I have a 40A SSR on its way to me, and a PID. My local Home Depot has 4500w/240v, 3000w/240v, and 1500w/120v elements. I boil up to 13 gallons for 10 gallon batches. I think 4500w is too small for what I want. I thought of running two elements (4500 and 1500) on two different circuits (4500w on the PID, and the 1500w on a seperate 120v circuit.
But can I run two 3000w elements from the same SSR? What about 4500 and 3000? That would work out to be about 27A for the 6000w, and 32A for 7500w. I know they would both be controlled by the PID with no differentiation between the elements.
I'd just wire the elements to the same terminals of the SSR. Correct?
