UL508a to CE Marked Panels

[Tip DS]

I'm looking for input on exporting UL508a panels into the European market. I realize the safety requirements are based on the New Directive's Harmonized requirements, which are satisfied by the harmonized standards. All that said, I'm looking for the big differences & 'gotchas' that a UL508a panel producer might run into. For example, I know inspectors may insist they want to see ground wires as green with a yellow trace, where we usually use solid green wires. What other examples are out there?

I would suggest getting a copy of IEC / EN 60204-1, its not a light undertaking.
As of 2020 we no longer use uL508A / NFPA 79 unless a customer needs it.
Depending on whom your working for and the local AHJ a panel just needs to be listed, and even the NEC 409 does not require that.
IEC 60204-1 or a '204' panel as we call them can be designed to incorporate NEC 409 and 60204-1 = same panel for the US of A and for EU/UK export. But it takes attention to detail.

Thank you for that input, I appreciate it. Do you also find 62368-1 useful for power-limited (NEC class 1,2,3 circuits)? We make use of these power limited circuits frequently.
