The 12 volt outlets in my van are on all the time and I want to add a switch
to turn them off so I don't have to unplug every time.
My question is does it matter if I break the positive (red) line to interup the power
Or should I break the black line?
Is there a rule of thumb as to which one to break and run to a switch?
I believe either one will work - just wondering if there is a right (better) way to do this.
With 120 volt I break the black when going to a switch as the white wire (in most cases) should
never be broken, right?
In my 12 volt application the switch will be mounted against plastic so it won't be technically
grounded so that is why I'm asking if it is better to break the black vs the red.
Thanks
