I'm reading here that several posters install the disconnect on the negative side of the battery rather than the positive side. Is the negative preferable? And if so, why?
Electrically it has the same effect. I prefer the positive side to stick with common convention of all switches and fuses on the positive side.
Although some RVs have multiple connections to the positive and a single cable to the negative that may simplify the install.
If it is an exposed knife switch that could short to ground it might be best on the negative.
My preference is an insulated switch on the positive.
