All of the Aeroelectric 'Z' diagrams show the ANL current limiter mounted
within 6 inches of the starter contactor. I would like to mount mine on
the right side of the battery on a RV9. What wire size would you use ? I
am using the B&C base with a 60A fuse.

The 6" figure for acceptable runs of un-protected wire
is a rule-of-thumb long practiced in certified aviation.
Admittedly, it's most often applied to small wires . . .
the kinds that come off the busses to supply varios
accessories. The alternator b-lead is a major distribution
feeder and is one of the biggest wires in the airplane.
Major feeders are not generally "protected". This practice
is supported by decades of service history and failure
data.
The goal is to put any form of circuit protection for
a wire as close as practical to the source of the energy
that will burn the wire. Likelihood that departures
from the 6" 'rule' is going to cause you grief in the
future is exceedingly small. My personal choice for
all fat wires in closely located battery/bus/alternator
installations is 4AWG.
