500 MCM

(OP)
I'm a mechanical designer but we have a project where some of the power transformers are under my contract.  My specs. use the terms #6/0 and #4/0 which I'm familiar with but also refer to " 500 MCM" connectors which I am not familiar with.  Can I get the short version of what type or size this refers to and a source?

500 MCM (now referred to as kcmil instead of MCM) is a wire size meaning 500,000 circular mils.
Typically in the US it goes

smaller sizes 1 to 32 or whatever AWG

Just to note, that the area is the area of copper conduction, not the total area of the conductor.
