Kris,
If you have an electronic copy of the standard, do a search on IT and
determine if the clause is applicable. For instance, if you do so with IEC
60950-1, 2nd Edition, you will hit on 1.5.8, concerning components connected
between line and earth. Not applicable. Next is a installation

Mr Woodgate,
I have noted a CTL decision for IEC 60335-1 that seems to indicate that
CECC 42200 certification is also acceptable. Also applicable to 60950-1 ?
Also, I am looking a the spec sheets for several IEC 61051-x certified
MOVs and have noted that the rated voltages do not seem to
The time to
repair an earthed IT system is quite short compared
to the time for long-term creepage distance
deterioration.
This may be so but I have no experience. I imagine almost no one in the US has
even seen an IT system. My only encounter was in a hospital surgery suite.

Here's the best info I found regarding definitions for interharmonics...

Mr. Nute,
Would your assertion apply to both Class I and Class II construction ?
I am certain that you can see where I am going with this question...
A related question. I have tended to discourage Class I construction for
power sources that would be attached to an IT power system. Is this not
Hi Bob:
Thanks for your thoughtful response.
You said:
The working voltage increase would tend to approximately double creepage
distances, but again these are mains to earth distances, not mains to mains.
This can impact designs though.
Creepage distance requirements are based on

I have no info on the EMCO 3110, only the 3100B, which info is available from
ETS/Lindgren. I have the Eaton version of the EMCO 3146. It is called the
96005, and is identical in construction. Antenna factors follow, from a 1988

There shouldn't be any problem with what you want to do. This is a
