The ultimate issue is what safety issue occurs if the contactor fails to open
or close when it is supposed to? If there is no safety consequence, then the
contactor contro
constitute a safeguard
and must be “reliable,” and must meet the intent of the standard.

I am using a Panasonic
“Agreement is usually a compromise for both sides.”
Unfortunately, the process denigrates science and engineering (but saves face
for both sides, especially the certification house).

Interesting. The test engineer at the NRTL (not UL) I always work with always
says we (the lab and the client) must always apply sound engineering judgment
when applying standards when something isn’t completely clear or
straightforward in the standard. An

I only pilot paper airplanes and this isn't my area of expertise, but it looks
like this potential requirement originates in NEMA ICS 5 "Industrial Control

At 110VAC the contactor coil draws 30mArms.
The coil contacts are wired to a PCB via a terminal block plug and socket
