Joe, I believe electric strength, clause 5.3, table 18, operation insulation, secondary to body or between independent secondaries, 500 V rms. It is my understanding that he accepted the exemption based on a permanent ground connection, and that the test is necessary if there is no permanent ground connection.

Can you elaborate on the reference above to the "500 VAC or 707 CDC requirement"? What clause does this requirement derive from? Was your CSA rep saying that this requirement applies even with a permanent ground, or was he saying that this requirement applies if you do not have a permanent ground?
