Went to install some light cans in the dining room yesterday only to discover that the existing wiring structure is a mess. And before I go make things better, I want to be sure I’ve got my info straight.
Lighting — Currently kitchen lights and dining room lights are on same 20a circuit with no-ground AC cable and some bits of 14-2 NMB wire tied in at various spots.
Proposed change is to switch to a 15a circuit with 14-2 throughout, also to add some low voltage under cabinet lights. (New scheme would have 7 dining room light cans and 3 kitchen light cans, plus the under cabinet stuff)
Question – Can the same lighting circuit serve both the kitchen and dining room? I’ve seen conflicting advice on whether the kitchen light circuit can serve only the kitchen, or beyond.
Receptacles — Currently the same circuit that’s powering the lights, also powers 3 small appliance/counter receptacles in the kitchen, 2 receptacles in the dining room, 1 receptacle in the living room, as well as the light at the top of the stairs one floor up from all of this.
Proposed change is to put the kitchen small appliance/counter receptacles back on their own 20a circuit, move the living room receptacle to a new circuit that serves only that room, move the upstairs landing light to the circuit that currently serves the two bedrooms upstairs.
Question – What to do about the dining room receptacles? There’s a mention in the NEC that allows the pantry and breakfast room to share the circuit with some kitchen receptacles. But I’m not clear on if this would include the dining room (hey, I’m not wealthy enough to have a room just for breakfast :), AND whether this shared circuit refers to one of the two required 20a ones from the kitchen, or the optional 15a one.
