Converter wiring question
A friend bought a used trailer without a converter. We bought the correct one but questioning whether the white wire is the hot or ground in this case. Are we dealing with 12v standards or 110v?

Hot and ground apply to the 120v input side of the converter. There, white is neutral, ground is green, and black is hot.
On the 12v DC output side, white is negative and the other colour is positive (blue in some converter models).
White is return on 120v wiring but hot on 12v wiring. That is what has me confused.
No. In RVs, DC white is always negative, if the other colour is black or blue or whatever. If the two DC wires are red and black, then now black is negative and red is positive.
The output DC wires of the converter do not connect to the "converter"! (ok, they do, but at the inner end)
They go the the DC fuse panel which has some lugs on it to take converter 12 v and battery 12v. If the battery wires to those DC fuse panel lugs are red and white, put the converter's white to the neg lug with battery white neg and put the converter's black to the battery's red on the pos lug .
DC wires do not have a "hot".
