I don't have the schematics but I can guess. Looking at photos of the electrically driven AC compressor, I see no orange cables attached so I would say the compressor operates off the 12-vdc supply. If so, this is a heavy load for the 12-vdc to dc converter. Remember that 12 v is derived from the traction battery voltage through the dc-dc converter. Likewise, 10 A (120W) is a fairly heavy load all by itself for the 12-v dc-dc converter.
The kia niro manual shows a 40A fuse for power outlet 1, and 20A fuses for outlets 2 and 3 so each outlet has a separate fuse.
