I have three loops of fastrack and legacy command. I will be running conventional and command. My layout is 8x16. I have three 180 powerhouses and three power masters. Each powerhouse has it’s own loop. Now how do I check the phasing for each? Does the rule for one common wire for the entire layout apply when three powerhouses and using bus wire? Do you need to connect each powermaster to the Legacy base. How to connect each power master to the Legacy base? If I decide to add an additional powerhouse for an extension can a tmcc direct lock-on be used.
