NEC art 210.4 and 210.5 seem to allow it and the CEC here in Canada
certainly allows it. For large residential highrises

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°
Essentially all residential electrical services in the US are 120/240
volt split phase services. Electricians call this single phase service.
As an electrical engineer, I like to think of it as two phase service,
with phases at 180 degrees. You will not find residential service
provided 208
Peter,
The idea of a 208 V split phase is unusual and probably not the case here.
The number 208 is obviously derived from a three phase system.
I believe the system you are talking about is a red-leg or high-leg three
phase system. Wikipedia does have a good review in this case (

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

This is usually called 208 V single-phase.
I'm still trying to clarify the specifics of the request.
