RV-7 firewall penetrations for electrical cables

[John Courte]

My setup is with the battery on the forward side of the firewall, the PC680 with contactors in standard Van's locations. I have a SafeAir1 firewall pass-through. My electrical plan calls for a 6AWG wire to the main bus and a 16AWG wire to the endurance bus. Both of these wires originate somewhere near or on the battery contactor (possible use of a shunt instead of the MGL current sensor), so with this in mind and the ship already on the gear, where would you put the 3/4" hole for the power pass-through?

Pictures of your installs would be greatly appreciated.

thanks,
John

I am just getting ready to drill these holes too. I plan on following suit with this guy: http://www.jasonbeaver.com/rv7/rv7pictures/Scaled/20100514/CIMG1562.JPG

Hmmm, that guy looks familiar . I just copied the locations from Mike Bullock: http://www.rvplane.com/?categoryid=6&dayid=740

Thanks guys... I'm going to go with one on either side, high on the firewall like your examples. Although, I'm only passing one wire back from the MGL RDAC to the EFIS, so maybe the second FPT is overkill. A grommet and some goop might work there. But I guess it's better to have room in a pass through and not need it than vice versa, as long as it's sealed properly.
