The lower level of my large(25x25) layout will be TMCC only. I will be using 135w and 180w bricks to power it. I have one of each from old layout and will likely add others as needed. My questions are:
What is the difference in TMCC between a"block" and "power district"?
Do I need to isolate each block/district for each power source?
What is the best way to connect the common and hot of the Powerhouse lead to gargraves? (on my old layout I used a section of lionel track and the powerhouse lock-on, I like the quick circuit breaker
On the TMCC lower level there are two mainlines, each over 100' and a yard/terminal area with over a 100' of track
I'll be using 12-14 ga. buss to the block with 16-18 ga drops.
Your help/advice/comment are appreciated.
