Education is expensive. The unfortunate thing (as witnessed in this thread) is that people see this stuff on line and trust it as being current and correct.poker, their last manual for the isolator is dated 2005.
Don't mistake anything on the internet as being up-to-date, dead pages, legacy pages, forgotten pages, endure until servers go unpaid and shut down. And then, the internet archives still keep them alive forever.
It would be nice if they could update everything or if every web page was dated, but AFAIK their description can't be assumed to be any more current than the last manual, making ABYC 2005 the target to compare it to. But that's OK too. Since ABYC, like many technical standards groups, chooses to make their standards too expensive for the average reader to ever see them, "hoisted on their own petard" comes to mind.
Failsafes, idiot lights...I still believe what Edison said, that that AC electricity stuff is going to just climb right out of the sockets and kill everyone in the room at night. We could be just as safe as the Romans were, with lead water pipes. Hmmmm.....
Since we're talking about the ground wire, there shouldn't be any "flow" unless there is a problem (short, et cetera). As such, your alarm might not go off until there was a fault in the system. Ideally, I would think, one would want to know that there was a problem with the grounding of the boat BEFORE it was needed.Walt, couldn't you add a piezo squealer or buzzer inline with the diode bridges, so that if a diode failed and full voltage flowed, you'd get an audible alarm?
