Hi,
in my installation, in extreme situations when multiple failures occur, shower waste water would run into the multiplus from above.
In this situation, I think the RCD of AC-IN would trip fast enough.
But I'm afraid the multiplus keeps running, switching in off-grid-mode, AC-OUT would still deliver power, which could run though the waste water, the person taking a shower towards fresh water/grounding.
Is this valid, or would the power run towards the grounding of the multiplus (6 mmĀ² on the dedicated ground-screw as well as 2,5 mmĀ² on AC-IN)?
What do you think? Is there an easy way to protect against this power hazard?
The risk of this hazard to occur is nearly impossible because of my house installation, but my question must be very relevant in case of marine usage.
Bye
Alex
