Perhaps you've heard the myth that only fuse-based low voltage systems can be selectively coordinated. In truth, modern molded case, insulated case and low voltage power circuit breakers provide the performance necessary to deliver higher levels of coordination than some have previously thought possible. By understanding techniques for improving the short circuit selective coordination of low voltage circuit breakers, one can move beyond the myth to a more informed position.
This article encompasses only breaker to breaker short circuit selective coordination--not coordination with fuses and the protection of motors, transformers and other devices, or coordinated ...
