Subject: AeroElectric-List: com dual PWR/GND on two fuses?
From: Werner Schneider <glastar@gmx.net>


Hello,

most avionics do have PWR and GND on two pins. My SL30 had even one used 
for the NAV part (3A fused) and one for the COM part (5A fused).

I have to replace it with a new 8.33, but just going for a COM right 
now, that one has as well 2 pins each tied together, PWR onto a 10A fuse 
(8W COM).

Is there any disadvantage, if I use the existing cabling with the 2x 
GND/PWR on extra fuses? Should I use 2x10A fuses (for a 8W com I found 
the 10A a bit high).

Thanks for your advice

Cheers Werner

Hi Werner

You may use the same cabling, connected to only one 10A fuse.
After installation, just measure the current when transmitting, and then you could
use a 7.5A fuse instead of the 10A.

Cheers
Carlos

I have my SL-30 (14V) on 5 amp breaker for Com and 3 amp for Nav. Actual 
use, from what I gleaned from the manual is about 3 amp on transmit for 
the Com side.
