Rear ground already taken up by van electrics

[VANLIFETerry]

Hi All,

Was running the Earth ground cable from my Victron Multiplus but it appears the ground connection I was going to use at the rear driver side is already taken up by the van electrics. Am I okay to still earth here or should I find another location? Given this relates to the 240v multiplus system I’m not sure if it can share a ground point with the vans 12v electrics? I’m sure I read somewhere that the 240v must be at least 30cm away from the 12v but I could be misremembering! I’ve done this already with my cable routes/conduit.

Can I still ground 240v here?

@Dellmassive your advice would be greatly appreciated!

Cheers,

You are fine to share ground points. The 30cm spacing I really don't think is a must in terms of the setup more for being neatt and keeping things separate. Apparently it reduces noise and interference but I really don't see the need in a van.

Yes you can share that chassis bolt.

Or you can drill a new hole on the frame and add a new nut and bolt.... With cleaned metal.

the 3kva bolted in well.



i kept the NEG as short as possible and made a new ground connection, using a flapper wheel to remove all the pain for a good connection.

we are expecting 300A plus to be going over this link - so it needs to be good.





next up was to re-do the seat base . .




i was using the seatbase at the main NEG. . . so removed all the paint from the 4x bolt holes.





this wire brush drill attachement worked a treat. .



the idea was to spread the NEG load across all four seat...
