Thanks for the replies. This is the latest version of my wiring diagram including the cooling fan and DC switch. I didn't want to have heat sinks protruding from the panel box so figured having a to move some air inside would be the next best option. Any additional input is, of course...

Anyone running cooling fans in their brew panels? I see a lot of people putting heat sinks on the SSR's but not a whole lot of builds with fans to push air over the heat sinks. I was thinking of putting a computer fan in my build to draw air across the SSRs. You can get pwm fans so I...

Welp I suppose there's nothing left to do but build. You've been immensely helpful. Thanks again.

Good points. Guess it would make more sense to just have both element and pump have an auto and manual setting I'll have to see what else is on the circuit. Make sure it doesn't kick at a bad time. Think having the indicator lights on the 5 volt side might make sense like you said earlier...

Doing three way switch so can have the pump on manual or bcs mode. I have the hot line for the element ssr wired into the pump switch so that the element can only get power when the pump is in manual mode. I wonder about routing that much power through the pump switch though. Can those...

Is this how you'd wire up the switch diagrammed to the right in real life? I'm almost ready to start smuggling the components past my wife and into the safety of the basement.....

I'll have to buy a copy. Thanks for the heads up!

So the way things are set up now I would need 120V capable indicator lights, and switches, correct? Would these be suitable? 3 way switch : http://www.ebrewsupply.com/shop/indicators-switches/3-way-1-no-contact-switch.html NO contact block ...

Sorry for small image, here's a better one. Why must the image insertion be so asinine for forums?:cross:

Alright, here's my first shot at a wiring diagram. I meant it to have the following features: 1. Pump with manual (always on, for RIMS and wort transfer, BCS control for wort chilling). 2. Element cannot turn on unless pump in manual (always on) mode. 3. Powered indicator lights for...

I've notice people putting what look like breakers in their panels. Are these to protect the individual components that the panel is powering? E.g element running at 17.5A, pump running at 4A? Otherwise I would imagine the main electrical panel (circuit box) breakers would kick before any of the...

I haven't found one panel that is alike in all my searching. It's really interesting how unique they all seem to be. So the PWM function controls the current level to the element, it's not just on or off? I think if I run both the pump and element through the panel simultaneously it's going...

Haha! It's hard to find one where it's really clear where all the wires are going and what they're attaching too. Your panel is google images famous!

So there is no fuse before the element switch because you want it to run up to the full 20A? And how about for the pump, would you pick a fuse that was a little above the maximum current it would be expected to draw?

So when the Estop is closed it routes the hot directly to ground? What are the resistors and fuses for?
