Brian, Any significant impedance differences between these two supply configurations?

I've never heard of a Utility Company providing 208 "split-phase". I have heard the term "208 split-phase" many times from our customers who claim to have this but in reality what they have is 208 3-phase wired into a 230V split-phase receptacle but only using 208 Phase to Phase with the Grounded Neutral. In our EMC lab, we do not have a true 220 split-phase so we use 208 with a grounded neutral. It is the closest thing we have to test 220 volt household appliances like ranges, ovens, microwaves, and dryers. We know it is not exactly the same but close.

Good morning. There are oftensmall, legacy grids that you come across or hear about. I was recently told that some areas of the Northeast US have a 208 V, split-phase power system to some residences and small businesses. Still 180° phase-to-phase and presumably 104 V phase-to-Neutral. A specific area cited was "around Boston." Has anyone heard of or directly experienced this voltage system? Is it split-phase or was I misinformed and it's from a WYE connected transformer?
