I have a utility feeder with (1)350kmcil aluminium conductor per phase. We wish to make a tap from this feeder to a 600 ampere distribution panel via a junction box. I would like to know when the NEC come in to play relative to these tap conductors. I would like to use parallel 350 copper for a tap to the 600 ampere panel.
I understand the utility has there own requiements and through historical data my feel it unnecessary to provde paralell 350 to feed this area of service.
Thank You
