Dear All,

As part of our production safety tests, we check the millivolt 
drop across a connection in a 300A dc supply to a cell stack.  
In the past, we have only done that to one of the connections, 
and our maximum allowed limit for the drop has been based 
on results we've had in the past plus a bit of lee-way.

However, because of experience of our equipment in the field, 
we feel we should test all the connections in the 300A line 
rather than just the risky one.  But I have no previous results 
to go on for all the different types of connection.  I was told 
that there is a table somewhere of current/material/cross-
sectional-area/tightening-torque/temperature etc etc against 
mV drop.  Can anyone point me in the right direction, as I 
have exhausted my Standards, text books and company 
library! 

All pointers very gratefully received.

Regards, Mark
