Very useful link. This particular piece of equipment is not listed, nor is it CE marked. The equipment will not use the split phase connection at all times, so the 2nd line will not be grounded at all times... that's what makes it a special case, the line will not always be a neutral...depending on jumper configuration.
Foreign... as in not in the USA, I imagine.
"Split-Phase", in this context, is a term that I clearly and absolutely, do not have an understanding.
Yes, I understand the term in the context of "Split-Phase Motor" - which has nothing to do with 120/240 Single-Phase-North-American-Common-Supply. "Split-Phase" shows up in the NEC only as refered to a "split-phase motor" and only shows up in IEEE 100 as refered to "split-phase motor".
Yes, I am familiar with coloquial use of "split-phase" meaning 120/240 SPNACS - however, I thought it meant a connection that took 3W 120/240 (two hots and a neutral) but in the OP context, that don't work. So, I'm lost - or as my trusted peer group compadre would say, "Worm - you're all wet."
So, I ask for an education. Specific Q's:
"split phase equipment that operates at 208/230V single phase" - Does this split-phase equipment take two hots and a neutral, or just two hots, when connected to 120/240 SPNACS.
"The equipment can also accept 400V-Neutral split phase connection" - My understanding of European 400V is: Wye connected 230V L-N. So, is the connection two hots (400V L-L) and a neutral (230V L-N) or a single phase connection 230V L-N?
Truely, I'm just looking for an education on the term "split-phase" as referenced to 120/240 SPNACS and European 400/230 Wye.
