This topic has probably been brought up here before, but through some searching I found nothing. (Sorry if I'm beating a dead horse
)
My question is, has anyone worked in a building that had 2 phase power? Was it POCO supplied, if so, could you explain the transformer hookup? (If overhead) What kind of disconnects / panelboards where used? I seen a few pictures of a smaller 2 phase service on a home inspector site. I consisted of 2 FPE panelboards, both feed with 2 hots and shared a nuetral. The meter said 2 phase, 5 wire. It had 5 wires for a utility drop. (Pics didn't show transformer hookup)
Just wondering if anyone had any information or examples on what a service consisted of. I know this is pretty much an obsolete system, but may well still exist in larger cities so it would be interesting to know how modern components, panelboards, etc are connected. I have seen diagrams and schematics for a Scott-T connection, and the theoretical aspects of changing 3 phase to 2 phase make sense, I was more or less wondering about the physical aspects.
Thanks everyone for any tidbits you can provide.
