how strictly do all of you follow the code on this issue,I have a 250 foot run to make the load at end of run will be roughly 25 amps and it is 3 phase ,now according to my fiquers I need to run some # 6 to stay within voltage drop range .The problem is that the sub panel that I was going to come off of is only wired with # 10 .
Have been in a lot of places where these long runs are made and the wire size is smaller than what is called for. So enlighten me as to if there is some guide lines or do you run wire called for,or am I mis fiquering the wire size
