Default 2 Vessel, 2 PID, 3 element 120V Control Panel wiring

Ok, so my last post didn't go over so well, and I think it was due to a lousy title, and a PDF of my circuits. So, here it is with a more descriptive title, and a png

So heres the lay of the land for me:
I run a almost 3 vessel system. I only have 2 tuns, 1 mash tun, and a BK. The 3rd vessel is just for wort collection prior to boil.

I have 2 2000 watt elements in my BK, and I'm looking to install a RIMS system for my mash tun.

I started looking at PJ's diagrams, and basically I want to hybridize http://www.pjmuth.org/beerstuff/imag...asic5-RIMS.jpg and http://www.pjmuth.org/beerstuff/imag...4-simple-1.jpg, with a 3-way switch where the power switch is on the RIMS diagram and controlling plug 2 on the a4-simple diagram.

You guys following so far? The only other hiccup is that while I'm using 120v now, I would like to move to 240 in about a year when I move out of my current place, so I'd like to use as many 240v parts as possible.

I have visio, but I couldn't find a good set of stencils to draw something even remotely close to P-J's style, so I did the best I could with what I had. If it doesn't make any sense at all then I apologize. From this, I think I have a good idea of what parts I need to start sourcing, but I wanted a sanity check that a) this plan would work, and b) that i'm not over complicated things and wasting money on stuff.

Thanks for any input! Feel free to tear me a new one

2	Parts Express	110-418		Marinco L5-20 Locking Plug (Male)		13.61	27.22
2	Parts Express	110-416		Marinco L5-20 Locking Plug (Female)		21.26	42.52
					
					
					
				Grand Total:	849.21
The biggest thing I'm confused with/find overwhelming is the terminal blocks. I was thinking I'd run a bus for everything that had multiple connectors, but I'm reevaluating currently because that will add a lot more cabling between the front face and the internals. I'm going to try and draw up a better diagram now...

To trim some of the $$$ Auber has a nice heat sink, or you can find them for about $5-$15 on ebay...

I am currently sourcing all my bits and bobs right now too.

I will just be running 1 PID, and going with the ebrew BiaB kit, but will ask them to sub push button switches for the 2 way switches.

Best of luck

Tim

Ok, heres my best imitation of a P-J style diagram. I don't think I could have ever gotten anything even remotely resembling this if it hadn't been for all the stuff I found on here.

Specifically thanks P-J for your awesome diagrams, they were my inspiration

Hopefully this is pretty readable, its pretty chaotic but this seems like no easy build. The only thing I didn't show was Alarm wiring, because I'm not sure how I'll pull that off? I was thinking of doing RIMS-OFF-BK for an alarm toggle switch, and then wiring in each respective PID into their half, if thats not possible I'll just wire in 2 alarms each with on/off switches.

Thanks again for any input! I'll definitely check out ebay for a cheaper heat sink, thats one of my biggest ticket items right now!
