Is there a reason you used a 15A CB to power the pumps, relays and electronics? I noticed the 5A protection for the PID's, but wouldn't 10A instead of 15 be better? I think normal Chugger/March pumps draw less than 2A, guessing the total draw on that leg under 5, definitely under 10. Or is that just the same pic P-J uses in all his schematics?

If you can find a 10A single pole DIN breaker, then go for it. My source only had 15A. Looks like they now offer a 6A option, too. I bought my breakers from ebrewsupply.com - but really, the breaker is only protecting the wiring, so by going with a 15A breaker it allowed me to go down in wire size. I suppose a 10A would have worked, but there's no harm in going with a 15A.

Default Just read this entire thread.

I would really like to make my own schematic, but MS Paint makes me drink too much. What software does P-J use to draw his sweet plans? Anyone know? How about you Kevin? I have resorted to pen and paper, but I would prefer to make a digital version. Thanks guys.

That's a great question. I have no idea what P-J uses. I know he's compiled quite the cache of PIDs and terminals and other graphics to use, but whether he uses a specific program for doing diagrams (I checked a few out and they all confused me more than needed) or maybe he puts in the time on MS Paint or something else.

Me - I used P-J's diagram and modified it in MS Paint, and then he used his P-J magic to make it look better.

Pen and paper is better than nothing for a start, that's for sure!

Thanks for the quick response, and also for demonstrating that I can run my neutral through my contactor. I am going to try making a diagram in GIMP. Also, thanks for running your neutral through your contactor. I bought a 3 pole contactor because it was cheaper and just dont't like the look of that unused pole. I just wasn't sure running the neutral through it was legit.

I don't do it any more, because my 3 pole contactor was a POS and got sent back. There's no reason I can think of why running Neutral through the contactor would be an issue. Definitely don't run ground through it, you don't want to break your path to ground in case something goes south in the panel.

Is there really any advantage to it, assuming that the contactor is normally open for both hot leads where they enter the panel? Perhaps I'm missing something.

The only advantage for me is aesthetics... I needed a 60 amp contactor and they were mostly all designed for 3 phase. I knew it would suffice and that I could use only 2 poles, but I like the look of three 4AWG wires leading into it.

No advantage I can think of, other than the "hey, I have 3 terminals... why not use them all" mindset.

Default Outstanding thread! Any updates?

I am just about to start a build that looks like it will be based upon this thread.
Your process and troubleshooting have been very informative.
I appreciate the iterations that this thread has gone through. Did you ever post a link to the revised 2352 version with the safe start interlock included?
Also if there were any changes you would make what would they be?

Thanks and enjoy your beer!
