Most seem to come with a 30A relay and I set them with “25A” wire as Jaycar call it. 41/0,3mm spec.
20A blade fuse, with inline fuse holder.
As the PSU will power a camping fridge, what about leaving the postie a chilled beverage in exchange for him managing the junk mail?

Edit: Rough calculations suggest 2 gauge wire for that distance, but realistically 4 will probably. work.
