 |
|
I purchased the Panel Grounding Hub because it sounded like a great device and because it comes from Bob. But since getting the hub, I have read about concerns about grounding avionics through the hub because of current limitations of the individual pins and the potential of exceeding the current capability of the hub and the 4 or 5 20 ga ground wires run to the Forrest of Tabs. Something was also mentioned about all ground wires not being equal such as when a 16 or 18ga wire is split into two 20ga wires for insertion into the hub.
I understand that low power grounds such as from LED Panel lights are a good choice for the hub. But I am installing a g430W, a SL-40, a GTX-327, a PS5000EX, Dual GRT HX Displays, the GRT Autopilot when it is released, a AFS Sport AoA, GRT EIS and a TruTrac Turn and Bank indicator. Some of these individually have fairly low current requirements but as a collective, the current is considerable.
I need some advise from the experts as to what can be run to ground via the hub and what needs to be run directly to the Forrest of Tabs. I would optimally like to utilize the hub as much as possible merely to control the wire runs.
Thanks for your help,
