Almost ever set of plans that comes across my desk has a spec or a note saying to size the conductors to prevent more than a 5-3% voltage drop. I have yet to see one of my competitors actually do it on the jobs that I lost to them.
The problem is if you bid the jobs that way you wont get the work. Its only when the engineer has actually done their job and sized the home run accordingly that it gets put in everyone’s bid and wired that way.
