My company is looking for a test lab that can conduct contactor make-break
tests at 2000 vdc, 1400 amps preferably in North America.
Anyone know of one?
Thanks for your help.

I think you found it faster than me! I did an archeological dig today
to find it.

with classical device protection but data signal
Hello,
If one I.T. equipment is tested and have a report of EN60950-1, is the EN41003
report required for this equipment at same time? or, EN60950-1 is enough ?
why the standard EN60950-1 and EN41003 is on the LVD harmonized standards list
at same time?

We have been looking at equipment from Agilent that can run these radar
simulations although the other big test equipment manufacturers all have
similar product offerings. Your best bet is to get a hold of your friendly
neighbourhood Agilent rep. Make sure you are sitting down when they tell you

Hi Kris,
Normally the extra pairs are not needed. I have some jumpers that have
two pairs and I like the smaller size. Gigabit Ethernet uses all four
pairs though.
Over 15 years ago, in the late 80s when Cat5 cable was new and
dinosaurs roamed the earth, part of my funding at Bell Labs was

Kris,
2 pairs are used for 10TX and 100TX Ethernet. One pair is used for transmit,
the other one for receive.
You need 4 pairs for 1000TX Ethernet. All four pairs are used in both
directions.

Hello,
Does anyone know why an Ethernet cable has 4 pairs where only 2 pairs are
used: 1 for TX, 1 for RX.
Is it possible to use ethernet cables with just 2 pairs and not have
