contactor or fuse position in circuit rules - WHY??
Manuals advise contactors and fuses to be put on the B+ end of the circuit not the B-
Why does it make any difference, the whole lot is connected in series so I can't see how in physics it matters
Theres obviously something about electronics I don't understand, grateful if someone can explain?
This is the question thread if anyone can help, maybe mod can remove the other one which was double post
As you say it really doesn't matter, but when it comes to vechicles minus earth (ground) has been the standard for a long time and therefore it's easier to put fuses and such on the plus wires.
Though of course a high-voltage traction battery should have no business at all with ANY pole connected to the vehicle frame/body! Traction batteries should be completely isolated within the vehicle for obvious safety reasons.
But as Johnny J wrote, that does not stop electric vehicle manufacturers from placing fuses and the likes on the positve pole of the traction battery, just out of good old familiarity...
