Diagram comparing coordination failure and selective coordination between protective devices in an electrical system. The top section shows a 32Amp circuit tripping a 63Amp breaker, causing upstream devices rated 125Amp and 160Amp to disconnect unnecessarily. The bottom section demonstrates selective coordination, where a 125Amp device isolates the fault without affecting upstream devices rated 250Amp and 600Amp.
