For the new kitchen I have the following appliances and outlets. There are many ways I can combine them together or keep things separate. What do you think would be the ideal way to allocate the following to breakers without wasting breakers? I have enough free slots (6) in the main panel plus an overflow subpanel (20), but I don't want to use more breakers than optimal, since the wire runs to the subpanel are much longer.

• 50A induction cooktop, 50A oven, and 12A dishwasher will have their own breakers.
• 3/4HP Garbage disposal + possible future GD in island (thinking to put these two on one breaker since I might never install the island GD).
• Main 36" fridge. The manual says it can go on a 15A or 20A breaker, but I can't find the amperage specs anywhere.
• 400W warming drawer in island. The manual says this should be protected by a 15A breaker, but doesn't show the amp specs.
• Undercounter refrigerator, 2.3 amps.
• Undercounter wine cabinet in island, 2.4 amps.
• 2 or 3 outlets in island (small appliance circuit).
• Several outlets on counter #1 (small appliance circuit).
• Several outlets on counter #2 (small appliance circuit).
• Electric opening-assist waste drawer, 1.7 amps.
• 6 Glass cabinet illumination lights.
• Undercabinet lights.
• Kitchen recessed lighting.
• Island pendant lighting.

 

400 watt warming drawer 400w/120v = 3.5 amp (approx)
Should be installed on a 15A circuit for protection but does not have to be on its own circuit.

fridge approx 1200 watts 1200w/120v = 10 amp (approx)
Fridge can be on it's own dedicated 15 or 20 amp circuit. I'd use a 20A

undercounter fridge/wine cabinet/waste drawer/warmer drawer > 15A ciircuit
all lighting on its own 15A circuit
island receptacles > 20A circuit
counter 1 > 20A circuit
counter 2 > 20A circuit

 

Excellent PJMax, I like your plan. That would consolidate the lightweight fixed appliances while allowing full power draw from the counter outlets.
