Hello Brian,
In theory, a NEMA L15-20 with a sleeve could be compliant with European
requirements. However, theory and reality are going to collide with unpleasant
results. I tried this once in the past with a different North American
connector. In the end, I had to get the connector tested
Can the Recognized Testing Standards lists on the OSHA (NRTL) web site be
considered current ?
If not, what is the canonical and authoritative listing for each recognized

Hi Brian,
I am currently serving as the Acting Director of OSHA's NRTL Program, and
the list available on the OSHA website
https://www.osha.gov/dts/otpca/nrtl/list_standards.html is current. There
is a current proposal to add and remove several standards from this list
Interesting discussion.
The lack of prior experience with equipment such as this
industrial cut-off saw seems to come from folks who do not regularly work
with machinery and the Machinery Directive.
Having done some of this type of
A, yes. The line to line voltage is higher. I didn’t think of that. We
would also have a 400-480V version, but of course the 250 volt NEMA connectors
would not work, not to mention the hassle of trying to get them certified.
I always recommend the IEC60309 connectors but everyone complains
And it's even more fun when the other guy that doesn't do it is an EU company
being compared to US companies importing into the EU that have to do it.

Pete,
I think you have a good understanding of the situation. You are right; they
avoid doing EMC testing because of the cost, but we don't do business that way.
When we offer to perform EMC testing on their products for free, they say NO
because they would rather be ignorant and ship products
And the dreaded - the other guy doesn't do it why are we Heavy sigh.
By the way not too long ago I saw the pragmatic answer to that.
Company A built a product. For whatever reason Company B challenged the EMC.
They tested at a lab and sure enough failure. I don't know how badly it failed
but it
