Larger fuses only relocate the symptom or hide the problem they are not the solution.

current flow through a resistance causes heat, more resistance or more current equals more heat. Fuse blows cos it gets too hot because the current it too high for its resistance.

bigger fuse, less heat for the higher current... Problem is that higher current is now causing more heat somewhere else... ? Where, nobody knows...

plastic insulation melting? Does somebody smell smoke?

dont just increase the sizes of your fuses gents, they are set at a value for a reason.

The current flow doesn't make sense. Best bet is to disconnect stuff and see what happens to the current you are measuring. It really sounds like a dead short somewhere that isn't 100% of the time, like a wire pinched and occasionally rubbing.

New no1 suspect - trailer wiring.
Camera connections all inspected and traced as much as the wire I can without finding any exposed or rubbing points. I did find a connection that hadn't been soldered and insulated - but alas not the source of my short.
