Could any of the experts here help me with the drawing below?
I intend to run a twin element Kettle as shown. Each element has it's own 20 amp breaker.
I will also be adding a PID/SSR to control a HLT.
Due to amp loading limitations, I need a selector switch to select between powering the HLT element or the second kettle element. One element on the kettle could always operate so it would be constant.
That way I can start heating the first runnings while doing the first & second batch sparge.
I know that my setup is not ideal but there isn't a practical option for dropping a dedicated 240v 60a circuit in my detached garage. Plus, this is more portable if I ever moved.
Your drawing shows each element with its own power supply, but then you say you need a switch because you can't share power - which is it? Why run 2 power supplies if you can't run both at the same time?
Also, if you have 2 kettles, but only 1 PID, you're going to potentially run into trouble, unless you switch temperature probes between them and only run one in auto mode and run the other in manual only. But even then, if you plan to have both elements on at the same time you'll need two PIDs. One PID can't reliably be used to heat 2 kettles, especially not 2 kettles at the same time.
