Rick,

Thank you. I appreciate that. I've been working for several hours today trying to piece together a good diagram for you. It is rather complex to piece together during the design phase but I'm getting there. It will be quite a while until I get to the finish line.

Please be patient.

P-J,
I certainly appreciate the time you take to help out so many fellow brewers! I am not in a huge rush--please take your time. And again--THANKS!

Rick,

Wow... I cannot believe the mind jumps I went through to come up with a diagram that I HOPE is what you are looking for. The contactors with the 240V coils threw me big time. The diagram is based on your planned mission and description. It's also based on my understand of the parts you have already to get the build done.

HD Spa Panel wiring:




Then the diagram: As always - click on the image to see (and save) a full scale diagram printable on Tabloid paper. (11" x 17")



I hope this fits your needs. Please let me know.

I wish you great success in your build.

Welcome.

I think you now understand how very complex that plan was to understand and then draw. It was a woofer (Imagine a wolf howling at the moon) for me.

If not, I could see such a thread to be a huge time saver! Thanks
I am amazed that PJ is doing all this work. I second the notion that a Sticky thread with all the diagrams he's posted be created. I am in the (rough) planning stages of my build and I'm confident the diagram already exists in one form or another.

I might take a shot at web crawling all his posts to see what I can find to put in a thread.

BTW PJ should be getting commission from HBT and others.

Thanks for the drawings P-J. If someone has a technical problem with a drawing, please let's dig into it.

This is great work P-J.

I am in the middle of building my rig and I'm just started considering dropping the gas route and focusing on an electrical route with two elements like you nicely drawn here.

Any one dared to do a rough price calculation of these components.

Secondly I know, by reading other threads, that P-J recommends using a spa panel. Any particular model ?

http://www.homedepot.com/h_d1/N-5yc1...specifications

Is the main reason the cost ? Breaker cost vs. Spa Panel cost ?

Bare with me here, hope is not way off topic.

My main question is how do I get 240V out of the main panel since I have no 240V outlet by the main panel. I see a thick wire going up from the panel but no outlet around the main panel.

I still think I need to put in a break in the main panel and add a 240 outlet and if I do that why would I need the spa panel. I plan to brew in the same room with the main panel, 5 feet away.

Thanks and keep up the good post!

Spa panel houses the GFCI breaker. Usually cheaper than a GFCI breaker for your main service panel.

You need GFCI somewhere on the way to your control panel (even if just inline power cord, like Kal's setup).

Another work of art from P-J. I would happily blow that up to poster size and put it on the wall.

I know it was not in the design specs but my preference would be to use a 3-phase 240V contactor and use the 3rd switch as a latch for the coil with a momentary on switch setting the latch and E-stop cutting power to the coil.
