Peter,
I don't know where it's actually spelled out but, I've always checked electric
strength immediately following abnormals (blocked vent / rotor). This is when
insulation is most likely to degrade or fail.

You can screw them in or fuse each segment of the power backplane to limit the
power at each segment to insure 240VA.. We used to do both on a 10BaseT Hub.
Good Luck,

If you are asking wheather an enclosure with a keylock would be acceptable
means to prevent access, I would think yes. Why not? Anyone could carry a
screwdriver or a set of hex wrenches around on a keychain. I would think that
a key would be a more controlled means of securing access

Hello Charlie,
I don't believe Australia has any immunity requirements at this time. They
do require emissions testing and that these tests are performed by an
accredited lab e.g.. A2LA or NVLAP. Any electronic or electrical product

John,
Try BABT or TUV. First, if you haven't already done so, you may want to get
review a copy of TBR 21 from ETSI. I believe that they still offer free
copies on their website (below). Also, be aware that some countries have
contributed additional Voluntary advisory notes in the ESTI
