 Posted: Wed Jun 17, 2020 4:00 pm Post subject: Z-11 ground avionics bus question |
 |
|
I hope the answer to this question is not too obvious;
On Z-11 (and others), the connection between the instrument panel ground bus and the avionics ground bus is designated 5X20AWG. What exactly does that mean?Â
- Do I take up 5 tabs on my ground buses with 20 ga wires?
Thanks,
Ben

Yeah . . . 5 separate strands of 20AWG as long as
you have the spares . . . otherwise . . . plan-B.
The individual strands are easy.

Hi Ben,
Have you seen Figure 18-17 in the Aeroelectric Connection Book? (and the accompanying text) Note that in Figure 18-17, "(Instrument) Panel Ground Bus" means forest of tabs aft side of firewall in the case of a tractor and in the cabin in the case of a pusher. The term "Panel Ground Bus" has been changed to "Firewall Ground Bus" on newer dwgs like Z101.
