In the process of getting to know my boat electrical systems I have found a couple of instances where my boat does not seem to comply with some electrical standards, even though it is a fairly new boat built by a reputable builder. (2011 Jeanneau)
For example, it is my understanding that DC negative connections and AC ground are supposed to be tied together and bonded to the engine and running gear. On my boat it is not. There is no continuity between my shorepower ground and the dc system negative or engine. I have confirmed with other Jeanneau owners that this is the case on their boats too.
Another anomaly is my DC system. I am told that in the USA at least, it is not permitted to have a negative isolation switch on the batteries, rather it must be continuous. My boat was designed with both positive and negative isolation switches. My boat was built in the USA, (although there is some doubt about that!), and sold in Canada.
So I am wondering what standards boat builders use when designing and building boats, and what happens if they do not comply with standards in the country they are being built and sold in.
Regarding these 2 discrepancies, I wonder what their reasoning is for doing it the way they did.
