Placing neutral(negative) for 12 volt with 110 volt neutral

[crg107]

Looks like in my converter 110 volt compartment all the 12 volt neutrals (white wires) are connected to the 110 volt neutral bus. What's the explanation for this. I'm adding a 12 volt plug and I'm surprised by this. Thanks for any information.

110 Volt AC: Hot, Neutral, Ground

12 Volt DC: Positive, Negative (negative ground to chassis)

110 V neutral is not bonded to ground in RV's at the RV electrical panel.

Here's some info: 120 VAC in your RV

If neutral and ground are bonded and you plug into a reversed polarity outlet then you, someone else, or your pet potentially could become the path to ground.

The two RV's I have now both have a separate 12V buss bar for common 12V negative connections. That buss bar is located near but outside of the panel/converter enclosure.

You might find various color wires used on the 12V side.

Talking to an electrician about this would be a good idea.

Thanks for the response. I have now more closely checked the 110 volt neutral bar and yes they are only 110 volt white wires and there are no 12 volt connections in that compartment.
