I'm trying to figure out how to power my ADSB equipment but I feel completely electronics illiterate. Maybe you guys can help me.
I have installed a Uavionics Echo and a GRT Safefly gps to be in/out compliant. My intention has been to pull power from one of the circuit breakers on my avionics bus. Here are some pictures of my panel and behind the panel. These were the best I could do in tight spaces.
This is a pic of the circuit breakers and switches I have in my panel. The Avionics Master switch powers the avionics bus.
This is a picture from behind the circuit breakers/switch group above. I've outlined the avionics buss circuit breakers.
Here I have zoomed in and circled portions of 3 circuit breakers I presume are "hot" wires and go to individual pieces of my avionics to power those avionics. I would like to run my ADSB red power wire back to one of these 3 terminals to result in switched power to my ADSB equipment.
Here is a picture of what I presume is a grounding block. I presume that only because it doesn't have a thick power lead coming in. I presume that means it IS actually a grounding block and not a power distribution block. I would like to run the black ground wire from my ADSB equipment back to this block and share a slot with whatever is already in that slot.
Is my assessment accurate, and is there any way to test the terminals in question to see if in fact they are power and ground as I've described? I haven't tried to follow any of these wires back to either end.
If this is all good, do I need a new, higher amp, circuit breaker after adding the ADSB to the circuit. Let's say that I tap into the EFIS breaker because it might be the easiest to access. If I add another 3 amps of current draw to power the ADSB equipment, won't I be overloading the 5 amp EFIS circuit now?? I know I can add a 3 amp in-line fuse to the ADSB equipment downstream of the installed circuit breaker, but I'll still be drawing approximately 8 amps through that breaker. I'm not sure how I should solve this problem.
Ill stop there for the moment. Sorry for the long and clueless post!
Thanks for any help you can offer?
