It all depends on how far away you're going to put the IPAC from the CP. If you want it six feet away, then yeah...you're going to have issues. I'd bolt it right to the CP somewhere.
At an average of 14 inches per input, you can get 21 strands of that length from a 25 foot piece. Now, not all lengths will be 14", some will be shorter, some might even be longer.
