Tandem breakers on new install.

I have mentioned this before, but I'm all about the sub panel for most houses now. Nothing more tedious and annoying then making up a 40 space full/mostly full panel with mostly AFCI's. Kill self 😞
🤔🤔
I'm not sure what you're accomplishing, unless a subpanel makes some of your circuits disappear 🫣

I like sub-panels too. For a multi-story house that often is easier than running all of the circuits from the basement or garage. In my house everything came from a single panel in the basement. A sub for the second floor would have been much easier. I ended up adding a sub-panel in the garage because the garage circuit was only 15 amps and my compressor would trip the breaker about every third or fourth time it started.
 
I don't know. All I know is I mention the word sub panel and a bunch of the branch circuits disappear 😶‍🌫️
ah a cost factor makes HO or GC rethink adding all those circuits
After I installed it a 2 pole generator interlock, 2 pole irrigation pump, and a 2 pole cook top were added to the job.

Instantly 6 openings disappeared.
I like the 2 pole tandem for a lot of these. Get a 30/50 for a dryer/range, a 20/30 for a pump/Water Heater, a 20/50 for a pump and EV and 6 becomes 3.

This. #2 SER AL is $1.71/ft. 12/2 NM-B is .40/foot. When you start hitting 5 or 6 home runs to the same area, a sub panel starts making sense.
Also saves you from having to run down 2 flights of stairs when the teenage daughters try and run multiple hair appliances at the same time.

When you start looking at kitchens, with an electric range and all the signle circuit appliances, #1 or 1/0 SER is cheaper than just the 6/3 copper for the electric range alone.

I used 75' #1/0 Al SER for my garage sub-panel I think it was about $1/ft.
 
I guess I need to say I'm joking guys. We were talking about tandems, AFCI, not being able to use tandems etc. I said I like to add a sub to reduce the #, of circuits. Yes that's the number of circuits in the main 🙄
I've wired some that I wish I would have added a sub because I maxed out the one panel.

My own house, for one. It's only 1,000 square feet and had a 20 space panel when I moved in, but change is a-comin'

It's a 30/60 and it's got about 15 tandems in it. So far I have only 7 dual function breakers in it, for 2 lighting circuits and 5 kitchen circuits. Everything else is with existing, or it's outside and garage
