I went ahead and used the large red cable under the seat to supply a Renogy 50A DCDC charger limited to 30A and it’s been working perfectly fine. Any idea what the disadvantage would be if this originated from SA8 instead of SA3?
Merely a lower amperage fuse and possibly thinner gauge cable
In my case SA8 is fused at 50a and it feeds a 10mm cable in to the pax seat area.
It’s been running my Ring RSCDC50a without issue
