| Subject: | com dual PWR/GND on two fuses? |
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

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.
