Should be an easy one here... I have a 3000 Amp parallel service to do on a building I'm starting. I've done larger parallel services before, and have always observed making sure that each conductor of each respective phase is the same length as its counterparts. Typically, when I ran underground conduit to supply these services, I'd have my trenches dug extra wide, so I could eat up some of the difference in run length caused by having to stack conduits going into my gear.
For this service, though, the transformer is literally 15 feet from the building, at a 45 degree angle from the main switchgear. I did what I coukd, but I have a four foot difference between the shortest and longest run. That is a ton of slack to eat up in the TC. Anyone know if there is a threshold in the code for when you have to start worrying about inbalance? Or am I just stuck with having to have an ugly cabinet?
