I've tried searching and haven't found the right thread yet and I'm sure this is a simple question that I'm probably just missing some important element of information on. So here goes...
I've got incoming 220 single phase going into my RPC with 220 3ph output. Everything is fine and works well but I need to step up at least part of the output to 440 3ph.
My RPC is wired with incoming 2 hots and a ground, no neutral. Coming out of the RPC are 3 hots and a ground. Now, when I'm looking at a step-up transformer, there's this pesky problem of needing a neutral for the second leg of each phase. From everything I've read, I understand NOT to steal the neutral from my single phase and try to use that because of funkiness that may ensue.
So, my question is, where do I get the neutral needed to step up the 220 3ph to the 440 3ph and then I what do I do with the neutral coming off of the secondary side of the transformer because I'm guessing it needs to remain separate from the other two neutrals in the system.
If someone can point me to a thread, that would be great because I don't someone to have to explain this again. I just can't find the earlier explanation.
Thanks,
