You could configure the 5500W elements so that they can run on 110 or 240v. So if you just need one to maintain heat while the other one needs to be full tilt then that may work. a 5500W element on 110 will only use 1375W, dropping your load consumption.
Doing the math, 2 5500W elements is going to put you at 46Amps which is a little close for comfort for a 50 Amp load. put a 60 Amp breaker in there and add the 1500W 120v element puts you at 58 amps, way too close if you ask me, you'll be dealing with nuisance trips eventually.
I think you really need to do another power survey and see where you can cut back some.
If you don't mind, please take a look at the attached file. This is a work in process so I still have more work do do on it, but thought you might see something in the early stages that will keep me on the right track.
I've had a heck of a time finding a tool that I can use and then manage to post it on HBT. Attached is a zip file containing a pdf of a visio... wow, I need to figure out a better way.
Some notes about what I have so far...
1) This is just the power side.. I'm still debating control (PIDs, Brewtroller, or BCS460).
2) The selector switches should be 3 position, I just couldn't find a symbol.
3.) I'm thinking I should replace the switches with relays, but I don't know parts, sources, etc.
4.) I bought a 50amp GFCI to put in the panel and plan to have a receptacle fairly close. The rig will need to be portable, so I'm thinking I need 10-20' of cord on the rig.
This is open for suggestions, input, comments. I'm also hoping to get some input on sourcing.
