If one applies the NEC to new equipment installations, how does one do it regarding equipment rated with FLA? If a circuit breaker rating based on 1.25 x FLA exactly matches a breaker size that is real, then 0.8 (80% rated breakers) will exactly match the FLA of the load. That seems to be a problem to me. If the load were ever to reach FLA the breaker will eventually trip. The same is true for 100% rated fuses. If I size a fuse for the FLA, then it will blow if the FLA is ever reached. Any insights on how one deals with this when sizing breakers and fuses?
