For the record, I'll check with my A&P tomorrow and post the info. Sorry for any misinformation: I'll try to straighten it out.

Ref David S's comment below, "If you have to mount it a distance from the battery in order > to reach it, you are compromising the crash safety that the master disconnect provides." I had also thought of that - but IF I put a ANL current limiter (BIG fuse) within 1 to 5 inches of the positive battery terminal, and then run a fat wire up to the instrument panel to the manual switch, even though the fat wire is longer than 5-6 inches, it is NOT "unprotected", so, should meet the guidelines that Bob Nuckolls frequently reminds us of. So, I/we should be able to mount the battery up close to firewall - out of reach (and not back by our knee) - 'cause we no longer have to have the manual battery switch near the battery.
