Hope this helps
Thanks, that helps a lot!
Why don't you run a single 50 amp 6/4 circuit from your house main panel to the brewery and have a box with equipment built into it to run all your electrical brewing needs? Might as well run some 12/2 WG and have another dedicated 120v 20 amp circuit to run other things. Put the 50 amp GFCI breaker in the house panel. I think a sub panel is a useless cost unless you don't have enough room in your main house panel. Just my 2cents.
From my calculations (which, admittedly could be wrong), doing the sub panel will be considerably cheaper than a full on control panel with everything contained within, plus it gives me some flexibility to change things and add as I go later on. I like the modularity of it in particular since I plan on getting an 8 space sub panel, but only plan on using 4-6 to begin with. Oh, and I will have the 50 amp GFCI in the main panel which will then run this sub panel.
I actually already have a dedicated 20 amp 120v line right there as well, and I've been thinking about using that for the vent hood, march pump, and submersible pump, just daisy chaining some switches to boxes, that way I could keep the 50 amp line for just 240. If I run both elements at full power, I'll be over the 80% mark, so I think it would be best to have the smaller 120v parts on the separate circuit.
I looked at the prices of contactors, a big box, plugs (those twist lock power plugs add up quick!), all the small items, etc. Plus, thinking about doing all of that routing for the wiring would make me nervous. If I were to hardwire everything, I think it could bring the costs down dramatically, but it would be difficult for me to add to it later on, unless I oversized the box and left enough room inside for all the components. I haven't ruled it out completely, but when I was initially looking at doing one big box, the costs were adding up a lot faster than I expected, and that is when I was thinking about the sub panel. Before the sub panel, I was actually thinking of just bring down the 6/3, and then splitting it off inside multi gang boxes to feed the switches as needed but the sub panel in total will really only be about $80 in total for the panel and the breakers, which I don't think is that bad.
blktre, do you mind if I ask what you put in your control panel and how much it cost?
