[QUOTE="kerching, post: 533094, member: 11861"] Yeah, what he said. ^^^^ Basically (. I like basic ) Trip time depends on current flow Big current = fast time Small current = slow time Current depends on resistance Voltage is fixed So......low res = high current = fast time High res = smaller current = slower time Time has to be fast enough to stop cable being thermal damaged [/QUOTE]
