120/208V Residential?

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.

Hmmm. A not-head.

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.

I smiled when I read it.

Maybe he can do it part-time?

Thats interesting, I appreciate all the input from members of this site. I haven't personally seen any 120/208V service in Georgia.

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.

More likely in an apartment scenario.

I am in an apartment now but I have 120/240 service. I hope to go to a newer Apartment maybe I will find the infamous 120/208 . We did a few fire restoration apartment buildings at my last firm, all were 120/240.

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.

One of the most prevalent violations I see with this type of service is the improper use of 310.15(B)(6). Inspectors don't seem to mind it though.:roll:

IN the early 70's we did a 1200 amp 240/120 single phase service.

Beat me by 50%, and earlier too. We did a 800 amp in the early 80's
