So, do you guys think that I can safely test high-current circuits on the breadboard? Screech, have you tried higher currents? Anything more than 6A ?? Another thing ... howcome the breadboards are rated for voltage? I mean at the end, they're just a bunch of wires connected in a specific way, and wires are rated for current, not voltage. So ?! If indeed the rating is for voltage, then can anyone explain for me what is meant by "voltage" in this case!? AFAIK, there is no voltage between the ends of a wire!
