Hi! In our previous T1/T3 designs we have used line widths of 12mils for 
signals from the connector to the magnetic i.e. line side of the transformer. I 
asked why 12mil line width and my colleagues mentioned that this is to meet 
immunity requirements. I asked our EMC engineer and he did not see a reason for 
12mil line width. So, it would be nice if somebody could shed light on this 
requirement. 
Thanks a lot in advance. 
Bob 

P.S I wanted to STOP for a moment and say that " SI-List has been very helpful 
and educational in shaping my career as an SI Engineer. I am grateful and 
indepted to all the people who post questions and to those who try to answer 
them.
