I have a question for you guys. I have 480v supply 3 phase and I need to use a transformer to get 240v 3 phase for 3 machines. IF I use a 75kva transformer I have enough power for the three machines. If I run a OCPD on the primary side do I need any on the secondary side ? http://forums.mikeholt.com/images/smilies/confused.gif
Each machine has a main breaker as the main power hookup.
These are plastic injection molding machines.
Thanks
