What is the acceptance value at NEC between phases to consider it balance case

You have a specific code to point to for that? IMO there is no way to get, or more importantly maintain a balance that close on a system supplying single leg loads - or 2 leg loads on a 3 phase system that are in any way intermittent or end user switched.I have seen many Scope of Works which is based on NEC and allows only 5% diviation.

But you understand there is no code to point to in that scope or spec.We had in most of Scope Work as Below
