I am wanting to build an EBIAB system with 240V element to PID controller. I currently have a 8 gauge 3 wire going to electric oven in basement that Im taking out. I want to run the 3 wires into a spa GFCI panel and then into brew controller. I have looked through many posts on this subject and keep comong back to several replys with a wiring diagram from P_J and looks like he is no longer on site. The images are not available and was wondering if someone out there had them. I am not sure how to proceed with wiring my system. Any help would be appreciated
Looking for schematic from older post

You want anything other than element control (pumps, power meters, timer, whatever)? Here's a really simple control design that will work with three wire 240V (no 120V usage in panel):
Just ignore the unused neutral wire, since you don't have one in your 3-wire feed.
Brew on

Thank you for the diag. I have a question. Can I run a single copper wire from main panel to spa panel to add ground. Then using 8 gauge wire that all ready exists would run black wire to spa breaker, red wire to spa breaker, white wire to neutral buss bar, copper wire to ground buss bar and white pig tail from spa breaker to neutral bus bar. Then I would have 4 wires from spa panel to run out to brew control panel to get by 120V outlets to run chug pump in addition to 240V for 3750 watt boil coil. I get confused when looking at main panel and only have 1 buss bar with copper wires, white wires and my earth ground,, which would be bonded and basically running another copper wire to spa panel which would be considered subpanel to its own ground buss bar, is this thinking correct.
