When I looked at a 50 amp shore cord with moulded plugs at the rv supply its 6/3 + 8-1 its stw cord but it's rated for 50 amps. Does anyone know why it's rated 5 more amps ?

The same sized AWG cable can have varying current rating depending on insulation class - i.e. temperature rating.
EDIT: I forgot, the size and number of bundled cables affects ampacity too.
