Do you use white=negative, black=positive for DC in your RV?

Even worse each manufacturer has a different color code scheme

Winne / Itasca is mostly consistent with
Black/White for 110VAC and Yellow/White for DC

Me I stick with Red/Black for DC
and
Black/White/Green for 110AC

All the dozens of wires I have added follow my color codes
DC - Red/Black +/-
Never Black being Positive and I do not use Yellow or white for any DC connections
AC - Black/White/Green
Hot/Neutral/Ground

There are exceptions
The 4awg and 2awg welding cables used for DC + lines
But I did add red heat shrink to ID them
