VPX-Pro Circuit Number
How many does the VPX accomodate?
My typical panel has about 15 brkrs and 10 slot fuse panel.
I am installing a VPX-Pro in my all-Garmin RV-7 project, with dual G3X screens, a G5, XM radio receiver, a full suite of Garmin LRU’s, electric trim, GTN650Xi, GNC255A, GMA245R audio panel, GTX45R transponder, TCW IBBS backup, the typical strobes, landing lights, interior lights, USB charging outlets, etc.
I am also installing dual PMAGS. The VPX-Pro installation manual expressly states that the VPX-Pro is designed to power PMAGS if the builder desires.
A VPX-Pro has 32 switched circuits. I will not max that out in my RV-7 installation.
Without seeing the actual design of the system referred to in the previous post, I am probably missing something. But it would seem that 32 VPX-Pro switched circuits, plus an additional 16 circuits requiring conventional circuit breakers would mean somewhere around 48 circuits.
I fully support the idea that everyone in the EAB world has valid individual reasons for designing an electrical system to suit their personal preferences. Furthermore, I definitely recognize and support that there are valid reasons pro and con for using conventional CB’s vs. Vertical Power or Advanced Flight Systems ACM electronic circuit breakers. So I have no interest in that ongoing and largely irrelevant to me debate.
I have already made my choice.
That said, based on my RV-7/VPX-Pro project (which I joke has turned into a demo platform for every Garmin product out there), an RV-7 electrical system design using 32 VPX-Pro circuits, and requiring an additional 16 conventional CB circuits, arouses some level of curiosity. It would seem to offer some additional features the builder views as enhancements that are not present in a more typical VPX-Pro installation like mine.
