Another thread got me thinking about this. So clearly we have fast acting vs time delay fuses, thermal magnetic breakers, hi mag breakers, adjustable trip settings........So who or what determines what settings are acceptable to avoid conductor damage? Article 240 just seems to say "conductors shall be protected against overcurrent" with no further details. Also, OCPd's are not required to be listed, so theoretically they dont have to meet any standard. So is there anything preventing me from making a circuit breaker that has an excessively long time delay? What am I missing?
