Kevin, if you end up having bad luck with getting it replaced, trying sending a pm to zeus53219. He's packing up my contactors right now, and if he has them asks $22 each plus shipping.

For what it's worth, if I was only going to do one it would definitely be to cut the main contactor. The GFCI shunt is there as secondary to this, and stemming from some of my formal training to over-engineer everything. Thanks P-J, I understand this, at the same time I'd rather keep it...

Agreed. The way I'm looking at it is this: Unless, I'm an idiot and have blown the fuse on my GFCI shunt, and my GFCI has not failed I kill all power to my panel. Unless something has seriously gone wrong with my contactor (or my e-stop switch) I've killed all power past my main relay. If...

Without a contactor in a 240v system your PID would only be able to output between 50%-100% power; one leg would continually be Hot.

Once your question made me stop and think about it, I realized that I was idiotic not to have it trigger the coil, far more reliable a way to kill the power in the panel, even if it by itself doesn't accomplish my goal of killing power to the panel. I'm very happy with the improved redundancy.

That will work just fine. (Provided your PID outputs between 3-32V DC) Actually, I'm going to have to (potentially) rescind that. An SCR could potentially be used find for this purpose, I'm not sure if that exact SCR can be used for this purpose. Is there a part number on it?

Besides the additional cost for a DPST (1-NO, 1-NC) e-stop, I love the idea. Grateful for this thread for inspiring me to go this route. I like saving money where I can, but if there's an emergency I'm trying to stop with this button, I want to do all I can to ensure that at least the...

I've modified my diagram to have my E-Stop kill the coil to my main contactor as well as trip my GFI. I know this isn't necessarily the 'proper' way to trip a GF(C)I, but I believe it to be a safe and effective way of doing so. Am I wrong in this?

I was aware of the leakage, hadn't really contemplated the repercussions on the two element heating lights as they were a very last minute addition which I still might remove. I was thinking about shunting to ground to trip the GFI so that there's no power whatsoever in my panel, instead of...

After months of research and pondering, I've finally finalized plans, and started ordering components. With that said, I've drawn up what I believe to be a fairly standard 50A, 2 PID, 2 5500W Burner, 2 Pump setup. Before I go ahead and finish speccing out and ordering my electrical components...

Are you planning on using a ground terminal block for this? If not, it might be a good idea to ensure a proper ground connection.

@Spartan1979: Almost everything you'd want to install on a back plane: circuit breakers, SSR's, Contactors, Terminal Blocks, Fuse Holders/Blocks, etc. @psbuckland: Thanks! Love that link, definitely seals the decision in favour of DIN rails in my mind.

Correct. No power is transmitted via the DIN rail. If you want to transmit power, you normally use DIN mounted terminal blocks to allow interconnects between your breakers/components.

Thanks for the link. I've been caught up in work, but am looking forward to moving my sourcing to predominantly DIN mount components.

Do you by anychance have a build thread or component list for your build? In my (brief) initial search before looking for advice, I didn't find all that many components that attached to DIN's. I would love to be able to source as much as possible that can be hosted on a DIN.

Thanks. I'll adapt my drawings/components to have DIN rails for the breakers leading to terminal strips, and then the components and ask for feedback at that stage. I thought there might be some more DIN packages for components that I wasn't aware of.

Thanks for the responses. P-J, am I correct in assuming from your response, that I would simply want to design my panel to have DIN rails for the power input and circuit breaking area of my control panel, and then there will be DIN mount terminal strips leading off to my various components...

I've been seriously planning a HERMS setup (240v, 50a, 2 element, 2 pump) for the past three months or so, and have in the last month entered into a partnership with two local brewers/friends to collaborate on a 15 gallon setup. In reading a lot of the threads here, I've come across several...
