 Tim,I was going to say there is another soon to be operational as in, Elementary 3000, but it is not a DSV ;-) Hank

 I presume that even in the unlikely event of the double isolation failure which could create a short circuit current, that the DC mains are also protected as close as is feasible to the batteries by some manner of fuse or circuit breaker?

Sean,An alarmed device to measure leakage to ground on all polarities is a requirement for DNVGL, recently made a requirement for ABS, and was original equipment on Pisces VI. Fortunately, it is an easy thing to implement.

I understand that because negative and ground are separate that without a second fault on the negative side there will be no current flow, but why tempt fate? Maybe I'm thinking into this too much.
