A single 6000w element on 240V draws 25A
With the 3 phase setup and 3 - 6000w elements wired in Delta - each phase will draw:
6000/240*1.73 = 43.25 amps per phase at 240v.

You are welcome.

When you get into the build stages please let me know if you would like independent controllers for each station. It might help to minimize electrical wiring for your brewery. Each station could (would) be placed for that particular location.

Just trying to help you with a few "mind jumps".

Wishing you the best and GREAT success.!

Have you heard of DIN rails? I would highly recommend doing all of this mounted on din rails. You might pay a few more dollars, but you will save many hours measuring drilling and tapping, and everything is more flexible for the future.

Availability was not the issue. PRICE was/is!
I have received quotes and they were not nice. So you may want to see what they will charge for your system to be GFCI. I am saving the link, it looks like they would be worth investigating.
I know there should be a reasonable solution out there.
