[QUOTE="rich1, post: 555264, member: 35020"] Sadly we won't have the Regs book to hand in the exam, only the on site guide. Looking at the charts I see that 300A is just at the point on the 32A line where the magnetic trip meets the thermo trip on a class C and is nowhere near the line on a 32A Class B. Am I right in reading that charts that Class B 32A breakers open instantly at 160A and above where as Class C open instantly at 320A and above? [/QUOTE]
