Well then I would say wait until you move and then build a rig to run off of a properly wired 220v line. And SPARKY you were thinking the same as me and my brain just decided to F^ck up on me. Good call on wanting to check the overall existing loads.

I am working on the assumption that the current 120 line will be upgraded to a 220 line in the future. This is just how I plan my projects. What will be the possible future upgrades? Is there anything that I can do now to make what I have upgradeable. If the difference in price is very small, which it is with a 120 and 220 element, I go that route. This is just my method of reasoning.

And... I was just trying to answer the question. Thanks for confirming the 75%. I love being right. It seems to be less and less often anymore.

I'll definitely be doing 220v when we move, in fact the wife is all for building a designated brewery room/lean to/something so she won't have to wrestle with all my gear floating around the house. I'm thinking I will probably just suck it up, grab a 120v element with the same threading size so that all I will have to do is swap out the element down the road. I'll pick up the necessary wire and plugs for a 220v setup, and just wire it in as 120v for now. I just hope the 1000w or 1500w element can get the 10 gallon batch to boil in a decent amount of time.

Am I good on my math in saying that a 25a SSR (currently have) would run a 1500w element running at 12.5a?

Seriously, it'll take you probably two months just to order all the parts/pieces, build a control panel, drill the holes in your kettles, wire everything up, etc.. If you're moving in two months, make a detailed plan and start ordering parts for a 220V system. By the time you're done putting it together you'll be moved into your new place.

Check the voltage rating to see if it will last through the voltage upgrade (should be rated for 400V or more for a 240V service)

the 25A rating will run a 25A resistive load, assuming you have it properly heat sinked and all junctions are properly wetted. You can always run a lower current load with the device. Although there is a sort of theoretical minimum load, below which the resistance is so low that the device will not properly turn off. In this case you just need to add a resistive shunt circuit to clamp the output.

Just FYI - I use a 40A 600V SSR to run my 5500W element from a two pole single phase 220VAC source. I am using a Crydom at the moment although i also have an Ebay china SSR that has been tested. I overspec'd because the thermal dissipation challenges increase with switching rates and I didn't want to worry about junction temperatures.

Oh and you would cook 14ga wire if you tried to jerryrig a 2-pole service for this project.

Yep Jkarp I must be wrong... Guess I don't know what I am talking about.

Turns out, I mixed up my SSRs, the 25a one is running my keezer. Guess I'll have to order one or 2 40a ssrs anyway. I'll probably get the ones from Auber since I also need to order an RTD or other temperature probe to attach the PID to my kettle.
With any luck, I could pull the few pieces I need together pretty quick, all ready have a control panel, but I will probably drag my feet for a while to see what happens in the near future before putting time and money into this.
Thanks for the help.
