Seeing this in another post (30a inline GFI)
I had an idea to add a 220v element to my current setup
Basically take that cable and add a small project box with two SSR's and an appropriately rated DPST switch, out to a twist-lock disconnect and a 5000W potted element. Then make a removable cable probably with some kind of water resistant connector to go between the small project box and my current control panel for the SSR control wire.
Then I can continue to use my 120v system on two separate 120v circuits, found in any kitchen wired to code, or I can get a 220v outlet dropped in my garage, and I can use my current PID to control the 220v element, and my pumps. Which would be nice to heat water up quicker, or do a 10gal batch.
How does that sound, does what I said make sense?
