hello, i hope somene here can help me. let say i want to calculate max
current through brass terminal block like this
one:http://www.cableaccs.com/image/brass_earth_terminals_accs-1.jpg

I understand that brass conductivity is 30% of coppers. But this profile
hace wholes where wires come etc. How can u calculate what would the be
the rated current?

I suspect there are too many variable to come up with an accurate
calculation. For instance, is the block mounted to a chassis which will heat
sink it or not? AC or DC? Determining contact resistance will be a
problem.

If it was me I would just assume that I max was approximately equal to the I
max of any one wire that will fit into it.
