NEUTRAL AMPS FOR BALANCED 2 Ph LOAD

[wch]

In an on-line article for EC&M magazine, Mike Holt shows a Figure with
L!, L2, N and calculates the neutral current to be equal to the current
in either one of the balanced 2-phase wires. The reference is to
"NEC 220.22.
I don't find this article in NEC.
I don't understand how this can be applied to a HVAC unit , say
208-1 Ph., with equal phase loading, with the load equipment
providing terminals for L1, L2, and GND.? (no neutral wire)

Not sure what you want to know. If there is no neutral than you have a different situation , I suppose, from what the article is talking about. You have a link or title to the article, date, year, etc

What? Do you have every issue memorized that you can come up with a 2004 issue on the article. :grin:

So if the art. is from 2004 then the code book is quoted from the 2002 code

Actually that was on the first page I looked.
