Yeah, I typed 'not' in my head but it did not reach my fingers.


That is a common occurrence. I find myself doing that often. I only find the problem when I proofread it. Must be some sort of psychological issue.:)
 
In a high rise I have never seen it any other way then a 3 phase service suppling single phase units.

The areas I was talking about are typically 3.5 story brownstones or similar buildings.

The under ground network is often fed by multiple transformers located underground and spread out, the result is very high fault currents in theses homes.

Virtually all of NYC's residential and commercial distribution (overhead or underground) is the same. 240 is rare.
 
Frankly, I didn't seem to understand where 208 device couldn't be used as a two pole source were required!.
They certainly can. Wire just as you would a 120/240v service, just know that 240v devices will only receive 208v.
 
In my experience 800A is the typical maximum for 120/240V 1PH 3W service drops. One of the larger POCOs, in this area, refers to 120/208 1PH 3W services as 'networks'.

Here the cut off seems to be 400 amps for single phase and yes they call those 208Y/120 distribution systems networks here as well.
