Finally got all of my components together, and I'm getting ready for the build. Any good resources out there on how to build these things? I was looking into having an electrician do it, but i'm having trouble finding one.

You're right on track. This is the process I'll be using, albeit a bit smaller. A couple things...the 5500w elements will pull 30A each. If you want to run 2, you're gonna need 60A total. Rather than a single high amp line, it's easier to control 2 smaller ones. Be sure you're wiring is 10AWG and that your breakers can handle 30A. You will only need both elements for getting to temp, then the single one can handle the boil. You will want insulation on everything.

Chilling may be an issue too. Did I miss what kind of chiller you're using? An IC becomes impractical at this size. CFC is probably best....plates can clog and you don't want to fiddle with a clogged filter sitting under 30 gallons of boiling wort!

Lastly, get rid of the HDPE grant and go to stainless. You don't want plasticky off flavors ruining 30+ gallons of beer. Besides that, it gets soft and who knows what will happen with that much hot wort pressing against the sides. You can get away with a smaller grant since it's not the full volume....a sanke (or two) might work in a pinch.

Little late but this is a Diagram P-J drew up for my system that's the same size as the OP.

Yeah, got 2 50A lines put in.

Good to know, thanks.

So, due to trying to do this on a budget, we decided to eliminate HERMS at least until we decide we need it. So there's no coil in the BK, and no device to maintain mash temp. We're going to rely on insulation and thermal mass to maintain temp. For chilling, CFC. Based on my research, nothing else is going to be as effective for the price.

Since the initial drawings were done, we've acquired an additional 3 stainless 55g drums. So now everything is stainless. And I'm thinking of thermal wrapping and wood cladding everything, to make the best use of energy/maintain temps better.

Thanks, but I do have a diagram from P-J (I think on pg. 2) . Mine is more minimal than yours, as our "HLT" does not have any elements in it. We're just going to pump hot water from the BK to the HLT for sparge. Once we know what the temp drop is over time, we should be able to ensure the water in the HLT is always hot enough.

I've built loads of stuff from schematics before (varying degrees of success of course), but never with high power stuff, which is why I'm nervous. I also want to avoid making dumb noob component layout mistakes, because I'm new to this kind of building.

If you have 50a breakers, 10 ga wire is not sufficient. I believe you need to run 6 ga wire. The prior comment was that if you used two 30a breakers (rather than one 60a), each of those could use 10 ga wire.

ok, thanks. i need to verify exactly what the service is before building then i guess. it's in a rented space and the landlord set it up. hopefully it will be usable as is.
