Thank you to all who provided a response to my question. Your input and
comments are, as always, greatly appreciated.
Happy Holidays to all I look forward to seeing you at ISPCE in Dallas in May.
Best regards,

does not have
such a requirement. I wonder what evidence or research supports transient
voltages in secondary circuits?
Best wishes for the holiday season,

I have a client who has a secondary pwb that has traces and vias that

Per 61010-1 there is a requirement for spacing and/or dielectric
test, both depending on what the mains voltage is.

The simple answer is that you need to provide creepage and clearance
distances in secondary circuits to avoid arcing when the circuit is
subjected to the absolute worst case surges and transients that the circuit
might see. Since this can be difficult to determine, most people just use
the tables

The question is why is the mains voltage a consideration or
