I went through the process at my last employer.
I thought it was a good idea.

If a problem arose, it was traceable and could be remedied.
2) Better stuff? Perhaps. But

As they were a lower cost circuit breaker we spec'd them into a telecom

While your message indicates that the FCC may not have a problem
with the 'assembled from tested components' concept, it does not
mean that the end-product will actually meet the limits.
Poor routing of internal cables, insufficient grounding, just to

I am trying to find a second-source for a TVS (Transient Voltage Suppressor)
that I now use to meet the 61000-4-5 1.2/50us 1kV transient.
Surface-mount, small(?) form factor
Anyone have any successful/favorite TVS that'll do the job. . . ?
Thank you in advance.

Go to the UL link I attached, go to 'keyword search' and do a search on
'Communication Circuit Accessories'
It'll give you a whole list of companies.

that is using an 'accredited' lab, then so be it.
(If a company goes through the expense of creating their own site, it
may be worth to at least have some 'minimal' - if that exists, amount
of accreditation).
