The existing condition is a single phase system. There are 3-500kcmil & 1-#2(ground) cables in a 3" conduit. The feeder run is overhead and underground from the main switchboard to a power distribution panel at approx. 300 ft.
Now, the plan is to convert it to a three phase system in a very cost effective way.
Is it a Code violation to run a new 1-500kcmil in a separate conduit parallel to the existing feeder run?
Any suggestion? Please help. Thanks.
