Don't know where you work, but make sure you have plenty fire extinguishers, because that's the dumbest thing I have heard today. Please explain why you do this to OSHA or the insurance company when something bad happens. Your changing the UL listing for the wire if you melt off the insulation...

I am now the Brewer at Helltown Brewing

If the lugs are too big to properly secure and make good contact with the wire then you need to get smaller lugs or a larger gauge of wire. But also watch out so it will fit in your twist loc sockets. Originally I don't think it was terminated, just wired to the lug. Might be wrong. As others...

Seriously????? You had a fire in that panel and you don't think replacing the contactor is a good idea? The amount of heat generated at that failure point will weaken the metal and change its property's. You will have another fire, count on it if you don't replace the contactor and the affected...

Wow this happened again! Did you use one of those cheap multi tool crimpers, if so, get a real crimper and re crimp all connectors.

TRUB will be doing one soon though Helltown Brewing. I just have to get the prices together. Looking early in January. I'm just too busy brewing right now. Thanks

You could use a set of stainless rods, space them and when contact is made, turn on a input to your controller. I thought of a mister like in the grocery store for produce, a fine spray of water will knock down the foam.

Well as an electrical engineer, who has designed many many control panels in the nuclear, semiconductor and steel industry, you are wrong about what an EMO does. It's an emergency off, I never said to use it as a disconnect. I said in case something goes wrong it is nice to have a local way to...

I absolutely hate that resistor idea. If it were a good idea you would see it used in industry. It works as a test button only. By doing that you are outside the rated operation of the GFCI and limiting the lifespan as well.

To answer the 240 or 120-120 per leg, the device when the SSR is off will still have 120 unswitched and 120 floating on the SSR controlled leg. Since you need a circuit (2 or more wires) the SSR is opening the circuit and stopping the flow of current. You could do both legs but its unnecessary...

Looks OK, you really only need to control one 120v leg of the 240v heater circuit. Might save some money. Just make sure you make your connections secure and not with a cheap crimp tool.

May have lost magnet. Call Chugger, they are outstanding when it comes to tech support.

Id grab it if it was closer! Looks like it has a glycol system

It can be done. First determine how much expandability you need. Don't want to limit yourself and find out later your stuck. Automation Direct has some great PLC that will not break the bank. EBay is a good source of used gear. Get the software first for the PLC you want to use, build your logic...

NSF is national science foundation, it's a cert, not a manufacturer. I have the same kegs, I think they are made in India.

Nice! You may want to get some split loom tubbing or wire wrap to protect the wires from the door to the wire tray, last thing you want is a wire smashed in the hinge or caught on a relay that pops out when you open the door.

You only need to control one leg of a 240v 2 wire supply, BUT, if you want to kill power completely for servicing or such, you need a contactor or disconnect. An SCR will still pass voltage even if it's control signal is off.

It's not a PID, it's called a temperature controller. A PID is a function of the temperature controller. It's like calling a gun a firing pin. Please stop
