It just came to my attention that section 670.6 of the US National Electric Code 2017 requires a listed Surge Protection Device (SPD) to be on any Industrial Machine that has an Interlock, or I assume any kind of safety function. Is this true? The only information I can find on the internet is from the companies that make and sell the SPDs which can often be very one sided. Is there more to this story that I am missing?
Does the Surge Protection have to be listed? Are there specifications for the SPD? Is there a Surge Immunity Test that be used to validate and verify whether an additional SPD is required or not?
