Hey guys. :beard: I am in the process of building an electric brewery using a beaglebone black as the PID controller. It will be controlled via laptop/tablet/phone. It is a bit of a different build than most I have seen here. I am limited to 120V as power source right now, so I am having to rely on two separate 120v 15A breakers. I am doing a 5 gal build so it isn't as big of a problem, but still I didn't want to wait all day on the BK to get to temp. I've put two 1500W elements in the BK that will be fed from the two separate breakers. There is also one of the same elements in my HLT. I obviously can't run all three at once.
This really makes me want to have taken some electrical engineering courses in undergrad! I have had a steep learning curve thus far, so I wanted to see if you guys could review my wiring. You may notice I don't have any switches- it will all be controlled via web browser. I may add main-line switches later on, but I really don't see the purpose for them if it's all controlled via web. There will be an e-stop; it's just not pictured. I'll be putting redundancy in my code for ensuring the three elements won't be firing at once.
I don't have fuses, the temp probes or the pumps shown in the diagram yet.
Would connecting both grounds add any safety? (i.e if for some reason the ground on circuit 1 became disconnected and circuit 1 needed grounding, it would run through circuit 2's.)
Is there anything else I should consider adding? Later I would like to add float sensors to keep from dry firing, or volume sensors (if I can find a good method) for keeping track of kettle volume and a speaker or buzzer.
Hopefully this is legible- I used Visio- If too compressed, I uploaded a copy here
