The pictures do not show copper material on any of the connectors... Are you sure they are copper connectors?

They're all tin plated - supposed to be copper underneath but I can't say for sure.

What is the voltage & amps ratings ? Can these handle 120 volts AC , high amps or are these only low voltage 12 v ?

Yes I’ve also use them on 240 volts
