Hi,
Silly question, but if you are testing a Class II double-insulated supply with
no earth, would you simply ignore the Common Mode parts of the test eg Surge
Immunity (Live to Ground/Neutral to Ground ignored), or is there some other
arrangement to be used?
Many thanks,
Regards,
Very helpful, thanks Brent!

IIRC, most of the basic principles were explained, with illustrations, in
Albert Smiths early IEE papers published in the 1980s.
I only had a paper copy of those when I started experimenting with his
swept-frequency site calibration methods in the late 80s (at HP) and I

Hi,
please see IEC 61000-4-5 clause 7.3, which states that no surge is applied in
case of no ground connection.
This is also repeated in many product standards, at least CISPR 14-2 comes to
my mind.

Hello Amund,
The FCC do perform market surveillance on certified products and every TCB
must also perform market surveillance on 5% of the devices they have
certified.
The TCB must report the findings of their surveillance to the FCC each year.
I think the results are not openly reported, but I
