Wiring Unlimited - floating network page 62

Hi,

Ive searched the forum but could not find this question asked.

In Wiring Unlimited (rev 01 - 03/2023) chapter 7.5, about mobile IT Networks page 61/page 62.

It states that IT Networks are not connected to ground (therefore have a floating neutral) but in the images to this subject, in the middle image there is a connection between source and ground.

it proceeds to say no current will flow. But if i'm not mistaken, current will flow through body, through ground to source if there is such a connection als shown?

Thank you in advance, and if this already asked on this forum please redirect me to the topic.

Yes, the middle picture in the top row of p. 62 and the first (l.h.) picture in the second row appear to have been transposed. Maybe @Guy Stewart (Victron Community Manager) can feed this back?

Yes, that is it. Thank you for pointing that out.

I think it should indeed be fixed. People use these images as installation diagrams.

It's a ground/neutral loop, not a power loop, so no problem / danger there.

Danger will be if the human touches the brown / fused wire.

Maybe my terms are not very well used, sorry, not an English speaker.

Thank you for your reply.

An IT network does not have a neutral-ground bond if im not mistaken. So that would be incorrect in referred image.

I understood that to create a 230v potential using an inverter with floating neutral, both neutral and live carry 115V. This would mean the neutral in this image would be harmful if such a ground connection exists in an IT network, correct?
