Hello,
I have an idea for something I'd like to build and I'm new to designing circuits so any feedback is greatly appreciated! I have 4 devices that each require 12v and they draw about 400-450w (33.3-37.5A). I'd like to design a power supply (or 4 separate) to power them. I'd like to be able to ensure that if one stopped working the others would continue and it would also be nice to be able to switch each one on independently. So here are my questions:
1. Would I be able to run all 4 on a 20 Amp circuit? I think I should be able to but I don't know that for sure.
2. Is it more worth it to only use 1 transformer? If so, would I still have control of each "channel"?
3. I uploaded a picture of the power connection, why are there 3 wires for both 12v and gnd?
4. Many things I've read said to double the 33.3-37.5A amps to be safe but to me that seems like it might be overkill?
Since I'm still in the early stages of this, that's all I have for now but thanks for helping me get this going!
