power the refrigerator. A countertop microwave can plug into one of these. An over the range microwave needs its own circuit.

Lighting cannot be on the 20 amp small appliance countertop circuits.

Disposals and DW can typically share a circuit.

Jim in unit A, the lighting is already on it's own circuit. I am planning three new circuits:

20A - two counter receptacles
20A - refrigerator and microwave
20A - dishwasher and may be disposer

You are saying what I actually need to do is:

20A - one counter receptacle
20A - the other counter receptacle
20A - refrigerator
20A - microwave
20A - dishwasher and disposer

or are you saying:

20A - one counter receptacle
20A - the other counter receptacle + refrigerator
20A - microwave
20A - dishwasher and disposer

In the other unit, can I hang the cabinet lights on the same circuit as the down lights as long as total wattage does not exceed 2400W?

Thanks!

Option B is the best way to go in post # 3. I placed my fridge on the receptacles for the lower wall perimeter. I share the same gfci for my counter top microwave, that we also plug the portable dish washer into.

I kept the Disposall on the 15 amp that I originally ran for it. When I installed that in 2004.

Lighting for the Kitchen & Dining is on its own 15 amp circuit.

As for people trying to shove whole salads, etc down the drain with the disposal. They will still do the same thing with out the disposal installed. You will never stop renters from doing things they are not supposed to.
