Bob,
I'm not quite sure what you're trying to say here.
I think when Bentley reports wire sizes in mm they are referring to the
cross sectional area in square mm. I don't think they are using the diameter
of the wire in mm.
As Harold pointed out the Bentley on page 97.4 says:
"Wire Size/Color
American Wire Gauge (awg) as shown, or
metric cross section........"
I believe a cross section is measured by its surface area, in this case
square mm.

For instance, in the discussion that generated this wire size question,
we found that the Bentley referred to two wire sizes that supply the fridge
set up and the auxiliary battery set up. It shows a 6.0 mm wire for the
auxiliary battery set up. If we interpret the 6.0 mm to be a diameter, then
according to your numbers below we would be looking for an AWG #3 wire to
the auxiliary battery compartment. A #3 AWG wire is almost .25 inches in
diameter not including the insulation. That's huge. I don't think you will
find that size wire in the auxiliary battery compartment. However, if we
interpret the 6.0 mm to be a cross sectional area of 6.0 mm, then the wire
gage we would be looking for would be a little larger than #10 AWG and would
have a wire diameter of about 1/10th of an inch not including the
insulation. I think that is much more likely to be found in the auxiliary
battery compartment.
Perhaps I am wrong about this. Anyway.... what do you think?
