Dear Sirs,
We have a doubt about the subclause 20.2 ' Fire enclosure' of the standard
IEC 60065:1998.
The clause 20.2 has three additional subclauses.
The subclause 20.2.1. is applicable only to equipment with open circuit
voltages exceeding 4 kV (peak).
The subclause 20.2.2. is about requirements for internal fire enclosures and
here we have a problem:
Must all the equipment have a fire enclosure or only those which contain
circuits with voltages exceeding 4 kV?
Best regards,
