Can anyone give me some clarification on the following.
I am installing some Osram Planon Plus led light panels into a temporary building and have been told the transformers need to housed in an enclosure as they do not have the correct markings for BS7671 "max surface temperature under fault condition".
Im a mechanical design engineer and not disagreeing with the request but want to understand the regulation and why these off the shelf units need additional enclosures in order to be used.
Many Thanks in advance.
