Jim,

No Standard (that I am aware of).  Just an internal request.

Subject: RE: AC Open Neutral Test

Jody: I'm not familiar with a particular test for this, although I am familiar
with the issue.  What standard and clause are you referring to?

Subject: RE: AC Open Neutral Test

John,

Thanks for responding.  I gather from the lack of replies AC Open Neutral is
not a popular test to conduct.  However, the question of power systems remains.

Can anyone provide the maximum voltage a product could potentially see in the
event of an open neutral condition in other parts of the world for pluggable
type equipment in residential or commercial use?

Also, is anyone aware of any documents that specify the power distribution
systems around the world?  From Annex V of IEC 60950-1  it appears IEC 60364-3
describes the different systems but does not include voltage levels and phase
relationships.

Best Regards, 

Jody Leber

Yes, it's different. Single-phase 230 V with earthy neutral; the way the
connection between neutral and earth is made varies with country or
distribution system. Three-phase 400 V with or without neutral.

No 'V-0-V' systems as used in the Americas.
