Hi Nev,
I haven't found that info anywhere but I have had to repair several FT817 where the supply was missing from the connector. The culprit was a dead teeny weeny SMD 0402 10 ohm resistor feeding the acc socket. Had to pull the board out to find it.
If I do the maths on a 10 ohm 1/16th W resistor I calculate you wouldn't want any more that 8mA running through it for any length of time.
If you're up to it I'd consider this mod http://vk4ghz.com/ft-817-12v-acc-mod/ as a way of protecting your rig. You could add a low value, low power resistor in series with the wire for a bit of extra protection.
