The "Electrical circuit failed: have your vehicle repaired" error pops up every time I start/turn the ignition on.
I ran a diagnosis with Diagbox and I get: B1601 15 -> Central power switch positive (+CPC) relay control fault.
I own a Peugeot 508 hybrid 2012 ( 200 Horsepower model ).
Today I got some mechanics to try and fix the radiator fan since it's not working.
They tracked down the issue, suggesting I should replace the fuse box located near the battery because they say there's a relay there that's not working as it should.
So, they must have broken something in there.
I tried deleting the errors 3 times with DiagBox and also did a battery reset procedure.
What's wrong and what can I do to fix it?

Here is the fault descriptor for this code, but post up your VIN (automasked on post submission) so I can check this is the same for your vehicle, just to make sure.
So I would first check and test all the fuses in the supplies protection management unit as these power various equipment, but if the garage have tested it and are confident, then I can't do much more than provide the code description for this fault for you.
