On our panels, we use jumpers to tie several terminal blocks together to create a "bus" . IE. 24vdc+ digital, 24vdc- digital, 24vdc+ analog, 24vdc- analog, etc.
A couple questions.
1. When doing this, how do you prefer numbering the terminal blocks? I think it is nice to have all blocks of 1 bus the same number. Example TB1-1 is all24vdc+ digital, TB1-2 is all 24vdc- digital, etc. This does create a pain when it comes to terminal block numbers, you end up buying a bunch of extra number sheets to get all of the 1's and 2's. Does anyone else do it this way?
2. Another option is individual numbers, Ex. TB1-1,2,3,4,5 is 24vdc+, TB1-6,7,8,9,10 is 24vdc-. If using terminal block jumpers, this would mean potentially two wires per block. On your drawing would you list TB1-3 two times for two different pieces? What's everyones preference?
